Matrox G400 Max, Intel PIII CuMine 600 MHz, 512 MB RAM... this system runs Rune @ 1024x768x32 fluently but is choppy with Vavoom 1.13 Win @ 640x480x32. In OpenGL it's somewhat less choppy than in Direct3D, but it is nevertheless. What settings could help here? Is there a timedemo or fps counter so I can say what fps this choppiness actually consists of?
