Lag on different devices

aditya

Checking with gideros player for the devices below. Works great on the nexus, lags a lot on every other device.

Box2D:
Static Tileset: 1
Moving Objects: 19

FPS:
Nexus 7: 60
Sony Ericsson Live with Walkman: 40
Samsung Galaxy Ace: 20

Memory Usage:
Nexus 7: 563
Sony Ericsson Live with Walkman: 566
Samsung Galaxy Ace: 565

Is this a problem because of the number of active moving objects at a given time or something else?

I remember the Vertical Stack example (coming with Gideros installation) runs really slowly on armv6 devices. Because armv6 doesn't have (or optionally have) hardware floating point support. (Samsung Galaxy Ace have armv6 CPU, I don't know Sony Ericsson Live with Walkman)

I can recommend removing armv6 support by removing libs\armeabi folder before publishing your game.

Sony Ericsson Live with Walkman "phew", is armv7.

atilim

Yes, you're right. SELWW has Qualcomm MSM8255 Snapdragon. How does Vertical Stack example (80 bodies) work on it?

aditya

Tested it a few hours back with 20 instances of b2d dynamic body, it still lagged. Don't have the device right now, will check tomorrow and report.

aditya

Yup, lags with a fps of 6.

@aditya oh... I'll be glad if you can you run AnTuTu (and maybe Quadrant) on this phone and paste the results here. It's interesting that an armv7 device performs that bad. For example, Galaxy S II can run Vertical Stack with 60fps.

AnTuTu on Galaxy S II:
Total score: 10515
CPU integer: 965
CPU float-point: 722

AnTuTu on Nexus 7:
Total score: 13284
CPU integer: 1960
CPU float-point: 1291

Total Score: 4389
CPU integer: 361
CPU float-point: 206
