Ever since the last beta patch (95417) I've been having my FPS suddenly drop then shoot back up to what it was running at, causing a short stutter/lag/freeze/etc. I had no issues before the patch and it doesn't seem to be a hardware or overheating issue. It's a very annoying problem and also frustrating since I can't pinpoint what is causing it. At this point I have to assume it's the beta patch, but can't be certain since I can't seem to really find anyone else having the problem outside of the 2 or 3 people in this thread.
