I am by no means an expert and someone may well correct me here, but I am guessing that perhaps although your card has the capabilities for certain things, the program is telling you that maybe to my mind that the memory on your card is not enough
I maybe and to be honest I hope I am wrong for your sake.
I am currently running it to see what it says and then I can interpret it better, although my system will be fine, so hold tight and I'll post back with anything else I find out
Is your graphics card an onboard one? I don't really know what it is, I am guessing its onboard, if so then I think that might be the problem, again don't take my word for it though, anyone else know, help me I'm stuck
