So, I used to play some games under OSX and it seem to run pretty well. I played through a good chunk of Portal 2 and could get it running well enough for my liking. I downloaded Dungeon Defenders the other night for OSX and it was running absolutely horribly. So I turned the graphics options down to low and set the resolution to 800 x 600, and it was the same mess. I thought that was weird, so I tried Left 4 Dead 2 and Portal 2. They ran very poorly. My next step was to install Dungeon Defenders in Windows 7 (boot camp, dual boot). I can run it on "high" graphics at 1280 x 800. Just installing Portal 2 to check it out.
I know OSX's OpenGL performance is not great relative to DirectX performance in Windows for pretty much every game, but it wasn't this much worse before. I can't figure out if it was the OS upgrade to Lion that did me in, or what. Any recommendations on what I can do to try to fix this, short of a reinstall? If I were to reinstall, can I create a Lion disc from the App store, or do I have to install from my Snow Leopard disc and then do the Lion upgrade from App Store?
My laptop does seem to have a particularly bad heat problem. In Windows it'll shut itself off if I run a game. Is it possible OSX is doing some kind of dynamic under-clock adjustment to keep itself from frying? Seems unlikely, but I've never seen my Mac get so hot that it shut down under OSX.
