1) Im upgrading my SSD to a larger size soon and instead of doing bootcamp again i was thinking of using parallels for windows/gaming for easier use. My question is how well does it perform with gaming?? No lag with high end games on high settings?? I have rMBP mid 2012. 16gb RAM, 2.3GHz i7, Intel HD4000 as well as a dedicated NVIDIA GeForce GT 650M w/ 1GB VRAM. i have no problem with any games via bootcamp and can run them all on high, but don't know the level of decrease in performance of parallels. 2) Also, How does partitioning work on parallels?? do you still need to set off a specific amount of HD space?? can you change the amount afterwards?? or does Mac and windows share the entire SSD for parallels? Thanks!
