Hey.. so a while ago my entire PC started feeling laggy. Both in games, and on my desktop.
I play a game called Osu. I play it in windowed mode with an average of 600-800 FPS. But I can easily see that it's NOT running at 600 FPS. It feels like it's running at 25-35 FPS. I tried setting it to fullscreen and it worked. The lag was gone.. so I tested it in a few other games..
I tested it in Team Fortress 2 and it was laggy. Tried changing my video settings but it was still laggy. I tested some other games as well but it was all the same.
Now whenever I move my cursor around on my desktop or in Firefox / Chrome, I notice that it's 'laggy' as if it has low FPS. It's definitely not moving very smoothly.
These are my specs: http://puu.sh/az9X4/cad82d07b6.png
It's NOT overheating. So please don't ask / say anything about it. It's the one thing I'm 100% sure about. It's definitely not overheating. It doesn't matter how warm / cold my laptop is. It's always the same
So, basically.. I have high FPS in games but it still feels like I have low FPS. Even on my desktop or in a browser.
