i try to keep it short: i have issues with some games (like the witcher 3) and often hear that its an issue with nvidia drivers etc…
So my question is: would a switch / small upgrade to a AMD Radeon 6800 be worth it?


Switching might not fix your issues, and might just be swapping for other issues.
Ive been running Nvidia with Linux for over 10 years and its improved significantly over that time. Around the time the 30xx series came out I was looking to upgrade from my 1080ti - I wanted to switch to AMD (because I heard the drivers are better) I got a 6900XT and had heaps of problems and even worse performance in some games than my 1080ti. I ended up returning it and got a 3070ti instead, and I had no problems and performance was great.
About a month ago I wanted to upgrade my 3070ti and give AMD another shot with a 9070XT - its been absolutely flawless this time around.
All this is to say there are no guarantees going AMD will solve your problems, but I would consider going an AMD 9070 series instead - particularly since their FSR Redstone thing only applies to the latest cards
This sounds like driver clash. 6900xt will walk all over a 1080ti. 9070xt is good but for the price you can get a 7900xt much cheaper and gain vram over 1 to 15 frames.
No, it wasn’t a driver clash. I tried a lot of things including downloading the pro drivers that were also recommended on trying. At the time, there was a problem with AMD cards and CryEngine games performing badly.
Interesting. Usually AMD gets better with age and stability is much better than Nvidia. Although raw hardware performance Nvidia usually wins but the headaches usually aren’t worth it when you play little of everything especially indie games on steam. IMO.
My Main thought is, that i dont wanna spend sooo much money, idea was buy a used one, sell my nvidia. Would be around a 50€ upgrade.
