Launch Rekordbox with OpenGL / DirectX disabled, or something similar

Hi,

There was a topic somewhere which advised setting Rekordbox to launch with some kind of graphics setting disabled, I cant remember if it was OpenGL or direct X or something similar. It involved editing the rekordbox settings file and changing a value (windows). Can anyone help point me in the right direction as to what this was? Rekordbox runs a heck of a lot better on my laptop with this setting changed, however a recent update of rekordbox seems to have changed this setting back and its now no longer running as well (flickering waveforms every now and again etc).

No comments advising updating drivers etc, they are all on the latest.
