Hello, I am having an issue with my Pentium 3 gaming box that despite my best efforts have been unable to fix.
In just about every game that has FMV I am getting framelag in the playback - it looks like the video is running at half the framerate - although there is no problem with the sound. I am also getting surprisingly 'stuttery' framerates in many games that my computer should easily be able to handle (Half-Life for instance). Splinter Cell seems to run at half the framerate that it should too no mater what settings I apply. Here's the really confusing part: when I disable my sound device through Device Manager, it fixes video-everything! (although at the cost of sound, obviously),
Here are my specifications:
CPU: P3-S 1.4ghz
RAM: 512 MB SDRAM
GPU: GeForce 4 Ti 4400
Motherboard: Aopen MX3S (i815e chipset)
Sound: Sound Blaster Live! 5.1 (SB0220) / (I also tried enabling an integrated SoundMax on the motherboard but it made no difference)
PCI: VIA USB 2.0
Operating system: Windows 98 SE
I have tried pretty much everything, removing the two PCI cards and enabling integrated sound instead of my Sound Blaster Live! 5.1, changing different Nvidia drivers in case that was the problem (the year 2002 driver seem to work better than the later ones though...), disabling/enabling other drivers. I even swapped in a different CPU (Coppermine 1.0ghz) to see whether that was the problem, and I also ran Memtest86+ for a few cycles.
I would really appreciate if somebody could help me, I just can't understand how enabling sound could give such an enormous performance penalty even to video playback, especially when I have a card that is supposed to process sound in hardware.
