Confirming. I’ve bought V12 and it crash all the time when using GPU, when tuning CUDA support OFF everything works FINE. I can say, that on the same NVIDIA drivers 306.23 [on Windows 7×64 with all updates] under CS6 [Premier / AfterEffects] GPU/CUDA rendering works FINE so I’m sure that the problem is in some code-lines from SONY not from NVIDIA. SONY PLEASE make some UPDATE on that. I,ve got i7 XEON 4,2 GHz on CORE [x4] multitasking OFF – and any way I can feel the difference with and without CUDA when rendering ;/ Under Vegas 11 on the same drivers everything worked fine. GOD, HAVE MERCY FOR VIDEO EDITORS 🙂
