Half-Life 2

What works

Virtually all: installing from Steam, startup, gaming, comments, all dxlevels (70, 80, 81 and 90).

In order to get MSAA working there should be some changes done to the Wine registry and to the game configuration (additional info is in comments to this entry).­

What does not

• There are some minor render glitches when MSAA on ("gray straight line" like misjunctions on the big water surface when looking on it from the big height, e.t.c.).
• MSAA 6x mode don't work.
• HDR-Full mode works very slow.
• HDR-Bloom mode works somehow slow, some textures seems to be a little overbright.
• Without making some specific changes to the Wine registry shaders seems to be broken at some places (see comments in the next section).

Workarounds

What was not tested

Additional Comments

In order to enable MSAA you should set \\HKCU\Software\Wine\Direct3D\Multisampling to "enabled" and change \\HKCU\Software\Wine\Direct3D\OffscreenRenderingMode to "backbuffer". "UseGLSL" setting seems to give some FPS improvements when set to "disabled" (but it is likely to be GPU-dependent, as the speed increase when using GF6600 is much bigger than on GTS250 - but the absolute values on GTS250 are higher that on GF6600 in all cases). Without "backbuffer" setting it seems that some game shaders breaks (fancy cathedral windows, water refraction) when MSAA is on. Setting OffscreenRenderingMode to "backbuffer" fixes it. MSAA works only if set to 2x or 4x - it seems to be Wine-related limitation/bug. Coverage Sampling AA isn't working at all (when enabled using either "Enhance application settings" and "Override application settings" in nVIDIA Control Panel).
