GPU working in Photoshop CS6 x32 but not x64
Dear forum,
I am having trouble to activate GPU-support in Photoshop CS6 x64. I recently changed my GPU to an Nvidia Quadro 4000, running on a Windows 10 x64 machine. I installed the most recent drivers (tried both ODE and QNF drivers) but I cannot get GPU support working. All other CS6 components activate GPU support without any hiccup (AEX, PPro) even Photoshop x32 works flawlessly. I need to activate the 10-Bit feature for a wide gamut monitor.
The strange thing is that I have a similar machine (same mainboard, same ram, same GPU, same SSD aso) with Windows 10 x64 which does not show this behaviour.
Has anyone suggestions what to try? What I tried so far:
1. different driver versions for Quadro 4000 (375, 372, 341, 311)
2. reinstalling complete CS6 Production Premium
3. turning off sniffer_gpu.exe (by renaming it) for PS x64 which actually makes the option for gpu support available, but still does not use it (still 8 bit display-depth instead of 10 bit)
Any help is much appreciated!
Regards,
Silvan
