We’ve almost completed our first alpha release version of SuperB - newest title from rubycell but there was a HUGE issue with particle’s performance.
Our game on iPad - iPhone 4, has droped from 59-60 FPS to 29-30 FPS right after we turn on some SIMPLE-and-SHORT particle effects ( set EmitterRate = 10 or something like that).
The same issue on Android 1Gz like SS Galaxy S2, HTC Nesux 1, LG Optimus One, no problem on SS Galaxy S2. However, on Android devices it droped sightly, from 35-40 to 25-30.
We’re tried everything from pvr texture, rgba 4444 pixel format, disable VBO for particle to switch architecture to ARMv7 or ARMv6, but still haven’t got any improvement at all
Have you got this issue with your game? Any suggestion to fix this kind of performance drop?
