I have two GPUs installed in my computer. A NVIDIA RTX 4090 and a NVIDIA RTX 5070Ti.
If I go into Topaz Labs preferences and change the processing GPU to the RTX 5070Ti, then try to render a video with the Starlight model, all processing will occur on the RTX 4090.
This issue does not occur for non-starlight models.
Sorry for the delay here, got lost in the shuffle. Feel free to always email us at help@topazlabs.com for faster support. From the logs, it appears that the 4090 is selected. Can you try saving, closing, and reopening the app to see if that helps the setting adhere?
If you’re still running into this issue, please email us!
