It runs like that on every PC. RenPy is not really meant to be used for combat systems.
i see thanks but i noticed few things the 32bit version is less laggy maybe? also put 30 fps as cap also forcing it to ANGLE2 RENDERER and enable tearing actually helps also makes sure not to play in full screen i was able to play with decent or at least a lot lesser lag cus of it just saying it here so if anyone else have this problem they might find it helpful
