T&L?

[Nguyendot]

I recently installed the 1.07.00 3dfx drivers for my Voodoo 3 2000 PCI <yeah, i know, it sux>, and enabled the "Geometry Assist" function in the drivers. Now apparently I can use the D3D Hardware T&L functions in 3Dmark2000, and speeds in almost every game have increased significantly over the old drivers, and i can even run Mechwarrior 4 with full settings, which was impossible before because it simply did not have enough power.
So, i know the V3 chipset does not do T&L, so is this a trick, or something? Cause it did give performance advantages, and maybe the occlusion trick helped too?
Dunno, just wondering if anyone knew how this was possible that im running 50fps+ in Mech4 now on this crappy card =P

Didn't know they had the HSR and T&L drivers for the V3.....

What the T&L does is utilizes the SIMD instructions of your processor to increase the speed in which the operations run at. The occlusion it is a bit iffy how it works although it attempts to remove overdraw using some trick. It can result in severe image corruption, so much as to make certain games unplayable(although I've seen benches with a V5 pushing ~90FPS running 1600x1200 32bit in Quake3 using it, just wasn't rendered properly).

I'd like to see something similar to geometry assist added to Kyro drivers, might help allot with the lack of HW T&L.

Well hmm the last 3-4 releases of 3dfx drivers have had software T&L emulation this is nothing new

 

[Teasy]

Dark4ng3l, no'one said its a new feature, Nguyendot was merely asking exactly what the feature does.

P.S. you mean hardware T&L emulation

 

[Dark4ng3l]

Nope I meant it emulated T&L in software

 

[Teasy]

Well its hardly going to emulate HW T&L in hardware is it, if it did it wouldn't be emulating HW T&L is would be performance HW T&L

 

[Dark4ng3l]

Hmmm thats exacly what i said...

<< Hmmm thats exacly what i said... >>



Err no, I'm saying that there's no reason to mention the fact that its emulated in software as if it wasn't it wouldn't be emulating hardware T&L is would just be performing hardware T&L. The feature emulates hardware T&L therefore its "hardware T&L emulation". I was just being picky on terminology though so it doesn't really matter.
