|
The demo simply draws a vertical bar moving across the screen at constant speed, but deliberately rendered at a variable frame rate.
|
|
|
|
The min and max frame rates can be manually changed at runtime, by step of 10 fps and with a min of 10 fps.
|
|
|
|
The demo also allows to toggle V-Sync on/off.
