Does it play okay on your 1Gb GTX 285? (just read your system specs). I thought the minimum was a GTX 680?
Im going to go out on a limb here and say no it doesnt :P, look at anandtech they did a benchmark of assassins creed and it runs like an absolute dog! I cant even play it on low @ 1080p with my 7950 boost as I get less than 30 fps in most places its just horrible to play and its also horrible to look at! Black flag was the polar opposite for me, it looks solid (not crysis but certainly pretty enough) and ran silky smooth.
This game runs like a dog its clear that it was rushed out the door for the holiday season, it needs another 3 months at least to get it running on ACCEPTABLE HARDWARE. Who would have thought you would need a GTX680+ just to play on low at 1080p… the consoles do it okay for the hardware they have but its still piss poor.
