So I tried on Canurunit and my cpu meets all recomended specs cept for graphics card
I have a ATI Radeon HD 4650 1GB, how far off is that from a recomended card? How much a graphics drop will I notice? Will I still be able to play on the highest settings?
(the rest of my cpu blows rec's out of water, quad core, 8gb ddr3 ram, etc)
First of all, the recommended system usually isn't enough to run at maximum settings. That said, that card is just a 4800 with a lower clock speed, so you'll be able to use whatever features that card supports, it will just run slower. The 4650 runs Crysis on medium settings comfortably, to give you some idea.
This is just guessing, but I think the more important issue for this game will be the cpu and ram.
