In case someone finds this post somehow, I ended up using Lightworks instead and it works fine for now. Couldn't get Resolve working, on Linux at least.
I have the same card and have no issues (have had the card for a year). I suspect something else is going on.
Might be, do you use Windows?
Yes, windows 11 but before that win 10. Are you able to check your gpu in task man while you are running (you can see memory usage).
Are you by any chance doing a lot of compositing in fusion or just straight editing?
Edit: also which version of Resolve are you on?
Version 18.6
It jumps between that and 214mb. You're probably right in not being the hardware because the usage almost definitely didn't suddenly spike that high 2 seconds after the program opens. I'll try it on Windows and see if that works. Might also be me installing it from the AUR instad of the official release.
And no I'm not doing any intense editing, I just imported a video file. It's 29 gigabytes but again the memory usage was way lower than I expected.
Ok. If you're working with 4k or 8k footage you probably want to start working with proxies instead of directly. It's very easy to set up in Resolve.
Use software rendering?
