Are you playing on the lowest graphic settings and windowed?
Wouldn't windowed make it worse. Even if it's slightly, every bit helps. Because iirc when you're in a fullscreen game, it's only rendering required processes in the background, and the fullscreen game. Where in windowed, it's still working on everything. I'm not too sure if that's how it works, but I noticed my games lag more/lag in less graphical intense situations when windowed.
