view full story

http://ubuntuforums.org – i have a nvidia quadro fx1400 in the description from 3 sites it has benchmarks of directx:9c shader model:3.0 while downloading dungeon defenders from steam and following the directions from winehq on its dependencies, i start the game only to come up with a message saying my pixel shader is not 3.0 (yes i have turned shaders on in winecfg) i recall once getting it to maraculously work after changing nvidia drivers at least 2 weeks ago, but joining again after a game crash brought back the bad shader message and when i tried to recreate what i did last 2 weeks, it did not work so... what now (Hardware)
