And what about fillrate test? with driver hack we got 200 mtx, and incredible result for the card! I'm, sure there is a second tmu, only disabled by driver...

Although the Velocity 100 sports a Voodoo3 chip, the board has got just one TMU enabled. About the score of 200 MTexels/s The TMU has only half of the job to do ! This could explain twice the expected score.

Well, it's obvious, at least for me : Avenger has got 2 TMUs, Banshee has got 1 TMU. If you tell the driver it's a Voodoo3, the driver will use by default 2 TMUs. Each TMU will render half screen area. The screen areas rendered by the 2nd TMU (TMU1) will remain black (unrendered), because Banshee has got only one TMU (TMU0). ...

I don't think it works this way. The 2nd TMU is for multitexturing and comes into play only when there are 2 textures to be rendered per pixel. And V3 does that in 1 pass. It's not that the 2 TMUs work together like an Tongue

SLI

or sth...

I believe this is correct from what I've seen in Glide64 (N64 Glide graphics plugin). The problems that the banshee has are mostly do to a lack of multitexturing. I think there maybe a way to do some sort of two pass gimick to possibly get arround that but it will most likely be slower. Of course, if one could make a driver that could do it that could be even better. A toggle in the driver to enable or disable would be nice but that alone would perhaps be difficult.

I'm sure there are tricks but at what cost.

mhhmm you 're right because not in all 3d games multitexturing is used...

p.s We must test driver hacked in single texturing game to see how they go Wink

Indeed, agrelaphon is right! the two TMUs doesn't mean SLI. Even the SLI doesn't render _HALF_ of the area. Instead, the scanlines are grouped into bandheights (strips). The first strip is owned by the first chip, the second -- by the second, the third by the first again etc. That means SLI (interleave). Ditto for four-chip boards.

Unfortunately, I haven't had the time to look over the driver again. Was busy with OpenGL and Glide Grin

Well, in a few days! I was busy with other things, but it must be done ASAP. (Glide is ready, I just need to learn how to do the file-release Grin

Hmmm... this is a bitch... Grin

Still needs a lot of work! As for the GL version, the trick is to implement as many extensions as I can (les connaisseurs know what I mean 8))
