Half-Life 2

What works

Playing Game, High Quality models and textures, runs fine at full resolution(1366 x 764) great framerates

What does not

Full HDR makes game extremely choppy, slow the first 30 seconds of gameplay, mass physics and lighting effects can make game crash(just the game, nothing else) you can avoid this by not looking directly at whatever is happening for a long time(note that this is not much of an issue)

Additional Comments

Gameplay almost as smooth as win7, the game is quite addicting under wine. Ubuntu 9.10 RC 32-bit AMD Turion X2 2.0 GHz Integrated ATI Radeon HD 3100(running with fglrx and pixel shader on)

In case the game experience a huge slowdown to around 0.5 FPS, most probably you had hit so-called "some other (close) place displayed on the screen" bug. First time you may hit it is in the reactor room just before raiding down on a lift to the core chamber. There would a big screen displaying various parts of the reactor core room. This screen is the bug-trigger.

It was reported that the bug occurs only in case the "Offscreen Render Mode" is set to "backbuffer". To workaround the bug simply set ORM to "fbo" (or "pbuffer", if your GPU supports it) and the FPS will raise back to a playable values.

Keep in mind that setting ORM to anything other than "backbuffer" will break the game shaders dealing with refraction (water and alike) when the AA is on. Another unfortunate effect of setting ORM to "fbo" is that the performance level when using dxlevel 90/95 in Non-HDR mode will be very low, especially in areas where there are a lot of refracting surfaces. For now it seems that the best choice would be to turn off AA, set ORM to "fbo" and switch the game to the dxlevel 81 before entering the bug-triggering area. After successfully passing it redone the changes back to gain more FPS or better quality graphics.
