..all you need is a *.grp file from shareware,full version,or full version atomic,plus the port binaries;).shareware is a 6 meg download:D.good old times.

oldskool, eh? it is amazing what those masters have realised with so few resources.

@dborca,

I tried forcing Doom 3 to use 16 bit colour depth in the 3dfx tools but I'm seeing no performance gains whatsoever, in most other games using/forcing 16 bit leads to a nice performance increase.

Any idea why this is not the case for Doom 3 ?, I'm not even positive that it is really forcing 16 bit in the game.

what driver are you using?

1) mesa wouldn't care less about 3dfxTool options
2) mesa does not allow 16bit modes when application requests 32bit mode (that's the sole reason Doom3 won't start on V2 with Mesa - yes, it was on purpose)
3) even in 16bit modes, mesa uses maximum quality for textures (that is, 32bit for Napalm cards)

this is the reason mesa seems much slower than 3dfx ogl (especially in 16bpp). maybe i'll change that, i dunno. or at least make an envvar so the user can choose.

@dborca,

Amigamerlin 3.1 R1 and MesaFX Doom 3 version of course

maybe i'll change that, i dunno. or at least make an envvar so the user can choose.

If you would please be so kind

i am usually not , but i'll make an exception for you

now letting alone the joke, i really can't remember why i haven't changed it already. perhaps i'm either using 16bit on 16bit cards and 32bit on 32bit cards (although 16bit on 32bit cards could be somewhat faster)

@dborca,



Thank's Daniel, your the best

i remember why it is the way it is right now. have you tried MESA_FX_IGNORE_TEXFMT?

[Voodoo5]

@dborca,

I enabled it, but I'm not sure what it does ?

The only thing I noticed was that the intro to doom 3 showed a higher fps (40 instead of 30),no change in game performance though and I'm positive it was'nt playing in 16 bit color.

heya dborca,

I posted a (fairly lengthy and detailed) query on falconfly.de about a couple of errors I was getting with Clusterball (one with pure Glide, and then one trying to use MesaFX to bypass it), and patience said to come here and ask you, as you're probably the best bet for insight   Could you possibly take a look and see if there's anything you know about?

I'm somewhat loathe to repost it because of its length, but I can do that if it'd make life easier.

Cheers!

i am not browsing FalconFly. at all! so you have to - either re-post the issue here or email it to me. in any case, limit yourself on your own postings (do not email me the entire forum).

Ah, okay - I'd seen you there before so I figured you visited there, too.

I'll e-mail a copy of the post (and only that post, promise to you later.

i got your email, i'll try to find some time for the bug.

Thanks, much appreciated!

ok, the problem was easy to spot, but hard to fix.

part of it was related to a problem in Mesa core (fixed now).
and part of it is related to the way this game uses palette textures. if i disable GL_EXT_paletted_texture, it will work (although the mouse lag is killing me). have to dig a bit more...
