--- Comment #34 from Anton Vorobyov phoenix@mail.ru 2012-07-20 15:38:35 CDT --- Another note - i have installed this game using how-to on appdb dota page, which seems to be partially outdated now. The things i tried so far:
1) Removing msvc 2010 redist (removed via uninstaller, removed overrides via winecfg) 2) Removing registry key HKEY_CURRENT_USER\Software\Wine\Direct3D\UseGLSL = disabled 3) In file drive_c/Program Files/Steam/steamapps/common/dota 2 beta/dota/cfg/video.txt i tried to set "setting.cpu_level" to 0 and 1
None of them helped to eliminate any lighting effect problems.
