update: ayo i noticed that its bcuz the game aint hittin 30fps, so make sure ur game runs stable. if u got motion blur activated, disable it, it causes a LOT (and i mean a LOT) of lag
same goes for me ;c i really want to pay with paysafecard but idk if that works cuz i cant find the pay methods and i searched at steam for the game and i was so sad when i saw that only the part 5 is available :(
