Hi
U-48Kriegsmarine,
I have an HP laptop too:
CPU AMD Turion 1.9Ghz
GPU nVidia GeForce 7150 (integrated, 128Mo dedicated)
2Gb RAM
With the difference that I use a dual boot Vista/XP, XP being for gaming (I need the maximum of those 2Gb of RAM).
I can run SH3 + GWX3 Gold + OLC Gold (16km) without too much trouble. I get around 15-25 fps on a calm sea, but admit it can crawl down to 8-12 fps when in port / convoy / storm. It' still pretty playable. And in no way have I encountered what you have. May I ask what your settings are for your GPU (nVidia panel)?
PS: First post, hello people! And I apologize for being such a nasty lurker (have been registered for a couple of weeks so as to plunder your great download section

)
