You're stupid if you prefer a choppy 20fps to a silky smooth 60fps.
I don't really have a good hardware to be able to reach that on
some most of my
games. Not to mention being online status on Steam forgets up a lot of my FPS, if I go offline, even when my game is open (Alt+tab), the game fixes up the FPS.
Terraria is lagging a lot thanks to Steam, however, I can run it fine as long as I don't have Steam community online. And this happens with ALL games I run on Steam.
I have no fault onto that.
