In-game stuttering (Nvidia)

[avp2501]

I've been playing KF since release with no issues performance wise (Pre-may 2009 Nvidia Drivers) but yesterday I updated to the newest Nvidia drivers (Oct 191.07) and every here and there I get the odd stutter like there's this split second drop in FPS or something.

Any ideas about this?

My Specs:
OS: Vista 64
GFX Card: nvidia 9600GT

You might have simply not noticed this before. There has always been a slight glitch every time you see a new Zed on a map when that map hasn't specified each of them in one of the Zombie Spawn Volumes. This will be fixed in the next update, but that's my best guess as to what you're now noticing.

I've got stuttering too since updating my video drivers in august (no issues before). The various KF updates and following drivers updates didn't fix it.
The stutter only appear in DX9 mode so using DX8 allow me to play but I miss antialiasing .

I heard this issue already existed in UT 2003/2004 and no solution were available other than changing the render mode. Please tell me you or Nvidia can do something about it.

Specs:
Window vista 32
Geforce 8600 GS

Generally, if an issue exists in UT2K4 and was never fixed, we probably won't be able to fix it either. We certainly try and in some cases succeed, but usually, if the developers of the engine don't fix it, it'll be very difficult for us to fix it. We'll look into it and see what we can figure out.

Try defragmenting your paging file.

Since release I've played KF on max settings and it's run Super Smooth with not even the slightest sign of a pause or stutter until I installed the latest nVidia drivers.

The game is now sometimes unplayable. Look zombie in the distance - stutter - Dead

So today I thought i'd have a play around with the display settings since someone had mentioned they only get this in directx 9 mode.

If I turn off Anti-aliasing then the game runs perfect. Turn it back on and Major Stuttoring.

I find this really odd since I had no issues with it before updating the drivers. I would revert back but the old drivers don't make use of PhysX.

Your answer is quite simple then. Roll back your video card driver.

CUDA has been available for Geforce 8 series and above for over a year. Surely sometime between then and now there have been at least one if not several driver versions.

-edit: though probably not for Vista...

yeah there probably has been however if theres nothing wrong with my machine I don't tend to go looking for the latest drivers.
