I am playing the latest version of the game. The lags happened when i was in the battles, the fps on the left hand corner shows that there are only 25~35 fps, but normally my laptop can handle csgo around 90 fps, i don't know why. When it is around 60 fps, i feel like that 'man how can the weapon load that fast and smooth' so if you have time please check or optimize it, thanks
