Fix : pressing space during a stability certificate won't restart the timer.

Fixed : Unsupported instruction sets would appear in the dropdown

Tentative fix : AVX512 would display weird behavior in advanced thread mode

Fixed : Schedules created with v11 would not load properly

Fixed : Autoupdate was still kicking in when it is not yet supported

Fixed a regression introduced in 12.0.3 : OCCT would fail to start on computer where it was never started before

Fixed : the monitoring driver may have been in use before starting OCCT

Fixed : The upload to ocbase setting was ignored 

Fixed : The font size setting wasn't kept after a restart

Fixed : After restarting a test that detected errors quickly, OCCT would detect a negative number of errors

Fixed : The instruction set wouldn't appear in the Power test summary

Removed the CPU and 3D test start log lines in the power test to avoid confusion

"Run all" CPU benchmark is now the default (without a config file)

System - Bronze stability certificate is now selected by default

Fixed : The autoupdate will properly restart OCCT and stop displaying a cmd box upon updating. As the issue is in the client, OCCT 12.0.0 and 12.0.1 will still exhibit this bug when auto updating to 12.0.2 or later versions. Starting from 12.0.2, this behavior will be gone.

The top-level bar will now remember the CPU&GPU selected

The top-level bar will try to auto-select a relevant GPU instead of the first one, which was often the iGPU

Added motherboard infos to system information

Fixed an exception that could occur if the number of physical cores and logical cores was badly detected ( mostly on older CPUs)

Added an option to save a debug file with system information and monitoring information - will come in handy to improve the top level bar auto-sensor picking

Fixed : the duration was off in the text of the UI ( the stability certificate durations were right, this is just a display issue )

Not forgetting about you translators, bugfixes are occuring in a side branch, please bear with me !

Fixed : The Drive flag for monitoring wasn't working

Fixed : The about window was not displaying license status and HwInfo version

Fixed : A memory leak would occur when OCCT was minimized and the graphs were displayed

Fixed : a dependency was missing, causing a crash of the test when started on bare Windows installations

Fixed : The GPU select option (and test all GPUs) was missing from the Power test

Rewrote 70% of the application - switched to net core. UI will feel much more reactive, will use less CPU, at the cost of some memory usage

Removed a lot of dependencies - OCCT has never been THAT portable

Added the ability to launch an external program to OCCT through the Monitoring Only test

Introducing a brand new UI with lots of features. The most proeminent is the top-level monitoring bar that is slated to improve a lot over time !

You can now more easily filter monitoring values. Use the right click to do so !

Graphs can be clicked to pinpoint values accurately. Give it a shot

Introducing GPU, System, and System (no 3D) stablity certificates

Added report comparison feature - contact us for more detail

The translation system will be released in an upcoming version of OCCT - this is english only for the time being. Sorry for that delay - it definitely needs some more time

Fixed a regression introduced in 11.0.22 related to stability certificate upload

Fixed a regression introduced in 11.0.22 leading to a crash when saving reports

Updated monitoring engine to deal with the recent security update released for Windows 11

Fixed : the window was still somewhat resizeable when monitoring was disabled for a short time

FIX : The serial numbers for some components were missing in the JSON report

Fixed : The upload would still occur if it was disabled in the settings

Added a fallback to another endpoint to the upload in case it fails

Fixed : The GUI would refuse to start if no GPU was detected

Instruction Set : Auto will be set to AVX2 instead of 512 as this option has proven to be much better at error detection ( for now )

The initialization time won't be counted in the global timer anymore. This means the test will apply the loqad change roughly 2s after starting, time for it to initialize

Fixed : Much smoother curve on older GPUs

Fixed : the load was set too low on RTX4090, resulting is a steep jump between 99% and 100%

The test will have a much better scaling on newer GPUs ( RTX4090 especially )

Fixed : uploading would fail in edge cases ( those issues are tough to reproduce )

Fixed : a rare bug would prevent stability certificate from uploading properly

Fixed : OCCT Command-line would error out when loading its config file and revert to the default values

Fixed : The memory available for testing was reported as 1GB instead of its real value

Fixed the upload issue - the previous fixes from 11.0.14 are now back in the main branch

Revamped the way OCCT is listing GPUs for better compatibility with ARC GPUs

Fixed : threads were competiting too much for a single resources, resulting in a loss of efficiency in high thread, small data set scenarios ( thanks Anders from Asetek ! )

Fixed : If a duration was exactly 00:00:00, the report would display it as "invalid duration" in the log

Release 11.0.14 has a critical issue with uploading that will take time to diagnose. 11.0.13 has been relabeled as 11.0.15 to give me some time to diagnose the issue. Sorry !

