Default Random Choppy Frame Rate

I'm using a Leadtek GeForce 6600GT (AGP) with Leadtek-branded drivers
(v67.23). For the most part games run OK, however the racing game, Midnight
Club 2, suffers from occasional choppiness. Normally the frame rate is very
fluid, but sometimes it gets very choppy, even thought the same race may
have run smoothly in a previous instance. I'm hesitent to upgrade the
drivers since I don't want to lose compatibility with the rest of my games.
Does this sound like a symptom of older drivers or should I look for the
problem elsewhere? I already scanned for viruses and spyware but found
nothing. TIA


System Specs

WinXP Pro, SP2
Intel 865PERL motherboard
2.4 GHz P4 (800MHz FSB)
1 GB dual channel DDR SDRAM
GeForce 6600GT (AGP)
160 GB WD SATA HD

What size is AGP aperture set to in BIOS? Try increasing it to something
like 256 MB.

Well why not try the latest NVidia's official 78.01? Those drivers seem
to be "old as a stone".

See if the HDD led is flashing when the choppiness occurs. If it is,
it's due to the system paging out to the swapfile. Sometimes a heavily
fragmented HDD can produce this.

Thanks for your reply. Up until now, the only surefire fix has been
enabling Hyper-Threading on my P4, but then some older games won't run. I
suspect that the pausing is related to background processes competing for
CPU time, but tweaking the AGP aperture couldn't hurt. It's currently set
for 64 MB.

Game compatibility, some of the games I have are eight years old but none of
them crash with my current drivers. Besides, I thought newer drivers were
meant to fix problems with newer games (sometimes at the expense of older
ones). What's strange is that the same MC2 race can run many times in a row
then suddenly get choppy the next time. That's why I doubted it was a
driver issue.

try adding another stick of ram if you can afford it or try different
settings or send it back.
