Requirements
A3dQuake will in general, run on any platform that glQuake will run on. I have only tested on and provided binaries for Windows, but there is no new platform specific code.
Performance information is sketchy at this stage. The tests that have been performed show that if the systems open-gl acceleration is sufficient, then the performance penalty could be as little as 25% ( even though open-gl is drawing twice as many triangles). Hardware that dose not accelerate the correct functions, or is inefficient in this acceleration with be much worse, up to 15 times slower or more in some cases.
The manual contains a list of tested systems and estimates of there performance.
A3DQuake Only requires one more function than regular glQuake, glColorMask. Unfortunately I suspect that a lot of consumer 3D cards do not implement this (or alternatively, I have used it wrong ). I have found this to work as expected in fully software emulated open-gl and on the TNT2, but no others (so far). Open-GL to Direct3D mapper's and mini Open-gl systems do not work, because they implement only the features commonly used.
