--- Comment #18 from Tobias Jakobi liquid.acid@gmx.net 2008-02-25 13:19:59 --- Yep, that fixes the problem. Confirming this with Deus Ex. I'm going to do another test with Unreal Tournament and the corresponding renderer.
Going to write an additional mail to Jan so he also verifies it.
Thanks again Roderick!
