I'm running an AMD 64 3500+ with 1GB RAM and an nVidia 6600GT card w/128mb video RAM.
This is on an MSI board containing an nForce2 chipset and I am using the onboard AC'97 sound device.
I get around 90+/- FPS usually, but since patch V I have also been experiencing this sound glitch.
It's very annoying because, as someone else indicated, it causes the framerate to dive and I often come out of it hitting a wall.
Patch W hasn't helped and setting the sound delay up to 0.20 seems to have helped a little, but the problem still exists.
The devs changed something with the sound system on patch V and it has caused issues.
I think it merits further investigation.
Chrome, just save up and buy S2. The GTRs really are a blast to drift and they look damn good doing so.
Join the Kami^D Drift Server when you finally get S2 and I'll be glad to hook you up with some killer drift sets.
p.s. I bought S2 when I was unemployed. I have a wife, a mortgage, 2 car payments, 2 mobile phones and plenty of other expenses. If you want it bad enough, you'll get it.
