Groove Agent 5 - Previewing one shot/instrument samples is frustratingly slow

When I go to the Instruments tab in the Groove Agent 5’s Browser to browse for individual one-shot samples, the experience is way too slow. Most of the times when I scroll up/down (using keyboard up and down arrow keys) for previewing the samples I don’t hear any sound. Sometimes I hear it but most of the time I don’t.

I reinstalled Groove Agent 5 but no luck.

Is anyone else facing this problem? Or am I missing something?
