The game seemed to run just fine, but shots and explosions where rendered incorrectly (2D bitmaps superimposed over the 3D background, probably represented as “particles” in the engine): It looked like Z-buffering rules were switched. What should be hidden behind scenery was shown and what should be shown was hidden. This made it kind of hard since I couldn’t see neither my own nor the enemy’s shots (until after they hit something and where partially behind things…). Could it be this is due to some OpenGL-extension you are using that isn’t supported in the Mesa + 3dfx implementation?
