Hello, my friend has a big problem with his PC. He has stuttering in every single game he plays. The only thing that reduce the stuttering is turning on the V-Sync. I looked up on internet multiple times and never found a clear answer to the problem or even just a fix. He sent back his PC where he bought to have it check by a technician since he have a warranty. But they said that the PC was fine and that there was no problem at all. To explain what it does in-game, the game freezes for a second or two every 15 to 30 seconds. We took a look at the temperature while in game and everything was fine. I actually have no idea what the problem is and i'm kinda pissed of because it makes it unplayable for the 3/4 of the game. So I can't play the game I want with him. If anyone had an issue like that before and eventually found a fix, it would be nice to share it with me.
