Anyone with poor specs tried the demo?

[Medieval Assassin]

Sigh...
POOR specs, not P4 2GHZ machines,
Oh well, I now need to get a new motherboard, A new processer, a gig of ram, new speakers maybe, and maybe a better video card

[Alexander the Pretty Good]

Is this poor enough:

Compaq Presario 1525
P4 2.4 Ghz
512MB RAM
Directx 9.0
XP Home
32MB Graphics card - ATI Mobility Radeon 7500

I ran the demo, kept getting error message:

Insufficient video memory to load requested texture set

until I cranked down the video settings REALLY low.

And it still wasn't pretty. On the tutorial, there were patches of grass that reflected the sky ( ) and some units kept dissapearing, especially the Roman archers. Sometimes either the horses or riders would disapear as well. The Roman general never appeared colored in, and sometimes the other units didn't, either.

The Trebia battle was terrible. Everything was spazzing out, and it looked like there were soldiers everywhere (was there too much detail like trees and soldiers, maybe?) and I just couldn't bring myself to play it (I did make my elephants charge suicidally; none survived).

I need a new graphics card. Can that be done on a laptop?
