Did some quick tests.
Sprite with bullet + fade. Before (111 stable)- C2 ~10400 sprites vs C3 5500 sprite at ~30 FPS.
After update (112 Beta) - C2 ~10 400 vs C3 around same as C2 ~10 000, but seems maybe 2-3% slower.
Bullet behavior on sprite (111 stable) - C2 ~ 11000 vs C3 ~9500. (112 beta) - C2 ~11000 vs C3 ~ 14 000
Did some extreme test. Sprite with fade,bullet,Solid,Flash,DestoryOutsideLayout,Rotate:
(111 stable) C2 ~7700 vs C3 ~ 1800. (112 beta) C2 ~ 7700 vs C3 6700.
When sprite has 1 behavior it is better in 112 Beta and in 111 in most cases, but if multiple behaviors are added, C3 is same or bit slower in come tests.
Just Fade on sprite, is around same in 111 stable and 112 beta. C2 - 15 000 vs C3 ~25 000.
Sine same in 111 and 112: C2 ~ 23 000 sprites vs C3 ~ 34 000.
Test are results with 30 fps, so when you try achieve 60fps, results maybe be different. Done it with my own tests to give some overview.
C3 peforming a bit slower is to do with C3 trying to match C2 runtime, so it is faster but doing extra work to match C2.
It seems really nice that C3 is getting better with every update.
