I haven't been working much on SDQ lately, but i just tried out MH's DirectQ engine, and it works flawlessly. Faster than my engine and definitely Darkplaces. Mhquake.blogspot.com Extract to your main quake directory, and run directq.exe -game sdquake. i ran Larger Room, with about 1000 monsters in one room and there was hardly ANY SLOWDOWN. Nice!!!
