Hi all,

I discovered that after window resize on Win (VS2010 debug mode) and on iDevice after app folding with Home button, physics sprites slow down significantly. I'm not sure this applies to all physics sprites, but 100% to sprites with velocity driven by ago::SetSpritePhysicsImpulse.

Does anyone can reproduce this?

It could be that you need to setPhysicsScale after a resize. In Tier 1 the window size cannot be altered while the app is running, perhaps there are other issues caused by resizing too?

baxslash, it could be, but I cant figure out why iPad home button also affects physics sprites - this makes impossible to restore proper gameplay after folding app to background in iOS 4.2 and above

I'm not so good to xcode|C++ to code home button press to call paused gamestate, no ideas...

UPD: not only trying to resize window in win, but also dragging window title causes the same. I'm confused.

UPD: SOLVED: added StepPhysics() before Sync();
