Recent delays in contact emails - Sorry !

As announced on Twitter, i am now the proud father of twins since June, which take up most of my free time, the rest being almost entirely taken by my work which has been really busy lately. I knew it was hard being a father, but i never expected that taking care of twins would be as time consuming (and such a happy time as well ! ).

As of now, i am about 2 months behind in answering my contact emails. I'm putting the customer support email a top priority (expect an answer in less than a day), as well as in sending purchases of OCCT Pro (Usually sent the day after the payment has been confirmed by paypal).

I really want to apologize to all of you who are waiting for an answer on my side - i'm really doing my best.

I'm planning of taking a entire day off work to answer all those emails and answer topics on the forums too. It will also be devoted to working on OCCT's next version, which will probably be a minor update, before the big changes i have in mind for the next major version. It is really hard for me to announce a day yet, but stay tuned !

OCCT Pro licensing updated, OCCT Live discontinued

OCCT Pro and Live version are evolving to be in sync with what the professional users expect.


OCCT Pro is now priced at 150$ per year and the license is tied to a USB Disk drive. OCCT Pro will start as long as the USB Disk drive is plugged in the computer.

For our previous customers of OCCT Pro, the previous licensing system will continue as long as the licence is renewed. We will contact all our previous customers and send them the new license file that is required for OCCT Pro 4.4.0.


OCCT Live, due to the general lack of interest, is thus discontinued.

OCCT 4.3.2, GPU:3D and Windows 8 issue

A serious problem has been found with GPU:3D and Windows 8, as it will crash upon startup. The root cause of this problem narrows down to the OS, as Microsoft seems to have completely broken the compatibility of DirectX10 with Windows 8.

I am planning two things regarding this issue : first, try to get a DirectX10 version running quickly, and then move on to DirectX11, as sticking with DirectX10 has no added value now that i have to use an updated SDK, and force dxwebsetup.exe to be run.

I'm currently working heavily on it, and hope to have a new beta out soon.

Meanwhile, you can use the DirectX9 test, which works under Windows 8.
