when playing some levels on MOHAA the games runs smoothly but then on other levels it becomes jerky with a low fps rate, im running the game on the lowest settings, i have a nvidia creative Geforce 2 MX 400 32mb card (with the latest drivers) on a 500 mhz AMD k6 3d processer with 312 mb of RAM, its even worse on spearhead where the fps is even worse also on the lowest settings
