Sorry but any game can stutter on any tablet if the author didn't tune for that tablet.
You used short hand such as "Cm10.1" and while I know what that is, you are asking a lot for the uninitiated.
OK, because the office is working on porting apps I have access to the Kindle Fire HD, Nexus 7 and a lot of tablets. But we omitted the Nook because it was not open to apps like the others.
If you are asking for rooted tablet performance, I'd post in the forums that talk about rooting and more.
-> You seem fixated on speed. Why not skip the Nook and get a nice Nexus or Samsung?
I need opinions on which tablet to buy. I want one with external card option so Ive narrowed it down to these 2. The nook HD sounded impressive with a faster processor and higher resolution. Then I heard it stutters in games and some apps and it actually runs slower and less smooth then the galaxy tab 2 and also the speakers suck. I also like it has a regular OS. So is the Nook HD still slower with recent updates. Does it run any better with Cm10.1 running from a card instead of the proprietary Nook interface? Will movies look good on the galaxy tab 2 even though its not HD? Most of the movies I watch will probably not be HD anyway but some games will be. TIA.
