Alien Arena is an open sourced game that combines a sci-fi atmosphere with the tournament style deathmatch of Q3A and UT2k4. Major graphical features such as GLSL per-pixel lighting, ragdoll physics, light blooms, real time lights and shadows, textured particles, shaders, and reflective water, create a colorful and immersive deathmatch atmosphere. The game also includes mutators, adjustable effects, bot skill settings, and fully configurable deathmatch, team deathmatch, CTF, All Out Assault, Team Core Assault, Cattle Prod, and Deathball games. The game features original artwork, with a dark, sinister atmosphere combined with an off-the-wall campiness, and trippy, techno type music. There are currently over 60 maps, loaded with weapons(each having an alternate firing mode) and powerups. Alien Arena has fast, smooth gameplay, & players can play online against one another or against the bots. Please post all support issues in the forums for the game.

Are you using linux or windows? If windows, just go into your arena folder and delete config.cfg, if Linux, then in your home directory, look for a .codered/arena folder, and do the same.

in C:/Alien Arena 7_33/arena you should have a file called config.cfg, delete that to reset the game's settings.

Check and see if it's somehow in the data1 folder. Otherwise, maybe you have explorer set such a way that it's hiding the file.

Then it should be running as default. What is the resolution of your desktop? If it's kicking out of full screen it's because your video card isn't liking 1024x768(the default setting).

You can also type gl_mode 1 in the console, followed by vid_restart to change it to the lowest resolution.

You should then be able to set it to fullscreen, and 1366x768 in the video settings menu.

hey devs one thing that im realy impressed is comptability (hard word)
ok my specs are (well more than other games)
-amd 1.9 dual core
-4gb ram
-1236mb own video ram (1500 shared)

so ?

i have vista and this game wont support vista ? or do it?
well i marked use comptibality (sumthing) mode xp
my max fps is 36 its very playable but when it drops to 6 i was OH GOD WTF and ping (in bot fight not online dedicated none and public no)
was 230 max O_o
but when i tried it without comptibility mode max fps stayed long at 36 and lags became little more rare but i got 50 of em in 10 min (small lag moments) so may you promise that you (dev team) build this comptibility with vista ? little more like i got fps 50 and lowest 20
(btw does this support multi cores ? if not i understand why i lag and fps is so low)

What video card are you using, and are you using the drivers from the manufacturer's website?

The game does support Vista. Did you try turning the settings down in the game's video menu?

thewonderboy Jan 2 2010, 5:05am says:

no i havent tried to put graphics low i though my pc can handle this easily
My video card is geforce 8800 gs (or i dont remember it could be 8600 gs) but update things.... I DONT HAVE ANY CLUE OMG
But i think bigest reason is this game dont have multi-core libbary/binary so it uses only my first core for game :/ am i right ?

thewonderboy Jan 2 2010, 8:13am says:

well i tried to lower graphics and one good vista trick (before and after lowering) only max fps increases and trick makes laging more rare if i put medium graphics i got max fps but its almost same if i take shadow shaders of and coupleof thing

Irritant_new Jan 2 2010, 10:29am replied:

Well judging by what you've said, first, you probably need to go to and download the latest drivers. Next, in your Nvidia control panel, be sure that "multithreaded optimization" is disabled, or application controlled. The game should play extremely well on that video card if things are properly set up.

ok i will try :) but i didnt get anwser that is there multi-core support as far as i know if i have 2 cores game cant use both if it dont have libbary/binary for it
It can cause my lags too
Ok heres situation

I cant play one of the most addictive game made because of mystery lag source :/

I can play it maybe 10 mins before big lag starts

I dont know how well you do know vista lag but main broblem in it is:
Pc have vista and wlan
Vista cant stop scaning wlan routers and keep scaning while it optimazes memory very bad= when it scans memory and prosec wide will disapear somewhere and it dont give memory enough to game when own processes are more important game losts touch and starts to increase ping but when vista stops scanning it will recover everything lag stops
To make this more lower simply shut down wireless connection but vista makes same command every time but now its not real so its smaler :/ i hope you notify this on readme or on homesite (if you are one from dev) i tell more when i got more info does it work :)

Irritant_new Jan 2 2010, 6:04pm replied:

When you say "big lag" starts after 10 minutes of play, are you talking about ping or framerates?

The game runs fine on dual/quad core systems, Vista, and Windows 7. If you're having problems, there is probably something else going on here, probably setting or driver related.

thewonderboy Jan 2 2010, 3:26pm says:

and if i have bigger specs lag is smaler or if i dont have wlan at all in my pc (or i have usb wlan adapter) vista wont **** up everything
So this is basicly laptop problem :/

thewonderboy Jan 4 2010, 8:11am says:

im talking about both ping and fps btw i tried that new warsow it had same lag problem but because it have lower specs it lags less but im still addicted to alien arena so
Are older alien arenas (stand alone versions) almost same ?
Im not active online player but i like bot games so are older still almost same (i dont care about graphics)
And i play older versions when i wait that i got idea how to fix this or if coming versions are more supported on vista xD

We support Vista fully now. The problem is you probably need to do those two things I mentioned before regarding the drivers and multithreaded optimzation settings.

alrite now i have updated
Last time when i checked there was not any new drivers but when i 2 day ago runed windows update there was new drivers
So im ready to check this again :D and i think that it may work because i have got problems with video card but one thing that is not positive
I runed medal of honor pasific assault and fps was originaly 32 averange and now it dropped to 24 :/
But i tell tommorrow my result

Ps rainbow six vegas 2 gameplay is smooth and stable so i think main problem is maybe videocard graphic... Way or something like if my videocard wont fuly support open gl games
Thats what i have noticed

I can play the game, but it gets "fuzzy" sometimes. The fps vary from around 50+ to 125 no matter what I set video at. However I should be able to run 4 times that speed. I run much faster than that in COD4.

Seems to me there must be some problems with quad cores. No matter what I adjust I can't seem to increase it.

I'm running intel q6600 dual/quad cpu with a PCIe 8800GTS 640MB vid card and 6Gb of OCz ddr3 1333 ram. I overclocked the cpu to 3.0GHz without increasing the fps. I have the 195.62 Nvidia display driver recommended by my card manufacturer and originally started with 151.something (I think).

I guess I'm just ****** I can't run it faster and can't figure it out. From what I've read there are others with this problem. Have you found any solutions for us?

Sorry to bother you, it seems you are busy enough but I haven't been able to find a more knowledgeble source.

Irritant_new Jan 20 2010, 10:20am replied:

Sounds like an affinity issue. In your Nvidia control panel, disable multithreaded optimization. If that doesn't work, you can try playing with the game's affinity cvars. sys_affinity can be set to 0, 1, or 2(by default it is 1). Note, you must close the game and restart it for affinity to take effect.

texasriffy Jan 20 2010, 8:18pm replied:

Thanks. I read your previous posts and tried all your suggestions. Affinity still at 0, however, a new development - I made the timing in the bios apic (or whatever that abrev is) instead of pet and now I run at a constant 60fps. No faster, no slower. My question now is: is that a good playing speed? Seems like its good enough I don't experience lag or feel that others have an advantage. My maxfps set to 125 cause I'm used to quake (1,2,3 &4) lol. I'm really getting curious as to why this setup won't run it faster aren't you? Anyway, thanks for all your work on this stuff. I'll keep playing and playing with the computer cause I like to do that. And reading your posts of course.

Irritant_new Jan 20 2010, 10:15pm replied:

That's a good playing speed, certainly, but your computer is capable of much more. In the game's video settings, try turning of vertical sync and see if your FPS then doesn't jump up quite a bit.
