So it sounds like you are advocating 16GM of memory, am I hearing you right?
Both systems run RO2 just fine. Win 10 had some behavioral issues with Nvidia drivers for awhile, but that seems to have been resolved. The thing you need to be focused on is how much additional percentage of your hardware resources Win 7 and Win 10 will consume before any are allocated to RO2. THAT will be the only thing that may cause an undesirable change. They will consume somewhat more of your memory. So take that into consideration.
I am at this point. But each iteration of windows gobbles up a little more memory for it's own use. I adopted 16gb when Win 7 arrived. It gives the entire OS a lot of breathing room to allocate resources without pinching out the amount of game code which must reside in memory at any given time. The need for memory by the O/S and hungry sophisticated game code will only increase over time. There is no harm in having a generous amount of ram, both on the motherboard and on the GPU.
