Graphics and Frame Generation

Hey there guys, quick question... When I move my camera a little faster the game drops in quality to an absurd degree. I have a good graphics card (7900XTX) and I can't figure out how to stop it. (It's I'm the video, sorry that I had to record with my phone)

Also, when I use the frame generation option (FSR3) the game tends to freeze a bit, why is that ??
