rx 6000 performance issues

[[GH]Cody]

After the last 17d update the ground textures are finally back to normal! The only drawback currently still seems to be performance issues with the rx6000 cards specifically in multiplayer. I have a 6800xt. For reference playing round 3 of the Ariel SX tracks by myself my framerate is pushing 130+. When I go into multiplayer my framerate dropped to below 15 during the start of the gate drop till slightly after the first turn. During the race my framerate was regularly going under 40 and being spiky making it feel very jittery. This was with roughly 10-14 people during the race. The less people close together the better the framerate.
