A Rambling of an old man,
seeing we are talking about Aero and all that
I wonder turning off Aero for weak processors, might help on the game front, that if you cpu limited?
well not just for the game front, but anything that requires a litte extra from the cpu.
so i ponder and pause some more, "is that a bad thing!" apart from the 1990`s Look of life?

Desktop looks plain and very retro, and the I7 ticks over nicely,
39 (With Aero off) Win7 Lets do the Time Warp Edition
For me i just leave my Aero on,
1) my system can cope, and 2) love the gloss..
