I am getting this very bad stuttering in all of my source games (HL2, TF2, CSGO, etc.) and I cannot seem to find the cause. What it does is, the game will run fine for around five minutes and then out of nowhere, the game freezes and goes back to normal within a second, but this can absolutely destroy you in competitive games like CSGO. I have gotten a new GPU recently and it is still happening so we can rule that out. I have tried uninstalling and reinstalling, I have tried what every single person on the internet has suggested to run in fullscreen mode and I have tried lowering my settings all the way to low and it is still happening. I am not entirely sure what my next step should be but any help would be appreciated. Knowing me it will be someone responding with a simple fix like "change this slider" and I'll feel like an idiot ahaha. Thanks for any help guys! You're all awesome!
