DXTC in v3´s

[Fantasma]

The files 3dfx16vs.drv and 3dfx32vs.dll in the version 4.13.01.0028 which are in mikepedo´s 1.1 driver and x3dfx 1.07.00 drivers supports the dx texture compresion although it results in white textures. Why don´t develop this?

[koolsmoky]

That's becuase the Voodoo3 hardware doesn't support native DXTn formats. Even if the drivers are able to convert DXTn to other compressed formats that the V3 can handle, it would only be useful for games that pre-load all compressed textures because doing so during game play would be too slow.

Yes, but you gain compatibility with lots of games and it´s an advance
Also, now I think the most important thing is the compatibility but it´s only an opinion

Yep! and

Well, what's the sense of compatability if it will result in 1 frame per 3 seconds? Some things are best left alone, and I think this is one of them. Drivers aren't developed to allow compatability when it will result in a completely useless gaming experience, at least that's my opinion. Sorry mate, but I think the team's time is best spent elsewhere.

Of course a Voodoo3 user doesn't think probably the same and this is normal that this user hopes something, no ?

While amp_man has a point, I shall favor Nightbird on this. Back in those days when I had a Voodoo3 only, I would have thought the same. Unfortunately, our team is very small (me & big K) and time is a limiting factor. Perhaps a bit of SW rescaling won't hurt anyone. That is, on condition that the "patch" won't slowdown the driver.

I have always my Voodoo 3

Yes, it´s what I mean:D

Is it then possible to disable texture compression in 4.13.01.0028 core? There are still enough "goodies" in those driver releases but the white textures are a big pain in the ass. Is there a reg. key to be add or changed to disable DXTn?

[ps47]

if you have white textures with a voodoo3,that means the textures are either too large,or compressed (this is caused by the game,not by the driver core-texture compression and other VSA-100 features are automatically disabled for voodoo3).voodoo3 cant display such textures,so it will result in some textures being white.the texture resolution problem can be fixed by running under opengl and using mesafx sw rescaling,but that is not always possible.sw rescaling under D3D should be possible,but I'm not sure if SFFT wants to do it.the problem with texture compression can be fixed as well,but this requires a patch for the problematic game (such as the doom3 voodoo2 patch,or the not released call of duty voodoo2 patch) that will convert the compressed textures to some format the voodoo3 can handle..

So if it is not a driver's core issue, why when I run 3DMark 2001 SE build 330 on my system (Duron 1100@1200Mhz, 256Mb DDR, KT 266A MB and, of course, Voodoo 3 3500TV PAL) with Amigamerlin 2.9 driver (core 4.12.01.0666) all the textures are displayed in corect colour (by the way, I get 2020 3DMarks - is that a good score?) and I get no info about texture compression in the "Display and CPU Settings" section, but when I install Mikepedo 1.1 driver (core 4.13.01.0028) on the same system and I run the same 3DMark 2001 SE buid 330 allmoust all textures are displayed white only and in the "Display and CPU Settings" section clearely states "texture compression" (and runnig the benchmarck I get less than 1700 3DMarks!) I concluded that the 4.13.01.0028 core (Mikepedo 1.1 and other drivers) enables by default the texture compression, allthough it is a feature not supported by the Avenger chip of the Voodoo 3. Because the 4.12.01.0666 core (Amigamerlin 2.9 and others) is also usable both for Voodoo 3 and Voodoo 4/5 and yet does not enables the unsupported texture compression when in use with Voodoo 3, it must be a way to do the same thing with the drivers based on the new core (maybe a registry key?).
Please, there are many guys here that are driver writers, please give me an answer

[ps47]

well..it may be a bug in 3dmark,maybe the beta core is not identified properly.3dmark behaviour is not important,its just a tool for benchmarking,not a game.I had no problems with white textures when using SFFT driver on my voodoo3.but I will load 3dmark and see myself..

[ps47]

ok,ran 3dmark 2001se on both amigasport and SFFT for voodoo3,and indeed,there are (very) few white textures in the car chase (high),but the rest of the tests went fine (1965 points,wooo).so I would say if you have BIG problems with the white textures,its a bug in the mikepedo driver..

[SuperFurryFurryThing]

It sounds like the Mikepedo core thinks that your V3 is a V4 or five and so is reporting DXTn texture format caps, are you sure that this core isn't V4/5 only.
