I tried the Motion reprojection - and by the way it is indeed very helpful and runs super - with the rx 570 and the GTX 1060 and had no Problems at all. But since i installed the rx 5700 I'm not able to enable this again. I tried to install wmr new (completely new because i setted up the Computer newly), i reinstalled the latest Driver (with this Driver it worked properly with 570 and 1060). I don't know further anymore…. If anyone can help me, so please just do it, thanks!
