Real Speed Of The Preview Window

Hey guys,

Is the speed of a game in preview (debug) window same as the speed of a game on mobile devices?
When I exported game for Windows (exe file) the game was 2x maybe 3x faster than in BB preview window.

Thanks.

 

The performance varies from device to device it’s even some games get some lag in mobile

 

Is it possible that the problem comes from my graphics card (AMD up to date)? The game in preview window is really slow, but exported version (win version, exe file) is super fast :/

 

Any ideas @Andy ?

 

Any ideas guys? @Andy, anybody?
My preview window - debug mode is runing 30fps, looks really slow and I'm using just original Runner Game Type ... the slow speed is the same for all game types

 

FIXED!
The problem comes with AMD graphic cards and V-Sync setting on Windows.
Go to your graphic card setting (AMD Catalyst Control Center), click on Gaming, 3D Application Settings, go to Frame Rate Control - Wait for vertical Refresh - set to Always off.
It will change the frame rate of the preview window from slow 30fps to realtime 60fps!
