Half dark/half light faces problem in Q4
Posted: Sat Dec 10, 2005 11:00 am
Ok here is the background:
I have Ati Radeon 9000 Pro WONDER graphic card (64MB).
Yeah, I know it is old but it served well with all FPS I played recently including Doom3. (Farcry, Boiling Point, HalfLife2 and several more)
Have 1GB of RAM and Athlon 2600XP.
I do see that Q4 hardware req. lists has no DirectX8 cards on it.
(which I didn't know before I bought the game)
Personally, I just think the real reason for that it is that developers didn't want to bother making it 100% compatible with it, although it should make game work fine, with some lower frame rate (it's doom3 engine after all). And it actually works fine exepct some problems I'll list here.
So I had several problems, two of which I solved.
100% dark shadows:
Solved by disabling them. Same worked with Doom3 that had same problem. Don't know other solutions. Not that it's needed, since switching shadows on halfs my framerate (plus looks ugly).
Completly watered down textures:
Solved by changing image_downSizeLimit and image_downSizeBumpLimit values to "512". Game for some reason set those to 128!, making textures completly blurry.
Everythin is green, like nightvision!
Solved by changing renderer to ARP.
Unfortunately this one introduced half light/half dark faces bug, and I don't know how to solve it.
Basicly one part of the face, body or somthing else is bright, while other is very dark. Similar anomalies happen to wall textures in some places when there is big difference in shading of two wall blocks.
I do remember having same problem in Doom3, but only when using High graphic settings, low and medium worked fine.
Any ideas?
P.S.
Anyway exept this, game works in managable frame rate (for SP).
15-30fps with 640x480 (medium textures).
And yes, I won't touch MP with this config.
