Another small question: does anyone know of a hacked version of glide2x.ovl that works with this emulation but doesn't have the unskippable 3dfx logo at the start? It's sort of annoying..

Environment variable will do it.

FX_GLIDE_NO_SPLASH=1

A good source for other environment variable. They have information on other things as well 😀

Thank you!

Another question: this patch only emulates a voodoo 1 right? I tried a v2 glide2x.ovl in tomb raider and it ran, but with degraded image quality. Though that's maybe tombraider not working well with that ovl.

(since this is using grep, it's missing env variables that do not start with SST)

Re: Voodoo Environment Variables

quite useful. The GAMMA env variables seem to do nothing in tomb raider, is this a patch bug?

Tried archimedean dynasty now. It seems to have z-fighting problems if you enable the cockpit. I was also wondering if there is a big difference on this game. It seems to me the view distance is still somewhat equal? That can't be right.

There's a thread about compilig DOSBox with 3Dfx under Linux: Tutorial: dosbox with Glide under Linux

I tried patching the source with the patch supplied, but it says "Reversed (or previously applied) patch detected!" and doesn't apply to it anymore

Which source? The code from SVN or th code from ECE?

the one from ECE (not sure how this ended up here, and not in the right thread)

Hi Yesterplay80, I also would like to build your ECE release for linux.
However in order to apply your 1_voodoo_gl.dif patch for linux, we first need to revert the one you've already applied (which only compiles on Windows).
So is it possible you could post your current vooodoo patch, so we can revert that one first?

These are all the patches and changed graphics I used for the Linux version of ECE:

I'd recommend using these instead of reversing the patches of the Windows source code.
So there was some need for a linux version after all it seems...

Thanx for the patches, will try and apply and compile over the weekend. And yes there is always a need for a linux version

I was using a big-faffy version of Glide support so I've just switched to your patch to see how well it works in comparison. Does anything need to be specified / enabled or turned on anywhere to be able to use it? Or should it "just work"?

It's not "my" patch, it was made by kekko. I just adapted it a little bit. It should just work, because it wraps Glide calls to OpenGL, so nothing more is required.

Yes, there is, thank you.

Yesterplay80 wrote:

could you supply the build again? I tried and gave up merging the patches/compiling

here is a 32bit build with only the voodoo patch applied.

here again, a Linux x86 32bit build with voodoo patch applied (only the voodoo patch).
It is working with Tomb Raider 1 and Archimedian Dynasty.
But Screamer Rally is crashing.
Maybe someone could help debugging?

Screamer Rally segfaults when using 'output=opengl' or 'output=opengnb'.
It works with 'output=surface' or 'output=overlay' in config file but it is unplayable slow.

Funny that dosbox-daum from 25.jan.2015 was working perfect. But this I do not get compiled.

Hi.
What's the principle obstacle to get 3dfx/opengl scaling (fullscreen) work?
Would like to play AD but without it switching to fullscreen the Voodoo emulation seems to be pretty useless... Or does it work for you (on Linux)?

BTW the source from the ECE website compiles on Linux (latest r4078 as of now) albeit with a couple of hiccups (mostly a few windoze-only bits scattered here and there and a missing typedef, easily fixable). Speed is good in AD, GALLIUM_HUD=fps shows anywhere between 20 and 45-50 fps on the MOGHS instant action map, depending on the scene in view. Keep in mind tho, my CPU is a pretty old FX-6100 @4400MHz
Whereas DOSBOX-X is dog slow and has a lot of rendering artifacts (mostly HUD and cockpit) and also won't go into fullscreen...

CARMA works in fullscreen w/Voodoo emu. Performance however is pretty dire (regardless of windowed/fullscreen).

Is the problem game-specific then?
