problem with Empire campaign

[shikun]

the game is playing smoothly in the original campaign. but when i install the Empire campaign it lags like hell. i mean it's not even playable. does anyone know what that problem might be? i might have been installing it incorrectly.
the textures and everything works fine. but it lags like hell..
i just copied the installed original Lugaru content to another folder (which is named to Empire) and copied the Empire content to the "Empire" folder, and overwrited it. am i doing wrong?

my computer:
AMD Athlon 64 X2 Dual
Core Processor 5000+
2.61 GHz, 1 GB Ram

i'm not sure about the GFX card. but it's supported with DirectX 10 in Vista. so it shouldn't be a bad GFX card .

Is the frame rate really low? If so, turning off the skybox and lowering the view distance will help. It's in the readme. I dunno though, I feel like your computer would handle it fine. The only other suggestion I have is to try reinstalling it.

hmm. my computer should handle it without lowering anything. i don't know about the framerate. how do i check the it?
i might just reinstall it..

I you are in debug mode the framerate shows up in the corner of your screen. You get into debug mode by changing the "debug" value in the "config" document from 0 to 1. Goodluck, I hope you get it to work.
