Bad graphics and performance with AMD (RX7800XT and R5 7600X)

I can't get the graphics to stay good and the fps on planets maxes-out to around 70 but usually stays around 50. When I turn on Vsync, the fps snaps to 30. The fps doesn't change depending on the settings (Low vs. Extreme graphics). Another problem is the textures become blurry around 1min upon entering the game, and looking around sometimes causes everything to become pixelated in split second intervals. If I turn on raytracing even on low it causes major blur and artifacts on the screen. (Although idk if the RX7800XT is any capable of raytracing). I think the problem with the textures can be seen in my pictures of the trees. I think the problem is they switch to low texture variants when going far away from them, but they don't switch back to high texture ones when getting close. Switching Anti-Aliasing from FSR to FXAA/OFF sometimes turns the game into a pixel mess looking like a blurry 8bit game (couldn't get it to happen to take a screenshot).

Also my CPU and GPU both keep running at 95-99% usage with my CPU staying at temps around 90 C! I feel like with my hardware this game should at least be running at ~100-120fps with lower temps and usage, no?

Early alpha, I understand, but having that high temps prevents me for playing the game for long periods. GPU: RX 7800 XT CPU: Ryzen 5 7600X RAM: 32GB DDR5 Adrenaline is up-to-date as of writing this. EDIT: Also I run @1440p on a 165Hz monitor, and I forgot to mention, the fps is not smooth it keeps having micro stutters at any setting.
