GPL: V2 SLI vs. Banshee...Banshee wins?

I've come across some rather strange results when running GPL. First off the system specs: Raven 16MB (3Dfx Voodoo Banshee) Now the frame rate results (sitting in the car at Monza): # of cars on track Voodoo2 12MB SLI (fps) 3Dfx Banshee (fps) 5 35-36 35-36 10 24-25 35-36 15 24-25 31-32 19 24-25 29-30 Additional: Lowest fps (19 cars, sitting at Monza while all cars drive away) 18.7 23 fps Hmmm...I thought the Voodoo2 SLI would blow away the Banshee but in my experience, it's the other way around. These -are- just numbers but gameplay is definitely smoother on the Banshee (as relected by the numbers). Is anyone seeing approx the same results that I am, either with the Voodoo2 SLI or the Banshee (or both)? -- Sergey Zakharov To reply, remove "-nospam" from my email address

The Obsidians come in to flavors, The S12 (single Voodoo2) 12 meg, and the X24 2 V2's with a total of 24 meg, which do you have?

Repost from original message: Raven 16MB (3Dfx Voodoo Banshee)" To clarify, "Voodoo2 12MB SLI" is 2 Voodoo2 12MB cards in SLI, in my case two Creative Labs 3D Blaster Voodoo2 cards. A Quantum3D Obsidian is *not* in the system. A Quantum 3D Raven (3Dfx Banshee) *is* in the system and handles 2D/3D. -- Sergey Zakharov To reply, remove "-nospam" from my email address

Banshees got a higher fill rate than Voodoo2 (read higher clock rate). Voodoo2 will surpass Banshee in games that use multi-texturing because of it's extra texture unit. (Voodoo2 can do it in 1 pass compared to banshees 2 passes) GPL doesn't use multitexturing so therefore...

On Tue, 27 Oct 1998 18:47:32 -0800, Sergey Zakharov Someone posted a little while ago, that when running in SLI mode, the clock rate actually lowers to about 80MHz instead of 90 or whatever the default is. So if you're running a game, which doesnt fully utilise the power of the SLI mode, then it will run slower. Heavily mulit-textured games like UNreal/Quake2 will tax the SLI rig a lot more than single texture games like GPL.

says... Wow I am getting better frame rate without sli too. On my 333 it went from 36fps 800x600 in a training lap to around 36fps without sli. This is not good. Now I have to figure out which games to turn sli off for. YUCK!!!!! Vamp
