GPU:3D and Crossfire configurations

If has been confirmed that there's an issue with AMD drivers in crossfire mode when using GPU:3D in the following configuration :

  • Error Checking mode ON
  • FullScreen mode ON
  • Shader Complexity 8 only (others work fine)
  • AMD Crossfire configuration only
You'll get false error reported.

I do think this is a driver issue, as this configuration works fine in single cards, Nvidia, AMD, Intel, or in SLI mode (with Nvidia cards, confirmed on 2xGTX285 ).

The workaround is just to use Shader Complexity 7 (or less) to get around this problem on AMD Crossfire configuration.

I'm working on solving this issue. It might take some time, as i cannot reproduce it yet personally.

OCCT 4.2.0 Available

This version marks the release of OCCT Pro and OCCT Live.

For more information, check our software page !

Changelog : OCCT

BugFixes :
  • The Idle period boxes (among others) should now stay disabled after an infinite test
  • Test processes should now end all the time when the main GUI is closed during a test
  • Avoided a rare case where a test would be reported as "in error" and immediatly reported as "testing", even if stopped (the error and graphs were correctly generated though). THe status label was updated one extra time. Occured very rarely.

Translation :

  • Added Romanian, Russian and Japanese translations

Changelog : OCCT Pro

Initial release

Changelog : OCCT Live

Initial release

New Website !

Finally, the old website has been replaced by this new one, to better reflect all the work that has been done around OCCT along these three years, and the release of OCCT Pro and Live !

We decided to put it online without the discussion boards being ready. It should be available soon ! Stay tuned :)

OCCT 4.1.0 Available !

This version introduces a brand new GPU:3D Test, completely rewritten in DirectX10.

Linpack has also been updated and now includes an AVX-capable version. If your CPU supports AVX, the AVX version will be better. If not, untick the box for better performance.

Changelog : OCCT

  • Revamped the test scheduler - allows more flexible auto tests
  • Added an very small and lightweight update checker that will warn you once when a new version has been released.
  • Revamped the UI slightly : tabs are now on top of the tests, system info remade
  • Main window cannot be out of bounds when loaded - sorry
  • The ON button doesn't blink anymore - the status label will.
  • The FPS graph will continuously refresh
  • New icon (that's the feature everyone was waiting for, i know)
  • Now has 2 versions : AVX-capable and the older one (from 3.1.0). Use the AVX version on AVX-capable CPUs, and the other one if not, for better results.
  • Brand new test supporting DirectX10 ! Much more efficient, better at error checking... requires Windows Vista or Seven (out of the box - DX updated issues are gone with it).
  • Updated
  • Now carried over from version to version

Enjoy !
