I tried playing your map, but the game crashes and I get this error: "Z_Malloc: failed on allocation of 16777240 bytes from the main zone"

I've been contemplating making this single-player map for the Hunt mod that would have bot support in it. The reason I would opt for HUNT and not EntityPlus for this specific idea I have is that I want it to be cooperative.
Also it's not really about having the latest hardware, it's more of a crusty old engine showing its poor scaleablity for them (given the GL 1.1 fallbacks and a lot of software processing for all the light calcs etc), and taking a few regressions (particularly compiled vertex arrays not being detected, needing r_primitives 2 to be explicitly set to regain speed). In theory, a typical Geforce2 would be fine with this map.
and of course the playerbase that "need" 333fps to gain the physics exploit advantages causing the big complacent gaming divide since 2002, where "r_vertexLight 1 r_picmip 32 is the way to play". that send all possible artistic visions to hell just for the win. Geocomp changing mapping ideals especially didn't help matters....
