Error CohogRender / GPU work request failed

cortex bug
1

I need Cortex for Dead Pixel Detection and tried to check X-OCN footage what resulted in an error.
Checking log files showed an issue with GPU rendering via CohogRender.

CPU work request failed: Initialize failed, returned 2

I use dual GTX 760 - tried with only one, in SLI and without - nothing worked.

Is there any incompatibility with older cards?

Hi Patrick,

Can you make sure the GPU driver is up to date?

It’s January Release 417.71 - must be the most recent
