Hey guys! I have the same problem with csgo. When I move my mouse to aim or smth like that then fps drops and i get lag spikes and stuff. I have Logitech G402 and my specs should be fine. They are quite humble - I5 4th gen and GTX 1050. If I set the polling rate to 250 or smth then its fine and dont have problems but id like to play at 500. Does somebody have solutions? I know my English isn't good but still i'm lookin for anwsers.
