So my system spec is:
Vista Ultimate SP2 - Tweaked unnecessary services, not using an aero theme.
AMD Athlon X2 6000+ 3.0 Ghz
4 gigs of ram (actually 3 at the moment, but thats extremely temporary)
Nvidia 9800 GTX+ 512MB
Its definitely time for a new machine, but this is what I have to work with at the moment.
So right now I default to com_maxfps 125, on a few maps my FPS dips below this level and then I just choke it back to 76. However occasionally I'm finding that my frame rate begins dropping even below 76 capped ( Most recently on Goldrush ). Which doesn't make a ton of sense to me given that on other maps I'm throttling at 125 without a problem.
It seems to be related in some way to the direction I am facing in game as if rendering into the distance was the problem. So I decided to try tweaking r_lodbias and r_lodscale. However these didn't seem to really help in any way. I originally had r_picmip at 0, then 1, and now 2 which didn't seem to have a serious effect on my frame rate one way or another, and didn't help me keep my cap either. I've really got no idea at this point, if I can't diagnose whats causing the drop in FPS I can't really fix it. So anybody with any idea to try, I would be extremely grateful.
I would like to keep my resolution at 1680x1050 if possible, but if you think my system can't handle it I'd be happy to give adjusting it a try.
Note: My cfg was written in notepad with a monospaced font, so it might not look very organized if you open it with wordpad.
