At my preferred settings (ultra -bloom) tdem demo1 gives me an average of 122fps, why do these maps differ so much? Disabling realtime shadows & reducing the resolution also provides little improvement (+5fps, which doesn't suggest a hardware limit) on these maps.
Strangly players running Windows don't seem to notice the lack of performance on these maps, is it only Linux that suffers with these?
My specs:
E6300 @ 3.15GHz
BFG 7950GT512 @ 650, 1550
Corsair XMS2 2x512MB 5400C4 @ 900MHz, 4-4-4-12

PS. Running Nexuiz 2.3 x64, was also the same on 2.2.3 x32.
