--- Comment #39 from Petr B. bartos.petr@gmail.com 2010-02-27 01:48:41 --- Hi, althought it might be seen from various comments, it was not clearly said. I have upgraded from GF 7300GT to GF 8600GTS last year. On 7300 "UseGLSL=disabled" worked perfectly, on 8600 it is not. Therefore I guess there might be some problem with unified shader architecture on DX10 hardware, or different behaviour of nvidia binary drivers for those different architectures (upgrade was done using same version of drivers). Hope this post helps since RBR is one of my most favourite games...
