Would Topaz correctly update its device selection in the registry? Or would it end up defaulting to the iGPU because of the reordering quirk? On a side note, I’m wondering what would happen if the user selected GPU, then enables the iGPU. I’m guessing the fix on Topaz’ end would be to grab the device index from OpenCL instead of implicitly relying on the ordering for id. I confirmed this is the case by manually setting the deviceId key in the registry to 0x01 and PhotoAI was able to use my GPU. My guess is that Topaz lists the list of available devices and assumes that whatever index they get from the the list will match OpenCL’s device enumeration. It looks like there is a disagreement for the indices between Topaz and OpenCL. It looks like OpenCL maintains a GPU even after it has been disconnected and will reorder devices on connect (why Intel why?) At this point, the igpu is disabled and unavailable. Note that I have already detached the the integrated graphics at this point and disabled it in BIOS.

I actually found a bug I think. **** Problem already manifested after these two steps **** I switched from hdmi output on my GPU to displayport.= Dev repro hints underneath =įrom my memory, I did a few things which might have caused this: Hopefully this will help anyone in a similar situation! I got the hint to delete the registry keys from the Topaz CLI documentation. Everything worked after that and I was getting 11+fps with much better GPU utilization. Other applications (handbrake, games, etc) had no issues utilizing the GPU.Ĭomputer\HKEY_CURRENT_USER\SOFTWARE\Topaz Labs LLC I’ve also tried switching between CPU and GPU several times. I tried reinstalling which made no difference. GPU load on gpu-z showed about 5% utilization. I was getting 0.1 fps with progressive video enhancement at 1080p and several seconds for denoise on a 3mp picture. Kind of a weird one, unfortunately I have not had a chance to attempt a repro.īoth Photo AI and Video Enhance AI were VERY slow even with GPU selected.