Big update & support for newer CPUs and GPUs ( Arc770,RTX4k...)

Fix : the test would refuse to start on a second GPU if it wasn't launch on the first GPU at least once ( Thanks PCSpecialist & Devin Hartley ! )

OCCT now creates a file named "LastMonitoringValues.json" in its temp folder which will always contains the latest sensor information ( Values, minimum, maximum...)

Fixed : The enterprise report would not properly display the total amount of memory available

Fixed : Saving the report now doesn't hang the GUI, and the cursor will be in a waiting state, as this process can last quite a while. A better fix will be coming later on, with, ideally, a progress bar.

Fixed : a regression caused the csv file only to contain enabled sensors. It will now contain all sensors regardless if they're enabled or not, as intended.

Fixed : when chaining several periods of 3D adaptive running on several GPUs, the test would be wrongly flagged as crashed

Tentative fix : wrong GPU order was used when several GPUs are present and tested at once

When no GPU is selected and the system has several, only the first one will be used (instead of all of them)

Fixed : on CPUs with E and P-cores, all the threads of the Memory test were assigned to E-cores for an unknown reason. Their affinity is now fixed to get around that issue.

Fixed : in case there was a LOT of lines in the report, OCCT would fail to generate the report. The report is now limited to 13000 pixels (which is already quite something)

Fixed : the status was wrongly set in the JSON file following 11.0.8 fixes

Fixed : the date and times were not properly displayed in logs if they were above 24 hours.

"test" is now the default verb if you don't specify one

Fixed : when the report was saved on a slow drive, there was a chance that the saving was interrupted before being fully completed

Fixed : settings were not saved properly on exit unless you started a test in the Personal/Coolermaster edition

Fixed a graphical alignment issue in the 3D adaptive configuration ( minor fix )

Added word wrap to fix some lines being cut using russian language

Fixed : the test configuration besides the currently active test should now all be saved when restarting OCCT

Fixed : The test config wasn't properly saved

Fixed : Gpu Standard settings were not properly loaded and saved in schedules

Fixed : Ukrainian and Russian translations text wrapping ( Thanks Serhii ! )

Fixed : in Windows Audit mode, Physical GPUs were considered Virtual, due to DirectX not populating properly its registry values. This is now handled correctly. Thanks Victor !

Fixed : the command line edition would skip the prerequisite copy step if the GUI edition was never run on that computer

Fixed : the retry button will only be displayed when a stability certificate or benchmark fails to upload (Thanks Emie !)

Fixed : the log wasn't fully cleared after a benchmark/stability certificate upload

Fixed : 3D adaptive will be displayed correctly and its config will properly show in the Enterprise edition report

Fixed : Stability certificate would fail to start if the following conditions were met (bear with me) : you were using a v10 config file without restarting OCCT, and you start a stability certificate without changing the type/level of the stability certificate. 

Fixed : OCCT Command-line was unsigned which caused the program to refuse its license file

If an error or WHEA error occurs right at the end of the test, it may be reported when OCCT is switching state, which will result in the test not stopping. I added additional guards against these cases

Fixed a typo in the platinum CPU stability certificate description

Rewrote and optimized OCCT's core scheduler

Every test (but linpack) now detect if the GUI has crashed and stops accordingly

Switched to 7z for the internal format of my tests to save exe space

The test files are now upacked on startup to gain time when starting

Dependencies are installed upon startup (this is especially true for the new 3D test)

Added the ability to stop on WHEA error ( enabled by default for Benchmark and Stability certificates)

Sliders can now be controlled using up and down on your keyboard for precise selection

Introducing the revolutionary 3D test, based on Unreal engine, with dynamic load options !

Introducing Variable mode, where the load will gradually increase from a set value to another, at a rate you specify. Test your whole GPU Curve with a single click !

Introducing Switch mode, where the load will switch very fast between two set values. Perfect for generating transient loads !

Added a retry button in case the upload fails

Introducing Stability certificates, allowing you to test your components using a predefined test, and share your report online to prove your computer is stable. GPU and System stability certificates will come later !

Available for CPU & Memory at first, in Bronze / Silver / Gold / Platinum levels

The number of slots per license is limited ( each report consumes a slot). The number of slots depends on your license, and Patreon sub level. I had to do this as a single certificate can be heavy, and storing that data is costly sadly.

You can manage the slots in your account menu

Added verbs to the command-line options of OCCT GUI & Command line ( use --help for more info )

Greatly updated the report - it is now much closer to the stability certificate display of my website

Fixed : without a license, if this part of OCCT was left open, the popups would pile up and you had to wait and click X popups. Now, only one of them will be displayed.

Only the first core will be checked by default instead of every core. This part of the UI screams for clarification.

Fixed : Auto and Advanced thread modes would not behave properly on CPUs with more than 64 cores

Bugfix : The CPU test, if launched fast & repeatedly in Fixed thread mode, may crash immediately after starting

Bugfix : Graphs with high variance were overly optimized and too much data was visually lost in the graphs (Thanks Emie !)

Bugfix : the auto-updater would fail in some circumstances

Bugfix : in the "license will soon expire" warning, the number of days left wasn't properly displayed

Minor improvements to the benchmark upload algorithm, including a higher timeout

Bugfix : it is now again impossible to change the currently active tab when a test is running

Bugfix : The waiting screen can be displayed several times in the monitoring section

Alder lake CPU's e-cores were incorrectly considered as having HT enabled in advanced thread mode

Bugfix : On some rare occasions, no cores were selected in the Advanced thread section when first displayed

Fixed : the per-core usage wasn't appearing for Intel CPUs with P-cores and E-cores

Fixed : when an error was occuring on a thread higher than the number of logical cores, no message was present in the log

Fixed : when the test crashed, no message was present in the log

Fixed : the benchmark upload would fail in Pro versions

OCCT will now kill any lingering test process upon starting a new test

If autostart is enabled, the last known status won't be displayed

Chaining Power Supply and 3D tests will now work properly (Thanks Jimms !)

Fixed : the SMBus flag wasn't working properly (Thanks Mickey !)

OCCT's window will now correctly respond to WIN+arrow shortcuts (Thanks Thierry !)

The graph lines won't disappear when changing OCCT's skin ( Thanks xixou2!)

The Graph update interval will be properly saved in OCCT's settings

AVX-512 was incorrectly reported as missing on CPU that fully support it (Thanks Michael !)

Virtual GPUs created using RDP/MSTSC won't appear in the GPU selection window and interfere with the test ( Thanks Austin ! )

The summary won't display 0MB when the test is starting, it was confusing

Fixed : Graphic card selection button looks was off

Fixed : if you used a card with no OpenCL support, the warning would be displayed every second in the log, instead of one

Fixed - the big status indicator wouldn't change its shape and color if stop on error was disabled

Fixed : the scores would not appear in the cards ( they would appear in the test log only) (Thanks Jack !)

Fixed : the autoupdate won't work when OCCT was launch from a pin in the taskbar or from the Windows search function

Fixed : the core usage tab would use some "Utility" sensors instead of Usage sensors if using Hyperthreading

Fixed : restored the proper look for a few buttons ( reset min/max, reset column sorting)

Fixed : the monitoring layout was not properly restored upon startup ( Thanks Ash ! )

Fixed : 3 graphs would result in 3 one-row graphs instead of one row of 2 graphs and one row of 1 graph ( Thanks Ash ! )

Fixed : multiple GPU will now appear properly in the system information ( Thanks MaCK0y)

Fixed : restored the proper look for the "delete period" button

If your computer crash during a test, during its next startup, OCCT will now display its last known state before the crash in a popup for you to review (Monitoring, log, everything is in there)

The last status will now maintain 5 different files to avoid corrupted states when the crash occurs exactly when OCCT is writing to the last status file

Implemented much more accurate timers for the test execution

Removed tooltips from the test configuration area

Modified the delay for the tooltips to appear

Fixed - the tooltip sometimes appeared when taking a screenshot of the app using the screenshot button

Fixed top-level button tooltips. Thanks Сергей !

