Hello guys, so the game is poorly optimized and the graphics isn't working properly. So when i turn on vsync the game is slowmo so to speedup i have to decresase the rendering quality very low then the game speeds up. So if u want vsync u have to decrease the rendering quality and put all graphics on low.
The other method which worked is turning off vsync and tuning the frame limit until the game get smoother. One thing I noticed is u have to put the frame limit less than ur screen fresh rate otherwise it will lag.
I hope this works so I would like to know how it worked.
