incoming is known for its beautiful graphics, obviously needing quite a bit of CPU performance for generating it. However, Incoming does also not use multi-texturing, again no use of the second texture unit.
Again SLI Voodoo2 comes first of course and Banshee is on par with single Voodoo2. However, TNT looks pretty good in this one here, at least at 640x480. With a higher clock speed it could indeed surpass even SLI Voodoo2. Savage3D again at the 5th and last placing.
Incoming with Celeron 266 means CPU power is almost the only responsible part for the frame rate. The frame rates are almost all the same, the Savage3D having an edge to go last place again.
