Game freezing in irregular intervalls - Page 3

Fast writes and SBA can actually be detrimental, and can cause freezes and lockups of the entire system, I don't remember the details if it only works reliably on some chipsets or what, but it should be explained in the gargantuan nvidia readme ( /usr/share/doc/NVIDIA*/README.txt ).

Specifically what I was curious about was if agp was shown as disabled, because that can cause choppiness and/or freezing.

Do you use the kernel's or nvidia's agp driver (agpgart and nvagp)? Check if there's an nvagp option under the appropriate device section in the X config, there are 3 values, prefer agpgart, prefer nvagp, prefer one but fall back on the other if it doesn't work, don't remember which value corresponds to which method, but it should also be in the readme; You could try using whichever one you're not using currently and see if you experience a difference.

mine is not an agp card. its an nvidia card on a PCI-E slot.

info on the card:
cat /proc/driver/nvidia/cards/0
Model: GeForce 6200 TurboCache(TM)
IRQ: 18
Video BIOS: 05.44.02.52.00
Card Type: PCI-E
DMA Size: 39 bits
DMA Mask: 0x7fffffffff
Bus Location: 05.00.0

since I do not have agp here, that would be displayed

here is the dir info for proc/driver/nvidia:
ls /proc/driver/nvidia/
<cards> registry version <warnings>

pci-e is out of my depth, I haven't bought a new computer in ages and thus have never personally messed with it; however a quick and dirty google tells me that agpgart is still involved even in pci-e stuff, and alternatively nvagp, can you cat the file called registry in that dir and show me the output?
