Topaz preferring iGPU instead of 4090

Topaz Video AI General
1

I’m using Video Enhance on some pretty beefy 8K EXR footage (also writing EXR) and I have close to 0 fps. This is on a Windows machine with latest Nvidia studio drivers and a 4090. But for some reason, even selecting the 4090 in Windows graphics preferences and the dropdown within Topaz, Topaz is still hammering the terrible on board intel GPU. Has anyone seen this? How do I force Topaz to totally ignore the on board GPU and use my 4090 more than 30 percent.

You can disable the iGPU. Not sure how much that will change the usage percentage of the 4090.

How?

But I do think I solved the issue by changing the AI processor inside Topaz from the 4090 to Auto. When set to Auto, it weirdly uses the 4090. When set to 4090, it uses the iGPU…

The iGPU can be deactivated in the BIOS. :slight_smile:
