Developer Kushdeck's Ice Cream Sandwich port brings speeds like I've never seen to my HTC EVO 4G. As with Evervolv ICS, Deck's ICS pre-alpha 3 is a work in progress with the same limitations (no camera, no WiMax), but man, is it fast!
Transitions between pages of apps flow fast, menus pop up when you touch the button (as opposed to right after), programs appear as if thrown to the screen, and my EVO 4G running 998 MHZ is seriously a contender to the dual-core EVO 3D running 1.5ghz in terms of how it feels. I installed SetCPU on the phone just to check if it was overclocked, and it was not.
Looking under the hood, you'll find that it runs on Tiamat's 4.1.0+ kernel, the same as Evervolv does, so evidently in a few days of ICS porting development, Deck managed to stomp out that whole slow-motion ICS thing.
There are very few visual differences that I can tell between Deck's ICS and Evervolv, which is understandable as the main work right now is in getting things to work. Deck's doesn't feel quite stable to me, though. It runs like a bat out of hell, so perhaps it's just quicker to run into problems than Evervolv was. But for browsing, dialing, web surfing, this ROM's a charm.
Before checking out this ROM for myself, I was a little worried that the EVO 4G would be a little too slow to run Ice Cream Sandwich. Needless to say, I'm not misguided by that notion anymore.
