Hi,
I just downloaded this game and I noticed A LOT O LAG on this game not only on multiplayer but campaigns too.

This is very few information you provide.

Please submit more information.
PC:
CPU, RAM, GPU, OS, and so on.

Additionally you can activate the FPS counter ingame. You find it in the "EFFECTS" section of the options menu.

I personally suggest you set the effects too high.

Guess what? That's not lag.
Lower the graphic settings.

I Tried everything but when I get in to like big gun fights it starts to slow down and lag.? O and my memory is 128mb, and I have GeForce FX 5200.

Well thats indeed not the best suited hardware for a fast 3d game especialy more memory would be good.
What you can try is to start Nexuiz, open the in-game console by pressing shift-escape and entering: exec low.cfg;vid_restart that should disable most effects, turn memory usage down and hopefully make your situation better. The default settings of Nexuiz are for sure too much for your hardware. Though i'm not sure how much it will help..
You can display the FPS (frames per second) by entering showfps 1 in the console. Values below 40 are bad for general playing.
Could you do (again in the console) tdem demo1 and report the min/avg/max fps that are displayed after the demo has played?

yea you know what i just deleted it. Its not worth the trouble no offense. good game and all though. BTW my fps min was 5 and max was 14

Strange, even on my Geforce 2 MX it performs better at lowest settings. But this might be due to this old thing not supporting anything of these advanced features.

Well, even Win XP doesnt run too well with only 128 MB, and no matter how mighty Your VGA or CPU are, 256MB of RAM is the least You need to have built in.

Oops, I missed that. I'd say the minimum is 512MB RAM. Using CheapAlert's TinyNexuiz, 256MB or maybe 192MB should be possible. 128MB? Forget it.

Bad news I now bought a whole lot of memory that i now have 1 gb on my computer yet it still has a min of like 6 now and a max of 17 fps but, yet still laggy.

I guess you already updated your nVidia drivers?

Some more info would be needed to say anything here.

Main things thats good to know:
Operativ system, CPU, Chipset, GPU, Memory (type, not just size), Driver versions.

Does other OpenGL Games work well?
Do you run a multiscreen setup?
