BF2S Forums BF2 Spiking, who knows, ive ran out ideas..

Ok ill explain this as good as possible in the hope some1 could help me out here.

When i play battlefield 2 and i move (WSAD) and at the same time move my mouse i start spiking massively (i see in shocks, very fast shocks but still its very very annoying) Maybe somebody has heard of this before..

Anyway what i have done:
- Update my drivers (at nvidia site)
- Reinstall the game (although its always bin like this) but still it only happens on this game (not when i play cod4 for isntance)

I have bin altering the usersettings abit, i dont really know if that mite have caused anything to happen. this is what i use atm:
SettingsManager.boolSet GSClPunkBuster 1
SettingsManager.floatSet GSDefaultLatencyCompensation 0.030000
SettingsManager.boolSet GSExtrapolateFrame 0
SettingsManager.U32Set GSExtrapolationTime 400
SettingsManager.U32Set GSInterpolationTime 40
SettingsManager.U32Set GSPerfLogAtPlayerCount 30
SettingsManager.stringSet GSPlayerName "#t[D]s E-I-U-BENJAMIN"
SettingsManager.boolSet GSShowNetGraph 0
SettingsManager.boolSet GSUseObjectCache 1

It cant be because i have a bad pc because its MORE then enough to run that game even on highest graphics.
Specs:
Intel Core2 CPU 4400 @ 2.4ghz
4Gb Ddr2
Nvidia Geforce 8800GTX

i dont really know anything about chipset etc, but there shouldnt really be a problem here anyway.

Thanks for reading, and in the hope for a fast responce
