I did a quick benchmark using CART Precision Racing (full version) to
find the performance difference between the 3Dfx (Orchid R3D) and the
Riva 128 (Viper V330). I drove while my brother watched and recorded the
high/low framerates. The test was configured as follows: All graphics
options "on" or "full", sound was set to 16-bit stereo, track used was
Michigan in practice mode with no opponents. Measurements were taken
during one full lap (-after- completing one full pre-lap to load in all
textures). The R3D was tweeked using the following in win.ini:

[3dfx]
SST_GRXCLK=54
SST_VIDEO_24BPP=1
SST_SCREENREFRESH=75
SST_GAMMA=1.0
SST_FASTMEM=1
SST_FASTPCIRD=1
SST_MEMINFO=1
SST_MEMINFO_LFB=1
SST_MEMINFO_TEX=1
SST_SWAP_EN_WAIT_ON_VSYNC=0

 Brief system configuration:
P233MMX (o/c to 250Mhz (83.3Mhz bus))
Asus T2P4 rev 3.2(512k)
128Mb EDO
Viper drivers 4.10.01.0015
3Dfx D3D reference drivers 2.13

         Framerate(lowest) Framerate(highest)    
3Dfx                 14                27
Riva 128-            13                22

The results show that the 3Dfx is a bit faster, at least in -this- game
and using this particular benchmark. I know that the Riva beats out the
3Dfx in other D3D benchmarks...maybe the other benchmarks don't strain
the chipsets as much as CART does. Regardless, this wasn't a test to see
who beats who. It was just a test to see which card I should be running
when playing this rather "demanding" game. I like, and use -both- the
Viper V330 and the R3D...I play Jedi Knight in 800x600 on the Viper V330
and am -very- pleased with it's performance.

To reply, replace "nospam" with my organization.

You didn't mention whether or not the Riva was the AGP version or the PCI
version.  The AGP Riva I have absolutely smokes...

Presently, the STB Velocity is the best video card that you can buy,
assuming that you are searching for a good all-around SimRacing video card.
Gp2 will run great. N2 and Icr2 will run great but you will not race the
rendition version.  Soda will be a blast, very fast (remember SODA is
presently the best pure simracing title on the market).  With F1RS you will
have the best D3D results of all the D3D cards.  C:PR is maybe the only
flaw, but it is because of some incompatibility between the game and the
card.

You can argue me, I know some people here that can be on my side (Randy and
other simracers here).  But I have a Dell P2 266mhz, so the results may be
different on less powerfull systems.
