I would like to ask some optimizing to new renderer. Now it gives only 10-20 fps on my trium map01, you would say it's big, but no! it is highly optimized, there are <10lights in screen (4-6 average) and <400 linedefs in screen wherever you look. I will post screenshots in trium topic a bit latter, there you should see the places i say and fps counter =( May be that's possible not to count shadows over the radius of each light, or count traced vertices for each light and morph shadows somehow?
