Im having a really weird issue with this game, everytime i close it my computer turns really slow for a few minutes and then it feels like its gone but when trying to execute other programs or opening the browser it seems to be slow aswell. It has happened multitple times that after closing, i get constant stutters in super low requirement games like League of legends, and as said, it only happens if i did play Insurgency and then closed it, otherwise every other game runs smoothly like always.

My hardware is:
GTX 1060 6gb
Ryzen 5 1600
16gb ram 3200mhz
