   hi,
   my master thesis is about sgx chip. i need to test it performance on iphone 3gs.
   as the fps never goes beyond 60, it really restricts my tests.
   I saw many posts talking about inconsistent fps between 60 and 40.
   beside this problem i also hope to know if there is a way to get animation faster than 60fps.

   zodTTD put a video showing its program running at over 150 fps, but i didnt find anything telling people how to do it.

   can anyone help?
   thanks alot

   It goes never over 60 fps because it is waiting for the vsync of the display.

   i guess they mean that their game loop iterates 185 times per second which also calls the code for drawing.
   But due to the vsync it's only shown 60 times on the screen which they could mean with: (60)
   Don't ask me what the (0) stands for :-)

   Maybe it makes a difference that the phone is jailbroken? I'm not sure if there's a say to override the vsync on the iPhone otherwise. There was a thread about vsync awhile ago - http://www.cocos2d-iphone.org/forum/topic/849#post-5024

   This may well be the number of Pokémon he's captured. (Sorry, couldn't help it ^_^)

   Yeah, since this is an emulator I'm guessing 185 is the framerate the emulation is running at. The screen is not actually being updated 185 times per second. As far as I know there is no way to disable Vsync.
