DanpixedI've never seen this before, can you provide a screenshot?
This is probably what he is talking about, doesn't lag me but it is annoying.
I use my own config but the gfx is r4ndom + the quad core comanglia stuff.
Shadow config is:
mat_shadowstate 1
r_shadowmaxrendered 32
r_shadowrendertotexture 1 //Actual shape shadows
r_shadows 1
r_shadowmaxrendered 24
Another pic where there are more shadows:
