During my traipse through the cosmos, I had to fight on a lava world. Which sucked because I left my air con at home. When I loaded into the game, it lagged horribly, I didn't have a counter up but I'm sure it was below 10 FPS. Zoomed in it was better, but on a planet-wide view it was horrendous. After about 30 seconds to a minute it evened out to a perfectly playable framerate, and I didn't have any trouble throughout the match. But the beginning was clunkier than a grandfather clock made of rusted metal. It's worth noting this didn't happen on any previous planets, but all previous planets were metal and one desert (sadly lacking in giant sandworms).
