Based on the extreme little amount of info you are giving us we can't help you.
Ohh, and this should be in a support forum.
There are also several useful threads stickied in the Tech Support forum (located <a href='http://www.unknownworlds.com/forums/index.php?act=SF&f=18' target='_blank'>here</a> )
I've got the exactly same fps levels as he. I've got a P4 2.0Ghz, 512 RAM and a GeForce3 ti200 so I think it's kind of low. In Quake 2 i get around 200 and sometimes even 300 if i turn vsync off, and in quake3 i get around 150.

The new particle system and dynamic lighting systems that came with 2.0 use alot of CPU.
Ehm, sorry but this is just plain wrong.
VSync locks your framerate to your monitor refresh rate, or in step of halfs of it(1/2, 1/4, 1/8, etc.). The reason for this is to give a smooth image with no tearing. It has nothing to do with computing/displaying performance.
(Edit: I carnt speel.)

Exceeding vsync will degrade performance. If your refresh rate is 60 hertz, then that's the speed at which FPS performance will be the best. <!--QuoteEnd--></td></tr></table><span class='postcolor'><!--QuoteEEnd-->

I think he means that if your framerate is exceeding your refresh rate you will only have worse performance, more frame tears and possibly also stuttering. This is indeed true.

That is a mere side-effect, vertical sync makes the graphics card wait when it has finished a new frame until the monitor has completed drawing the last frame before swapping the buffers.

This is wrong, it is 1/n (1 , 1/2 , 1/3, 1/4...). If it takes slightly less than 3 screen refreshes to complete 1 frame you will get a framerate of 1/3 your refresh rate since your graphics card will wait until the 3rd time your monitor is done drawing the last frame and then swap the image buffers.

It has a great deal to do with performance. Your performance can degrade if you exceed your refresh rate(stuttering, more frame tears etc., this is degradation in qualitative performance), your graphics card will be rendering more than nescessary(since it can't all be displayed) and your CPU will use more cycles to keep up without any gains. If you are using other programs in the background, such as running an undedicated server on a LAN you might not want to waste CPU power.
If vertical sync is on and you cannot keep up with your refresh rate you will end up at the nearest 1/n framerate to which your graphics card can keep up, this may mean ending up at 50 fps when your graphics card could only draw 95 fps, turning off vertical sync will allow you to have 95 fps instead which is obviously better performance quantitatively but not qualitatively(I would prefer the smooth, tear free 50 fps).
What a long post to say that i was wrong about the

The rest of it is basically agreeing with me or rewording what I said <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
So... You agree that uranium is right then? <!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' style='vertical-align:middle' alt='confused.gif'><!--endemo-->
It might be your agp driver(it depends on your mb). It could be old graphics drivers. Tell us what kind of card you have and that might help...
Well after trying that one guys suggestion to turn off high detail particles and dynamic lights, it's still doing the same thing so I'm stumped.
It doesent sound logical to some.. but v sync HAS to maintain 60 fps... as SOON as i cant.. it drops to 30... then 15...
I turn mine off and i get 99 fps... but if its on... i get 15-60....

Now i only get for 75 norm for some odd reason ( hey hey thats a happy 75 but still what happened to my 100)
I've looked everywhere and tried everything but cant seem to get my fps to go over 50 or so, and usually they hang around 35. Doesnt matter if I have 800x600 with lowest detail or 1600x1200 with 6xFSAA and 16xanisotropic filtering.
I wouldn't think that the blame would be bad drivers, considering that I installed the same drivers off of the same disc in the before and after situation. The really sad part is, I get lot better fps in D3D mode than in OpenGL, but my crosshair sprites dont appear correctly so I cant use it.

vertical sync will allow framerates as high as your refresh rate, you are getting a refresh rate of 60 Hz, this is a known bug of windows XP/2000 that can be circumvented. If you turn off vertical sync you are merely hiding the problem, not solving it, you can still not get a framerate higher than 60 Hz under any circumstance if your refresh rate is 60 Hz, this means equivalent to 40 frames are dropped, simply not shown, each second.
You should force windows XP to use a better refresh rate and stop defaulting to 60 Hz in openGL, even if you are going to have vsync turned off. 60 Hz flickers badly(as much as a television set), to avoid eyestrain try 75-100 Hz if your monitor can do it at the desired resolution.
they finally have a solution to solve the 60 hertz refresh rate in their driver..
go to "refresh rate override" and change ur "default" to the max refresh rate ur monitor can take
if u choose over the rate ur monitor, it will become momentarily black
btw, can i overclock my motherboard agp to 8x agp ?? i have a 4x agp mb but i got a 8x agp card(fx 5600). although i getting 99fps almost all the time except in huge turret farming and fighting, i do play other game such as battlefield. and i wan more fps! so how?
Just a side note:
TruForm basically "smooths" out polygons on models, effectively TRIPPLING OR MORE the amount of polygons shown and making them look super-duper smooth. Turning off TruForm will CERTAINLY help out your frame rate as it reduces the amount of polygons and calculations needed to do so, however, the models wont be super-duper smooth.
Example:
"OMG I R HAEV TEH AMD 2800 @ 2.08 GHZ!"
"OMG U SUK I HAV TEH PENTIUM 9822 @ 2.8 GHZ!"
Except the AMD vastly outperforms the pentium... Pentium markets to the kiddies who don't know jack and think MHz is the only way of measuring a chip performance...
a p4 1.0ghz can win a p4 1.5ghz processor IF they have a good hard drive, good ram(i suggest rd ram for pentium), graphic card, monitor and all the accessories
huh hur. pentium is getting cheaper and amd getting expensive day by day <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif'><!--endemo-->
u are for amd, i am for pentium
this is not "amd better!! or pentium better!! " thread
that dude ask how to get his fps back, so let get back to thread ok?
2. Some people can experience motion sickness and/or an onset of seizures from only a few moments of low framerate.
3. During play, framerate dips down. If you actually improve fps, and not just remove limits, it can really help during a tense firefight.
4. A higher framerate allows you to better deal with a higher mouse sensitivity.
5. I think it helps you to bunnyhop more effectively...
Besides that, I can't think of anything.
Edit: Of course you will play worse below 20 fps. He was referring to framerates above 65.
