Lagging of games

[ankitmane11]

I had recently installed Ubuntu and then again uninstalled it. My games like fifa18 cs go are now lagging.
Ram: 8gb
Graphics card: NVIDIA GEFORCE 4gb
Processor: i7

If you reinstalled windows after you uninstalled Ubuntu then you probably need to install your drivers. Motherbd chipset first, then the gpu drivers, followed by the rest of the motherbd drivers.
