Physics and Game Lag with newer Corona Build (with Evidence)

Solar2D Daily Builds and Public Releases
#1

EDIT : - I have just tried creating a blank Physics game using the template provided with Corona and it appears to have the exact same problem.

Menus are fine, but as soon as a level with Physics appears (eg - the crate over the grass) the system slows to a crawl and I get a couple of FPS.

BUILD Version : CoronaSDK 2012.797

I posted this at the end of my other thread, but am reposting it here as a separate issue as I think it is unrelated.

Having just updated my Corona to the latest build and updated my app, I have found that something has gone wrong with the physics and frame rate somehow.

It works perfectly in the Windows Simulator, but when I build to device, the menus are all fine, but as soon as any scene with physics appears, it lags completely, playing at maybe a couple of frames per sec.

Any ideas what may be causing this? [import]uid: 131942 topic_id: 25702 reply_id: 325702[/import]

Just to clarify also - the app was working fine before I updated Corona - apart from slightly long load times between scenes.
But the physics had no problem.

It seems to have only been since I updated Corona to the latest build.

Is there a way I can undo this update or fix the problem womehow?
Or do I nee to completely uninstall and redo from start? [import]uid: 131942 topic_id: 25702 reply_id: 103914[/import]

Similar problem here.

After upgrading to the newest build, my game starts to lag when using physics.

This is on my phone using Android 2.2

On the tablet it seems to work fine (Android 4.xx)

When you build for device you have to choose only the min. version which is 2.2 (by default).

Ah cool. Ok, that makes more sense! Heh! [import]uid: 131942 topic_id: 25702 reply_id: 103962[/import]

My Tablet (Galaxy Tab 10.1) is on Android 3.2 and still has this problem.

Has anyone else had a similar problem at all?
Any news on what might be the cause?

UPDATE on this:

I’ve uninstalled Corona and rolled back to a previous version (back to 785 to be on the safe side).

My app is now working again which leads me to believe that problem must lie in the daily build (at least in the latest one).

So I’ll carry on with the earlier build for now. Please let me know if you manage to track down the problem and I can update again. [import]uid: 131942 topic_id: 25702 reply_id: 104079[/import]

I can confirm this problem too. Physics run slowly.
I have seen this problem on Xoom and HTC Desire.

No problem on Galaxy Nexus or HTC Evo 4G.

As mentioned above, for me the problem does not exist if I build with 796, but is certainly there with 799. [import]uid: 28534 topic_id: 25702 reply_id: 104806[/import]

#11

This seems to have been fixed in the latest daily 806. At least the problem I was having is now gone with this build. [import]uid: 28534 topic_id: 25702 reply_id: 105461[/import]
