Okay, so I know this is only my first post. And I don't even own an Evo yet
But I've been following the forums and news about the Evo since it's release (gotta wait until July 11th before I can leave AT&T and trash my iPhone... could time possibly pass any slower?) The frame rate and UI lag has been a concern for me. Even then I know it won't stop me from buying one.
Anyways on to the point of my post..
Regarding gaming, its a problem cause the fps fluctuates during any game. If the screen is capped at 30 fps then during gameplay it can often drop much lower than 30 cause of the artificial limitation. Whereas if there is no cap, a game might be at 507 fps then drop down to 30 during intense scenes. But starting out already capped at 30, it might drop down to 15 which might look really bad.
I don't know if the Evo would work this way. But I know with my gaming rig I get almost 400 fps on most games. With that high of fps I get screen tearing. So I use vsync to cap my fps at my displays refresh rate of 60. Even with vsync capping my frame rate it never drops below 60 because my video cards a capable of a much faster rate.
I know I've read the Evo is capable of around 60 fps. I would assume because of that fact it would be able to stay at a steady 30 fps even with action on the screen. Could it be possible that the gaming issue is just because of bad optimization? And not because of the phones frame rate cap? I know Kedar said ExZeus Arcade runs smoothly but Raging Thunder 2 lags. I've owned both those two games on the iPhone and I know ExZeus is a much more intense game then RT.
Of course if optimization is the case then I have no idea what the UI Lag's excuse is.. But with as bad as my iPhone 3G lags I'm sure I won't even notice it
Hopefully with Froyo it disappears.. If not I can more then live with it!
