No. I think thats an SDL/XOrg issue (see webpage).
I've added that to our readme. 

Xorg even seems to stomp a custom gamma setting..

If anyone else is able to correct the brightness on linux would you please give an example command line that works for you? Nothing posted has worked for me and I really do not want to try changing out the SDL lib systemwide. 

I just installed QuakeSpasm today, on my Mac mini 2010 (OS X 10.6.8), and tested it for a few hours. It's working very well, but I have a few comments about it and suggestions to improve the engine :

1. Currently, there is no FSAA (antialiasing) option. The GLQuake app (from Fruitz Of Dojo) has it and it's a great feature. Why not QuakeSpasm too ?

2. We can't put QuakeSpasm to the background, using command-H, like what we can do with GLQuake (FoD version) or Quake 3. This is highly desirable. Currently, we have to quit the app just to read our emails or to come here.

3. I noticed a frequent video glitch in QuakeSpasm, like a screen redraw jerkiness. I suspect this is because of the absence of any vertical synchro option. This is highly desirable too, since it's a bit painfull on the eyes.

And by the way : thanks a LOT to support that venerable good'old game. I believe that even by today's standards, Quake1 and Quake3 are still the best games around, even after all these years !

even on windows tabbing out of the engine produces generally bad behaviour from not having mouse control to the engine just crashing.

it's something that i think would be nice to have, if you get the chance.

Hmmm. That was not a known issue to me.

Barnak's suggetsions sound reasonable, and Ericw has sent a quick AA Patch but it has bugs. Oz is pretty cluey with AA, so maybe it'll appear soon. 

ok, so i go to check out what i was doing to create the problems... and nothing happens. :P
i think maybe that was in an earlier version and i got paranoid about tabbing out of the engine that i never noticed it got fixed.
thanks for that, then. :) 

I tested a new built of QuakeSpasm from Ericw with 4x FSAA, and your ne_ruins MOD is causing huge screen redraw problems. It's related to FSAA and I suspect it's also related to the large hi-res background picture used in your MOD (cloudy sky).

The same QuakeSpasm built with 4x FSAA is working great on all the other maps I tested yet. I didn't noticed any drop in frame rate yet.

I'll test the app on the Honey stuff later today... 

I re-tested the app with "sky" set to 0 (default Q1 style sky box) and the video problem is still the same (actually, it's a bit more persistant).

Again, it's clearly related to FSAA, but I didn't experienced the bug on any other map yet. 

take it up with the quakespasm team, i have no clue what's wrong!
stevenaaus mentioned that the aa thing has bugs. 

I am working on the (currently buggy) aa patch and sent Barnak the custom build. we're trying to debug it by email but i'm not totally sure what is wrong. 

Damm, that Darkplaces has a nice chase cam. HoT's works flawlessly, but view is obscured by a huge player model when your back is to wall. With darkplaces, the model just slides away, or maybe the camera is moved slightly forward of player ?. Proquake (1.30?) has a nice view, but go into start map , to the corner immediate left of normal skill teleport, and view is totally obscured. FitzPlus v2 gets obscured too, and a little hard to see differences, though i suppose they exist. 

I'm having problems with custom textures for the HUD (menus, console, etc). They aren't working yet, while textures replacements for the walls, floor, ceilings, items, etc, are all working.

For example, suppose you have a texture called "NUM_2.tga" to change some of the HUD elements, where do you put it in the id1 folder ? What is the directory structure for the HUD and console textures ?

Of course, I'm using QuakeSpasm... 

try /id1/gfx? 

Replacement textures for the maps. Nothing else. Not mdl models, charset, HUD, etc.

I don't believe this has changed in Quakespasm. 

quakespasm does do mdl replacement.
the textures go in /progs/ with the format: modelname.mdl_#framenum#.tga 

Glad to see they are using the DarkPlaces replacement texture naming convention. I'd like to see that as the "standard" naming convention because the other way of doing it is very kludgy.

(Engine wise, adding external texture support for sbar pics and menu items is a bit of a pain.) 

The menus and the weapons textures replacements don't work.

I've created a "progs" and a "gfx" folder inside the "id1" directory, and added the textures (from pk3 packages found on the Quake Retexturing Project web site). It doesn't show while in the game.

For example, there's a texture called "nail.mdl_0.tga" to change the nail gun. I also tried "nail.mdl_#0#.tga". Doesn't show in QuakeSpasm.

What am I doing wrong ? 

Typically. 

Are you sure about external model texture support? I'm not seeing that in the Quakespasm change log.

/Too lazy to actually check myself but eventually I will. 

oh my... i had rmqe in my gui loader and not qs.
sorry. :S 

Damn ! So no weapons and hud replacements in QuakeSpasm ?

O well, ... 

i still play with all the original textures and i like to disable texture filtering, so fitzquake and quakespasm are perfect for me.
but quakespasm isn't really an eye candy engine. i think you would be better served with another, fancier, one. 

Quakespasm is pure eye candy. and if it means that eye poop is not supported then yay! 

Should be picked up universally if you're going to support this at all. Other ways aren't just kludgy, they're flat-out broken. Check out progs/s_light.mdl and progs/s_light.spr in your ID1 pak0.pak - if you have progs/s_light.tga, which of these is the texture for? 

Then I'm wondering why textures replacement is supported for all the floors, walls, ceillings, etc, in QuakeSpasm, while the weapons and hud textures aren't.

This is weird !
