N3..opengl vs. direct3d w/ voodoo3

by rp » Thu, 07 Oct 1999 04:00:00

When using direct3d I seem to get a much better frame rate than with 3dfx.  Can
anyone confirm this?  I think 3dfx LOOKS better, but there is definite
slowdown..especially in areas with alot of skidmarks..
have pII-300
128 meg ram
voodoo3
Anyone else mess with settings?

Check whether Anti-Aliasing is set on when using Voodoo. It looks better but
I've found it can realy hurt your FPS. Try turning it off to see if the
frame rate improves. I seem to recall that it is turned on automatically
after selecting the Voodoo option at setup.

I have a Celeron 300a running at 450, V3000 card and SB Live soundcard.
My framerates are very close between d3d and glide. I agree glide looks
better because of the anti-aliasing, other than that I think d3d is very
close.

I just want to know why opengl is mentioned in the subject line?

I also agree with everyone who suggested you try with AA turned
off. I have a P2-450, 128MB, 12MB V2 card and the game is totally
smooth all the time. If you want a better framerate you might want to
upgrade the CPU.

You'll find some comparisions at:
http://www2.dicom.se/peter/compare1.jpg
http://www2.dicom.se/peter/compare2.jpg
http://www2.dicom.se/peter/comparesmall.jpg
(These were done on my Mac at work, hence the window styles etc.)
http://www2.dicom.se/peter/comparesmall.jpg is just a side-by-side
comparision of the car texture.

BUT... the story doesn't end there, because Antti Markus Peteri is
using a TNT2 and as you can see from _his_ screenshots, he gets much
better D3D texture quality then I do. Have a look at
http://www.tol.oulu.fi/~midpro/comparison.html
(The "your 3Dfx" he's refering to is my previous shot)

We never really compared settings/drivers etc. But I use a CreLab
TNT2u, Detonator 2.08, MipMap set at 0, method set to Bi-linear,
detail set to Best image quality, Anti-alias in h/w off. The only
thing I haven't tested yet is "Don't filter stretched bitmaps".
Hmmm...

Antii, you there?

well after messing with the frame rate (at bristol..driving for about 10
minutes each setting using alt-f to get the frame rate average) I get about 20
using 3dfx setting and 28fps using direct 3d.  the voodoo3000 is set at a
refresh of 85mhz and no other tweaks or settings enabled on the card.  maybe i
need to download the newest drivers.  I bought age of empires2 the other day
and it installed directX 6.1.  I seem to remember somewhere that after a
directx install that you should always reinstall your 3dfx drivers..it probably
won't change much, but for most apps the direct3d is slower.  I really can't
tell a huge graphical difference on the voodoo card b/w the 2 modes anyway.

1. N2002: OpenGL vs. Direct3D

2. N3: Voodoo2 vs Voodoo3?

3. GPL display issues with both OPenGL and Direct3D

4. N3 in Direct3D mode -- low frame rates

5. How do you adjust colors for Direct3D in N3?

6. which Voodoo3 card for N3 should i buy?

7. N3 and Voodoo3 3500 w/TV - Any help maximizing TV quality

8. N3, Cyrix 300, Voodoo3 2000?

9. n3 - voodoo3 question
