FPS lag :(

[Dreadnought1984]

Hi guys, I have this frustrating issue with PR. renderer.drawfps 1 will drop to 15.0/66.7 and stay there and I can barely move. It sometimes starts after playing 2 hours but has happened as soon as playing 10 minutes. Restarting the game doesn't help. Only restarting whole computer does it. But it only affects PR. CS:S will still chug along at around 60.

I thought it could be Punkbuster lagging me, but I'll open task manager and kill punkbusterA.exe (or however it is spelled) and PunkbusterB.exe and try to play for a minute before it kicks me, but this has no effect. Punkbuster has been manually updated often.

It's not some other process like a scanner or something BF2.exe is the only thing using cpu time (other than task manager.) I do not run any bloatware and I'm religious about keeping Avast! and Spybot up to date. I thought it could be a heat issue, but every thing is no hotter that it is with any other game. (And besides this thing just flips on like a switch and restarting the game has no effect; not something you'd expect with a heat issue.)

I don't recall this happening in vanilla, but I'm not certain because I never played it as much as I played PR. I'm just wondering if anyone else has an issue.

Thanks for any suggestions anyone may have.
