On average, you can expect between 10 and 20 frames per second. The minimum I got was 7 and the maximum 40 frames per second.
You need the Intel GMA Reg Modder utility.
Run it as Administrator, and search for the pop.exe file, set it to run on Software Mode.
Set the resolution to 800x600 (or 1024x600, using the Universal Widescreen Patcher - if the HUD is out of place, exit the game and then start it again, that should fix it).
Then choose high texture quality, medium effects quality, bilinear filtering, no shadows, no water effects and no v-sync.
How much I played
From the beginning of the game to The Baths.
SHOULD YOU PLAY IT ON A NETBOOK?
Prince of Persia Games are awesome. And the performance on a Netbook doesn't absolutely suck.
