When I first tried the game out, I used OpenGL. I wanted to get some radioactives from Mercury, but to my horror the landing there caused the game to run at about 0.2 fps (that's right - one frame in 5 seconds), and become extremely unresponsive. Naturally, this means quick death on mercury. I tried it again on pluto, and the same problem was there. However, once I get the lander back up (couldn't steer well enough to hit the Spathi ship! ) the game went back to normal. Even the landing/takeoff animations for the lander were at a high framerate. This problem does not occur with space battles (at least in super melee - didn't get to check out the in-game battles with OpenGL). Using SDL instead fixes this, but makes the average framerate slightly (and annoyingly) lower.

If it wasn't for fog, the world would run at a really crappy framerate.
