yes that is real maintaining 27-40 fps is impressive on that system but still ubisoft is a bad port to pc it would've done more if it was optimized well enough.
Hello? 1024 x 768? That's 0,7 mipix. Where fhd [1920 x 1080] is 2.07 mipix. You need three times less computing power to run the game at that resolution, so yes, with beefy Q6600 and GTX 560, which ain't that bad at all, it's totally normal.
