I'm currently not at home and run KSP on a very common late 2011 entry level notebook configuration Intel Pentium B950 (sandy bridge architecture) - 2.1 gHz 4gb DDR3-1333 (single channel mode) Intel HD Graphics (slightly slower Version of Intel Graphics HD2000 found in i3 CPUs) The Game runs OK until you try to field very large Designs OR try to look at the ocean - seems like the Intel IGP doesn't handle the water shader too well. Still looking forward to have access to my main machine (i5-2500k, 460gtx).
