View Full Version : Forcing render path...

10-19-04, 11:55 AM
Is it possible to force a different render path rather than the optimal selected for a specific card under Doom3 ? IE running the NV2x path on a GeForceFX rather than the ARB2 ?

i'd check the console commands. im pretty sure you can do it.

I didn't find anything useful on the net. Most sites only list those console commands needed to cheat or to tweak the most common options

The console command is:

r_renderer XXX

Where XXX is BEST, ARB, ARB2, NV20, etc.

Wow ! Thanks :)

OK, I've made a few tests just to discover... that forcing the NV10/20 path or even the standard ARB path on my FX5700U cause massive rendering errors. I swithced to an old GeForce3 and it can runs flawlessy its default path (NV20) as well as NV10/ARB.

After doing some tests and comparing image and shadow quality, I strongly believe the game looks much better in arb2. The blood and textures have more color and depth and the shadows don't appear as black. Give it a shot and leave some impressions...

arb2 is the high possible IQ path in the game and looks a whole lot better than any of the others.

I still wasn't able to run w/o glitches any other rendering path on my FX5700

I did some tests with the GeForce 3, though. I noticed some banding when using the GeForce 3. The ARB path seems to lack of specular but it's abit faster than the NV10 path with specular disabled. The NV10 path is too slow to be used with shadows and sepcular enabled

Possibly in the future I will do some more tests

ARB2 & CG are the best quality ones. "Best" leaves the textures blurred a bit and some of the shadows have no depth. I'd recommend people who have the horsepower to try out ARB2 or CG.

Ok, I resolved all of my problems which seemed mostly driver related.

I took the opportunity to test Doom 3 with 3 cards I have ATM: my usual 5700U, a spare FX5200 I had around and a recently purchased GF4Ti.

I've seen interesting results. They gave my a deeper insight of the NV3x architecture. Today, or tomorrow, I'll post some cross-parth comparisons in the benchmark forum

I'm not 100% sure, but Cg and arb2 are exactly the same.
