when playing the game freezes and then will unfreeze but stutter constantly from that point on until a crash to desktop.

am i missing something? i'm standing in front of the wheel but no prompts show and no input seems to work anywhere.

when kill boss i cannot join for next lvl

Does the refresh rate of game got better after the release? I played the demo, i really liked the game, but something was wrong for me. Sometimes i had the feeling that the game was blurred, but after seeing some videos i've found that the engine refresh rate is low and that was causing me some nausea. When you move the char up, down or to the sides but looking at the cenario you can see clearly that something is wrong. And many time we have a huge FPS drops too. It was fixed in the game already?...
