Topic: SVP can't detect Nvidia GPU on Windows 10

Just installed SVP on my system (i7-6700HQ, 960M) and the only GPU it detects is the integrated graphics (Intel HD graphics 530), not the 960M. I thought it might be my drivers, but I did a clean install of the Nvidia drivers after removing the old drivers in safe mode with DDU and it still won't detect. I have all power-saving settings disabled or set to use max power, and Nvidia Control Panel set to always use the 960M by default. I'm using the latest version of SVP 4 Free for 64-bit Windows 10. The 960M is working perfectly in all other programs/games

I'm out of ideas. What else could be causing this? Is there any special software/codecs to use or specific settings to choose when installing SVP?

Re: SVP can't detect Nvidia GPU on Windows 10

To get discrete GPU working you need to have OpenCL driver properly installed. It is part of NVIDIA GPU driver.

You can get current state it with CLinfo:
SVP tray menu - Information - Additional information - OpenCL devices and compatibilities.
Paste output here.

It only seems to give information on the Intel device.

Re: SVP can't detect Nvidia GPU on Windows 10

And the old Nvidia 375 driver was properly removed, and current driver 376.09 was correctly installed

Re: SVP can't detect Nvidia GPU on Windows 10

have no idea then...

it could be an Optimus issue, however I don't have optimus-enabled laptop in hands

do you see "nvcuda.dll" in NV control panel -> system information -> components?

Re: SVP can't detect Nvidia GPU on Windows 10

Yes.

NVCUDA.DLL
File Version: 6.14.13.7609
Product Name: NVIDIA CUDA 8.0.0

Re: SVP can't detect Nvidia GPU on Windows 10

I have an external GPU I can connect via Thunderbolt to see if that is detected w/o Optimus (connecting monitor directly to GPU)

I'll give that a try

Re: SVP can't detect Nvidia GPU on Windows 10

> I have an external GPU I can connect via Thunderbolt

that's cool smile

Re: SVP can't detect Nvidia GPU on Windows 10

It's worth nothing that the performance of the Intel GPU should be plenty fast enough for SVP unless you're running with 5x interpolation and MadVR* or something.

*if you do use MadVR, it's typically a better idea to set MadVR to use your discrete GPU while SVP uses your integrated GPU

Re: SVP can't detect Nvidia GPU on Windows 10

for example, Intel 530 is NOT enough for SVP @60 fps + "opengl-hq" preset in mpv

Does mpv let you select which GPU to use like madVR does?
