Long load screen/terrible framerate

[DeltaTactical]

Firstly, I apologize if this has already been asked/answered. I searched, but couldn't find anything.

My hardware is as follows,

ASUS G1Sn-A1 Notebook
Intel Core 2 Duo T8100 @ 2.1 ghz
4 gb of RAM (DDR2 @ 800 mhz, I believe)
nVidia 9500m GS

I'm running Windows XP x64.

I can run BF2 at max settings no problem at 1920x1080, pulling in a framerate average somewhere between 40 and 60. I understand PR takes a lot more juice, but I'm having a hard time even playing it on my PC. After I started playing some LAN matches to learn the ropes, I had to set my video settings to medium, at a resolution of 1024x768. Even then, my framerate is usually somewhere in the low 20's, not much different from when I had it maxed out. I also find that every 5 seconds or so, I get a huge drop in framerate. If I'm inside a building (where my framerate is passable), I'll go from 35 to 15, and then back to 35 which causes my game to hang for a second or two. All in all, its pretty unplayable. I'm gonna try going even lower with the graphics settings, but it already looks pretty terrible so I don't know how much enjoyment I'll get from it.

Also, my load times are CRAZY. I'm talking 15-20 minutes to join a multiplayer server. And that's after my shaders have been optimized. That is a huge deterrent.

Is there any way this could be fixed? Or am I doomed until I build a new PC? I have already tried running BF2 Cleaner to no avail. Also, no need for GameBooster or anything like that, my operating system idles with very little resources.

Not too informed on Nivida cards but check your bios and make sure the video card gets the largest data block it can. That may help with the bottle neck at your gpu(video card).
