the problem is essentially their game design, not a version – randomly generated levels are completely random with enemies and items spawning inside walls, and since they cant have ai pathfinding in a random mess they generate enemies have to teleport in a crow particles to you and then try to fight in a prefab mess they scattered. Animations and movement is not polished in themselves since its not a big aaa studio and combined with random placement map part jank it just multiplies.
I managed to get it to run at 90 with some ue tweaks in config files and it runs in dx11, well Im using launch parameters to make sure it does because there are only 2 dx12 profiles: cyberpunk and game-that-we-cant-speak-of so essentially just cyberpunk and it doesnt have g3d or z3d in dream cycle even though it hooks.
