Screen tearing if playing games at 30 fps, no screen tearing while watching movies at 30 fps

[Blitzvortex]

When I watch 30 fps movies I get no screen tearing, but when I cap my frames are 30 in game there is tons of tearing. Even at 70 fps on battlefield 1 I sometimes get tearing (no v-sync on).

It doesn't matter if the GPU is rendering faster or slower than the monitors refreshrate. If you're getting an fps that isn't a multiple or a 1/x fraction of the monitors refresh rate there will be tearing.

If you want to be rid of it you can enable vsync and suffer the input lag, or get a gsync/freesync monitor.

The best way to put this is this:

A. Games can run without v sync or with v sync.
B. Movies and non gaming applications ALWAYS run with V-SYNC. Hence the no tearing.
