so many problems with this
a) wrong section, Q&A or general please
b) notice that word "leaked" in what you said? it means this isn't OFFICIAL, which means it likely ISN'T the final release, so it's bound to have at least some bugs.
c) ryanza lagfix is placebo and awful and doesn't work at all (on top of that, ext2 is a bad choice)
d) if you understood how/where the lag was coming from, you'd know why voodoo is "necessary" on 2.1
e) the aria is built EXTREMELY different from the captivate, it's like comparing the iphone to the nokia n8... yes they're both android, but they're built different which leads to complications
f) voodoo is not yet available for 2.2 because we don't have source code for 2.2 (again, if you knew how voodoo worked, you'd know why it wasn't instant)... we can hack it in with initramfs, and there are people working on it... but it isn't top priority
g) and shockingly a SMALLER piece of hardware with a SMALLER resolution made by a company known for making quality android phones runs smoother? shocker. honestly.
h) if you actually had any other real world interactions with other android phones, you'd know the lag is occasional but not unusual (hell I've seen just as bad or worse on the droid x before)
i) I suggest you read, read, read, search, read, read, and think before you make posts like the above (why on earth you thought this belongs in development is beyond me)
