Perry Rhodan Immortals of Terra Problem

[K515]

Hi. Immortals of Terra installed ok onto my laptop's external hard drive (witch is connected to the main PC by a FireWire cord) but when I try to play it the intro sequence plays just fine, but when the gameplay starts, Perry moves very jerkily just a couple of steps as my mouse is extremely sticky as I move it, and then the game crashes to a black screen. Here are my laptop's system specs:

Laptop System Specs:
OS: MS Windows XP home edition (5.1, build 2600);
System manufacteruer: Hewlett-Packard;
Model: Presario x6000 (PK247AV#ABA);
BIOS: ver 1.00 Parttbl;
Processor: Intel Pentium 4, 3.20GHz (2 CPUs);
Memory: 1278MB RAM
Page file: 208MB used, 1421MB available; I think this changes
DirectX version: DirectX 9.0c (4.09.0000.0904);
Laptop display specs:

approx. Total Memory: 64.0MB;
Current display mode: 1024 x 768 (32 bit) (60Hz);
Monitor: Default monitor;
Now laptop display driver specs:
Main driver: ati2dvag.dll;

WHQL: Logo'd: n/a;

Any help would be appreciated as I'd really, truly like to be able to play this game.

I think the graphics card isn't fast enough.

I think the graphics card isn't fast enough.I had a similar problem with my graphics card which is a ATI Radeon 9800. My problem got solved by an upgrade from the ATI webpage. Perhaps you need an upgrade too.

Though a firewire port should be fast enough, I don't recommend installing games like that on external drives.
