Mouse lag in fullscreen renpy games

[PTdaddy]

Hey F95 lovers,

My PC power supply broke down and after upgrade with a new one and now i have terrible mouse lag in fullscreen renpy games (in window mode no problems)
I have NO clue what to do to solve this problem.
I have a good pc and never had this problem before.
i7, 16 mb ram and Nvidea GTX 1060 6GB, so that's not the problem.
HELP, it's really annoying

Hello May this can work : right-clicking on the game, selecting Properties -> Compability and checking "Disable Display Scaling On High DPI".
