Does the player have V sync yet?

[Ray Beez]

What do you mean by Vsync? Is v sync the issue where the screen drawing is split when objects move horizontally?

Correct. When a native application has direct access to the hardware (or via an API like DirectX) you can choose to sync graphics drawing with the monitor refresh rate such that you do not update the screen in mid-screen refresh, as that causes horizontal tearing (most visible in side-scrollers).

There had been whispers of possibly getting something very close to this in the last release of 10.x .
