X1650 gives low performance

Hello,i have ati x1650 pro ddr2 with 256mb of ram for AGP and it gives me lag and low performance in games....I have ati 8.33 drivers ,cant install new cause GFX wont accept it.
every game lags (old postal 2 for example ),not to talk about never games like infernal ,wolfenstein 2009,call of juarez (first part),jade empire and many popular games that demand SM
3.0 and single core cpu...Even on everything on low .resolution lowest possible everything lags
Rest of specs
mobo4pe2-x
ram:1,5gb ddr1 400mhz
proc:intel celeron 2,4ghz
hdd:wd 1600aajb 160gb ata
psu:chieftec 550W ABA
Card is plug to the additional 4pin connector and inserted properly to mobo
Fan is 'dust free' so its now overheating (although i cannot check temperatures cause card hasn't sensor for it ....

Can you help me somehow to resolve this problem
tnx

The reason for the lag is that

1. You have a single core CPU.

2. That GPU wasn't the fastest when it was made, nevemind years later.

it is true its very old but i watched videos on you tube and talked to folks who made them(they have the same card and single core even less ram then me ) and they can play these games better then I with normal fps around 20 and lag free
so I am thinking its some issue with card or some settings in CCC
Also some older games i used to play with ati 9250 have lower fps with x1650 pro (cs 1.6,Postal 2,WoW)
And how can i check my GFX for some damage or malfunction ????

here's the gpu-z readings

is it normal ???

I'm doing just fine with Crysis at 20fps.

And memory speed (like 1333vs 1600) isn't a major factor when gaming, GPU/CPU is more likely the bottleneck.

The human eye stops addressing frames past 24.

(The small benefit is reducing distance by frame, but hat's very minor)

All Movies, Tv, everything runs at 24fps.

I don't knwo, I own pretty hard at Crysis at 18-25fps lol.

You might want (but you don't need) 60 frames, but there is no way in hell you can see the difference between 50 and 60 frames.

No matter what you say.

No way ANYONE can tell the diffrence bewteen 50 frames and 60 frames.

Maybe something mental, who knows. You think what you see is better, so you convince yourself you can see a difference.

And also, We did "Eye testing" at my High School, and I scored in the top "1%"

The human eye is not a camera.

We stop perceiving something as flickering anywhere from 40-60hz (depends on person to person, and the application). Though flicker is a different beast from the frame rate. The jerkiness we see and complain about is due to the difference between frames. Motion will often look jerky if the frame rate is not high enough to minimize the difference between frames. What you want is the target to blur for it to look normal and not jump, some people are much more sensitive to this than others, and will even get sick watching a low frame rate movie/game.

Generally frame rate stops looking jerky at about 30fps for anything but fast motion, at which point you get obvious strobing (the same effect that makes tires look like they spin backwards on TV) which is a real pain in the ass in an FPS. When the flickering goes away we just perceive it as a dimming of intensity instead of as bright and low points. Mind you, LCDs can't flicker as the light is always on in one way or another, this is an issue for CRT and theatre displays.

With an action packed scene in an FPS it is perfectly reasonable for a human to notice the strobing at up to 60fps. Flickering is caused by our persistence of vision, which is also what allows us to notice motion looking a tad 'silly' in a frame by frame representation of the motion.
