I get 2 fps in windowed mode

I can play 1920x1080 with no problems, but windowed mode in any resolution slows my game down to the point where I can't even join a game, much less play one.

I bet your desktop is in 32-bit mode with loads of things like Windows Aero interfaces activated. I had that on a friend's PC - knocked it down to a 16-bit mode, no visible difference and worked much faster.

Windowed mode will always be slower than fullscreen mode on any application. If your desktop is 32-bit with Aero and a rubbish graphics card/driver that's another performance hit. Also make sure it has focus (i.e. click on the window) because background windowed apps have a pitiful priority.

And Altitude uses a library that I, too, have seen suffer in non-focused windowed mode quite heavily even on powerful machines. Giving focus stops the problem (it looks like the game runs at the same speed, but the screen isn't updated anywhere near as often as it should be if the app is in the background).

My desktop is 64 bit, with quad core p4s and 4gb RAM, but kind of a ****ty graphics card. I disabled Aero and am using the windows 7 basic theme, but the problem persists. Advice?

Nevermind, it looks like disabling aero fixed the problem. Thanks dude.
