Few days ago I did the weekly system update which included latest NVIDIA drivers. Everything went smoothly, no error messages, systems works as usual. Today I wanted to play some game and I noticed that the performance was horrible. This is what I found
I've tried to reinstall drivers, and ran some fixes I found online but still no luck. Any ideas how to fix it?
update
Just remembered. After last drivers update I wasn't able to run any Steam game. I always got some directx error. Before I had no issues.
update 2
I'm on Fedora 40, currently I'm using drivers downloaded directly from NVIDIA website. Before that I was using whatever drivers from these repositories
Did I understand it right that you installed the driver manually? It's generally better to use the Fedora Nvidia driver package (sudo dnf install akmod-nvidia), than to download from Nvidia's website. I'm on Fedora 40 too, and currently using the 560.35.03 version of the driver on a 2080, which upgraded from 555 recently - I wonder if that's what broke compatibility with your version of the driver. It may be that you need to update. Only thing I'm not sure of is how this will interact with manually-installed drivers...
This is what you should be using on Fedora. Though take note, after each kernel update, you need to allow the module some time to rebuild, then reboot to ensure it got loaded properly.
Try running:
'dnf reinstall kernel-modules'
then reboot. This will trigger a cascading rebuild of the kernel modules that get rebuilt on every kernel update.
It didn't work. At this point I'm considering nuking the whole thing and start with the fresh system. If it won't work I will buy a Windows PC just for gaming.
Well then follow every single guide online that is telling you exactly what people here are telling you. Remove every single Nvidia package, disable secure boot, then reinstall.
