Graphics Settings of AC 3

Hello,I've just installed AC 3 it was lagging so i changed the graphics settings then it worked well but my PC is showing messages time and time again that reads like "Convert Windows Theme to Basic" maybe this is due to overload on GPU can anyone here tell me settings of AC 3 for HD 2000 and also give me DL link or tell me name of a good GPU Monitor.

Thanks

HD 2000? man please buy even a 3-4k card.. FFS.. :@

increase the shared ram for your system for the GPU in your bios.. atleast share 1GB of it, to give the card some breathing room.. i am guessing less Vram is the issue here..

You should stick to playing on consoles. PC gaming ain't a cheap hobby.
