Matthew Witheiler van AnandTech heeft een uitgebreid artikel gemaakt over de Hidden Surface Removal feature die door 3dfx in de nieuwe 1.04.01 drivers is geïntegreerd. Net als de eerdere bevindingen was hij erg enthousiast over de snelheidsverbeteringen die HSR teweeg kan brengen. Helaas zijn, vooral in de hogere resolties, erg veel fouten zichtbaar zoals wegvallende vloeren in Quake III. Het is dus duidelijk dat er nog veel werk nodig is om HSR op de bestaande Voodoo's speelbaar te maken. Volgens onderstaande conclusie was 800x600x32 met 2xFSAA en een HSR setting van 2 overigens wel speelbaar, waardoor je toch een snelheidswinst van 38% kan behalen:
The hidden surface removal feature of the 1.04.01 driver build is quite exciting. Not only does it show that 3dfx has some interesting technology in the works for upcoming driver releases and cards, it also shows the huge potential behind this technology. The problem is that there are still quite a few bugs that need ironing out.
The user most likely wanting to use the current form of HSR is one who owns a Voodoo5 5500 and plays with FSAA 2x enabled at lower resolutions. We have shown that at 800x600x32, an HSR setting of 2 results in a 38% performance gain without causing any noticeable image quality problems.
The other area in which the current form of HSR appeals is at low resolutions when paired with a Voodoo4 4500 card. Our tests showed no image quality problems at 640x480x32 with HSR settings up to the maximum of 4 and it is likely that more conservative settings paired with the 800x600x32 resolution will result in increased performance with little image sacrifice.
[...]The problem is the lack of acknowledgment on 3dfx's side. By not explaining what exactly is going on as well as proclaiming that future driver releases will not possess this feature, they may be shielding themselves from another company stealing their technology but they are also hurting their current product line. From now until the HSR feature of the Voodoo4 4500 and Voodoo5 5500 is finalized we must play a waiting game, waiting to see exactly what 3dfx can do with this exciting technology. From the looks of it, we may have some powerful technology on the way soon from 3dfx.
