Will SL run on a Lenovo Z50-75? It has an AMD Radeon R7 with shared graphics memory, but the system requirements for SL mentions ATI Radeon 9500 or better. All other specs seem to be in the recommended range. So from what I read below, the R7 is better than the 9500. Why can't they name these so you can easily tell? I'm not looking for screaming performance (moving shadows are nice, but not necessary, at least to me. *grins*)
