Since I had no real hopes for a quick solution from Hasbro I started testing
GP3 with my Voodoo2 SLI. The performance is still the same as the Software
mode but the image is better. My CPU usage is under all conditions (dry and
rain) at 100% or below, exept for the start at 120-150%. I use a Celeron 500
and 196MB to back the two V2's. The settings are not "GeForce2 DDR
64&PentiumIII_1.13GHz" style but here they are:
Control panel:
- Don't sync swaps
- Force trilinear filtering
- Enable anti-aliasing
- SLI enabled
GP3 Video option:
- 800x600
- Display textures: All on
- Plot in mirrors: Track (adding textured smoke does not give a big CPU hit,
few % in dry conditions)
- Reduced texture detail: On
- Cockpit view angle 130%, both more realistic and CPU power reducing.
- Track side objects Medium.
- Framerate 18.2, must be same or lower as recomended. Going higher gives
bad (high) CPU usage and sometimes chocking at 350+% CPU usage. Try starting
with a low number and increase until GP3 runs (quick race, dry and rain)
smooth.
cards.txt in the [Voodoo2 3D Accelerator] section:
- slivoodoo=1 [ 1 if you have SLI, otherwise 0 ]
- reflections=0 [ big CPU impact in rain conditions when 1 ]
Don't bother about bilinear=1 since we forced trilinear filtering.
Hope this helps some of you.
