GPU Rendering/Acceleration is disabled in Premiere Pro CS5 after GPU upgrade.

[Rod31650573qg4x]

I've just upgraded my GPU from an RTX 2070 to an RTX 4080 Super, but now I can't enable GPU acceleration. It's an Nvidia GPU with 10,240 CUDA cores, so I don't know why I wouldn't be able to use Mercury Engine GPU Acceleration with this card. Is there some step I have to do beforehand to enable it?

Which version of Premiere are you using?

CS5

Wow, that's ... ancient!

I belive the CS versions had a GPU file, and the GPU name needed to be listed on that file. So you would need to find that file, and try to add the name.

Although I'm not certain that CS5 can use a new GPU that different from what the code was back then.

You were absolutely right, thank you. I followed the instructions in this video, and it worked: https://www.youtube.com/watch?v=k6KFkHUytYQ

Just in case that video ever goes down or gets lost, I first went into `Program Files\Adobe\Adobe Premiere Pro CS5` and opened a file called "cuda_supported_cards.txt"

I opened the command prompt and navigated to that same directory, then ran "GPUSniffer.exe"

I took the exact name of the GPU reported by the sniffer in the screenshot above and then added it to the text file.

And that's it.

I am both glad and amazed that card works in that version! Happy working!
