Bio Hazard, what’s your video card, and what driver are you using?

Post by **Bio Hazard** » Mon Jun 26, 2006 2:09 am

I've got a GeForce FX 5700 LE 128MB DDR AGP8x at /dev/video0 running on nvidia-kernel-1.0.8762 ~x86 and nvidia-glx-1.0.8762 ~x86.

Everything else runs super-fast. It's just ZDoom that's slow. It's likely a CPU thing.

Did you try to launch it from an xterm? Something in the zdoom logs?

Post by **Bio Hazard** » Mon Jun 26, 2006 9:00 am

I've only launched it out of the console. Nothing looks out of the ordinary.

Did you try it without a WAD, in Doom2 for example?
Did you try my executable?

The only problem is I have no idea how to do this. I have the docs right here but I'm not sure about some of the things I need to do.

Then look at zdoom-2.1.1-0.src.rpm's specfile - it is precise instructions as can be.

What's ZD's Licence? Should I just put "Doom licence"? "ID Software Licence"? I know this isin't based off the GPL version.

BSD/DSC. If you find any GPL, you can keep it and stick it to your wall like a picture

The dependancies would be fmod, flac, nasm, and SDL?

A good packaging system should auto-find any dependencies.

Can you make a .tar.bz2 file for us Linuxers?

zdoom-2.1.1-src.tar.bz2 (download stats on SF show it's preferred over 7z)

Where would the installation part put it?

See specfile, /usr/games for binaries, /usr/share/PACKAGENAME for data. Also see Patch1 of the src.rpm.

Does the makefile automatically install it when I run "make install"?

It does not come with an install target.

Where do I tell the user to put the IWAD without editing the INI?

/usr/share/zdoom (after applying Patch1)

Does there need to be a ZDoom.ini file?

Doom will start with the defaults if there is none.

Strange, ZDoom is running excruciatingly slow. I can't run it at anything above 640x480 at 35 FPS. Are there any compiler hacks I could use to speed it up a bit?

Using OpenGL might help. (I also get only 83 fps in 320x200 mode using vid_fps when looking at a simple wall - this is a known X11 "problem". Under DirectX, I get somewhat over 799 fps.)

Bio, are you setting CFLAGS? I actually don't have any arch-specific settings set (no -march=yourarch).

If you have things setup right, this should give a good speed boost:

Code: Select all

$ export SDL_VIDEODRIVER=dga
$ ./zdoom

If that simply makes it crash, then tell me what you get when you run

Code: Select all

$ ls -l /dev/mem

and this:

Code: Select all

$ grep -n kmem /etc/group

As for your other questions:
The license for ZDoom is the conjunction of several licenses including the orginal Doom license and the license Ken Silverman released build under. The dependancies are flac, flac++, fmod, nasm, SDL, and zlib. The most simple summary of these licenses is: For noncommercial use only. Also, as I said before, there is no install target in the makefile. Lastly, distributing a zdoom.ini file is neither necessary nor useful.

I have 35 FPS with the console, but 60 without it. Yes, it’s a few.

Hello !

Does it possible to compile Zdoom without fmod ??

Thanks in advance !!

No, not at the moment.

Jim wrote:ESD and aRts (the funny capitalization is not a mistake, aRts is ) are crap for things that require low-latency and they are both no longer being developed. Use ALSA (or OSS failing that) for games and multimedia.

I would use ALSA if I could, but for some reason neither OSS or ALSA work correctly. Also on a different system, which was using ALSA correctly, I noticed that it would only play sounds from a single application at once.

Although I think my problem is with my onboard sound's driver

I don't know enough about Linux right now to know how to fix it. At some point I hope to upgrade from Ubuntu 5.10 to 6.06. I'm just waiting for an opportunity to get the ISO and write myself a CD. I don't feel like downloading another ISO with my 56k.

You can use ALSA with OSS emulation modules like snd-pcm-oss.
The multiple applications sound access may work with ALSA (it depends on your sound card, and works with mine), but it will not work if an OSS application makes sound.

It looks like ZDoom 2.1.4 is looking in ~/.zdoom automatically (as in, without cd'ing to the directory).

Hello to everybody!

This is my first post!

Today i'v made a working ebuild of ZDoom (version 2.1.4) for Gentoo Linux

This is a "work-in-progress", i'll submit it on Gentoo Bugzilla as soon as possible!

Some instruction (i'll insert them in ebuild):

Create an overlay and put the ebuild in games-fps/zdoom dir
put IWAD files in /usr/share/games/doom-data
run zdoom without parameters to choose IWAD from menù, or use -iwad <game>.wad switch

Feel free to test it!

:')
I'll do my best to iron out bugs!
Come Krillancello! We must join forces! Onward to portage victory!

On another note, I really need to clean out this thread. Most of it can go on the wiki.

EDIT: ZDoom isin't GPL-2. It's something like "Random mashup of licences V4.78.9.8.2.98.4"
I'd probably just stick with "DOOM" for the licence.
