Topic: NVidia GPU, awful FPS & no GPU Acceleration?

I recently switched back to a Nvidia GTX 970 from my Radeon R7 260x.   

Using my paid copy of SVP 4, I now get much worse performance than I did when using the far weaker R7 GPU.   SVP does not list the Nvidia GPU as available for acceleration or transcoding, and in opencl.log reports:

Number of platforms                               0

Weirdly, I used to use paid SVP with the 970 last year and it worked well. 

What's going on with this?

Reinstall NVIDIA drivers with Clean install options.

If it will not help you then use Display Driver Uninstaller to completey remove all Intel/AMD/NVIDIA drivers before install NVIDIA again.

DDU + installing 417.71 drivers & enabling GPU Accel appears to have fixed the issue.

BTW, should I be using this "Optimize for Compute Performance" option in the Nvidia Control Panel when running SVP?

Looks like it must give you some performance growth.
What does the setting "Optimize for Compute Performance" do?

But we are not tested it. You can check it and tell us if this setting have effect in your case wink
I think GTX 970 is more than enough for SVP calculations. Take a look to GPU load.
