I've been doing some tests with the new version 1.14 and the stuttering behavior changed.
In this new version, it stutters all the time when I record a game that's running in full screen (dx/opengl mode). It doesn't matter what the settings are.
But if I record the game that's running in windowed mode (still dx/opengl) it doesn't stutter anymore. Exactly the same settings and resolution as the full screen. This is an odd behavior.
Why is this happening? It's irritating if I have to run in windowed mode just for recording purposes.

I hope this gets fixed.
I know for a fact that my computer is highly capable of achieving this.
