--- Comment #10 from Marek Olšák maraeo@gmail.com 2011-06-08 16:13:30 PDT --- The log clearly says HL2 uses loops, which r3xx-r4xx can't do. All the r300 error messages seem to be unfixable hardware limitations.
Is there a way to disable the shader model 3.0 in Wine/DX9? The shader model 2.0, which the hardware was designed for, doesn't have loops, and HL2 must support that (otherwise it wouldn't work on Windows either).
