I just bought an Acer 5610z laptop. Its not the best, but hey it was cheap. It is also better than my desktop system spec wise.
specs: Pentium dual core 1.7/1.7
2 gigs ddr2
160 gig hd
Mobile Intel 945 GPU
Running windows vista home premium 32 bit
I figured the game would be a little sluggish due to the shared video ram, and the fact its running Vista

But i have the glowing asteroid problem, and this isnt an ATI chipset.
I am thinking of dual booting this laptop with windows XP to see if it will make any difference performance wise, and fix the glowwy rock problem, but i just want to know if others with similar specs have the same issue.
