My Mother has a 13" white MacBook running OS10.6.8 and wants to play Flash games. However, I have tried to install a newer version of Flash (17.) but the games and videos are choppy/flashing. I tried to find specs for older versions of Flash without any luck. Quite annoying really that the specs are not listed on the downloads page for older versions. So which version did the specs change from 64mb to 128mb VRAM.
