Kind of a weird one, unfortunately I have not had a chance to attempt a repro.
Both Photo AI and Video Enhance AI were VERY slow even with GPU selected. I was getting 0.1 fps with progressive video enhancement at 1080p and several seconds for denoise on a 3mp picture. GPU load on gpu-z showed about 5% utilization. I tried reinstalling which made no difference. I’ve also tried switching between CPU and GPU several times. Other applications (handbrake, games, etc) had no issues utilizing the GPU.
Ah! I actually found a bug I think. From the logs of PhotoAI:

Note that I have already detached the the integrated graphics at this point and disabled it in BIOS. At this point, the igpu is disabled and unavailable. It looks like OpenCL maintains a GPU even after it has been disconnected and will reorder devices on connect (why Intel why??)
It looks like there is a disagreement for the indices between Topaz and OpenCL. 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. 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. 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.
On a side note, I’m wondering what would happen if the user selected GPU, then enables the iGPU. Would Topaz correctly update its device selection in the registry? Or would it end up defaulting to the iGPU because of the reordering quirk?
With this I think I have the full repro:
Have a machine with Intel CPU and Intel GPU. Make sure Intel drivers are not installed.
Make sure the iGPU is disabled then boot the machine.
Install all necessary drivers.
Enable the iGPU.
Disable the iGPU.
Topaz should now be stuck in CPU only mode now.
Use registry hack and manually set to the correct device id.
Re-enable the iGPU and select the correct GPU in the menu.
Ok more updates lmao. So the second workaround doesn’t work. Topaz is just not using the correct indices:

Notice that A770 is listed at index 0 in the first log snippet, but is actually at index 1 in the second log snippet. :((( Clearing the registry does not help, so I’m guessing a bad assumption was made somewhere. Guess there’s just the registry hack left.
I have seen in other posts that for the Intel ARC770 you need to disable the REBAR parameter from the BIOS. Try that to see if it improves, note that if you are gaming as well, you will need to enable it for gaming.
I am not sure what the effect is if you are using a iGPU though.
Copy the files from runtime/bin/intel64/Release into the root directory of Topaz. (e.g.: C:\Program Files\Topaz Photo AI)
It should ask you to confirm whether or not you’d like to replace the files. After that everything should work as expected. I still find it strange that benchmark software passmark still works. Maybe they don’t use OpenVino ¯\ (ツ) /¯
Hello, back again! I missed one thing which causes issues with Photo’s sharpening and probably causes the unknown error in VEAI. Unfortunately I can’t edit the post anymore…
Rename openvino_tensorflow_frontend.dll from the downloaded Vino toolkit to openvino_tensorflow_fe.dll This should replace the existing openvino_tensorflow_fe.dll.
As for the video, I’ve noticed some failures too… I get a blackscreen then failure occasionally when I’m using the GPU for something else (e.g.: watching a VLC video). Unfortunately I don’t use VEAI as much as I do the Photo AI so there might be some combination that I don’t know about. I’ll try running a longer clip through VEAI tonight and report back if it succeeds
Edit: things like youtube also use the GPU. One option is to disable hardware acceleration in Chrome. Kinda sucks that we have to jump through these hoops but that’s what we get for trying something new
Edit 2: Woohooo! I got a video to finish exporting. Set the max processes to 1. It looks like there’s some funniness going on with having multiple GPU processes running at the same time. Maybe some context switching bug?
Sorta success… I get unknown error with motion deblur and stabilization turned on. Normal video enhance seems to work ok on the two videos I’ve tested it on. I guess we’ll just have to wait for Topaz to fix the issues.
