The patch works perfectly for me against 1.1.24. Flashlight works as intended
in multiplayer campaign. I would like to see this get implemented as the FPS
increases are great. I no longer have to disable HDR in Left 4 Dead, albeit
settings must still be on low for models, textures, etc. and the resolution
doesn't go past  960x600. I know that sounds preachy and stuff but this patch
is a step in the right direction.

Patch working extremely well here on 1.1.24. I got over double FPS (70-80) most
of the time!

I can in fact raise the eyecandy with this patch to respectable levels (medium
shaders, models/text. high, effects high) ALTHOUGH regular shadows are broken
for characters, zombies, and etc. Other than that its a HUGE performance boost.

Huh, another update, funnily enough I get this corruption now against 1.1.26.
Although this coupled with using ARB makes L4D run smooth enough. Since I am
unable to downgrade from 1.1.26 to 1.1.24 (the wine folder gets "corrupted"
when updated to 1.1.26 and steam crashes on launch when you revert back) I
would wish that this error gets worked out.