Fixed an exception that could occur when opening certain popups ( OCCT - Advanced thread settings mostly)

Updated the monitoring engine - better ADL support

Revamped the graph tiling algorithm, and removed the limit to the number of graphs

Monitoring graphs will now properly display negative values

Updated the settings model to 10.0 - older settings will be reset upon startup ( sorry )

Added Linpack version 2021 - fully updated, works for AMD CPUs as well

Rewrote the upload code to pave the way for the future

10.0 will be the minimum version required for uploading results

Greatly improved CSV generation speed and accuracy

Rewrote the Enterprise edition report : it's brand new and much modern, featuring dynamic graphs !

Added a visual indicator to which sensor is selected in the report's graphs. Thanks Сергей !

Removed lots of unused dependencies since the switch to the new Enterprise report

The new report fully supports negative values

The HTML report is much faster to generate

OCCT will properly recognize system information on computers using Turkish language

Fixed a crash that could occur when copying the test log to the clipboard

Fixed the Core graph color for the OCCT Skin

Fixed a rare NullReferenceException within OCCT Command-line

The auto-update was broken in v9.1.0 and v9.1.1 - sorry, please update manually to this version

Fixed a concurrency issue if several popups would be displayed at the same time

Fixed the close button color for the version update dialog

Improved GPU detection algorithm ( more to come on that topic later)

A few graphical glitches when using the cooler master skin

Fixed a crash randomly occuring on newer AMD drivers

Huge optimization of the GUI (CPU & Memory usage)

Added a reminder when your license will expire. It'll appear once when you have less than 14, 7 and 3 days left on your license

Found a workaround to a WPF bug that made the monitoring table look sluggish if a tooltip was displayed anywhere in the app. The whole app is feeling much more responsive, and CPU usage went down

Removed annoying dotted lines that would sometime appear in screenshots

Using the Coolermaster skin unlocks the test report

Increased the benchmark upload delay to better deal with slower connections

Fixed : If a previously saved test (Enterprise) or a test saved in a config file generated from a computer with several GPUs ( Personal, Pro) was executed on a computer with fewer GPUs, it would result in a OCCT hang. Thanks Zack !

Fixed an issue preventing OCCT from saving the last schedule displayed in the settings

Fixed the auto-close and auto-save-report switches from properly working ( Thanks John !)

Fixed a critical issue in OcctCmd refusing to start a Cpu test if certain settings were set. The fix may require you to regenerate the test files.

Updated Espanol, Italiano, Portuguese and English languages

Removed an empty tooltip on the close button for the flags window in the CPU sysinfo

The max alert value in the report will now only appear if it has been reached

Fixed an issue with OCCT CMD not properly showing this value

Fixed a CPU Benchmark crash if your Windows's username contained international characters ( Chinese, etc ) ( Thanks a lot seunggi ! )

Added Benchmarks for CPU and Memory to OCCT !

Added a graph bar to the benchmarks for comparison purposes

Added meaningful tooltips to the graph's bars so you can know quickly what's going on

OCCT now uploads all monitoring data along with the system information to ocbase

Prevented tab change in all cases when a test is running

Improved parsing of Motherboard properties

The "Fixed" thread mode doesn't force thread affinity anymore - this allows this mode to follow CPPC preferred core mechanism. The drawback is you don't know, in this mode, which core produced an error

 Added "--cpu-benchmarks" and "--memory-benchmarks" command line switches to add benchmarks to the current schedule

Fixed a random false positive that could ( not always) appear during a steady load test lasting for more than 6 hours. It resulted in one error detected per thread in the log window

Fixed another rare bug that could crash the GUI under special sensor conditions (Thanks Vasko ! )

Fixed a rare exception that could occur in updating the graphs if one of your sensors was slow to update ( Thanks Santiago !)

Fixed an exception that could sometimes occur when doing very long tests ( 12+ hours). Thanks AMD for finding this !
