(RESOLVED) Harmony 12 - OpenGL Lag - 30% CPU usage, 2% GPU usage

I’m running ToonBoom Harmony 12.2.1, and I’m TRYING to use my Nvidia Geforce GTX 1660 SUPER, but it’s insisting on eating up 30% of my built-in Intel Core i5-9400F CPU and only 1-2% of my Nvidia GPU.

My Tablet is a Wacom Intuos Pro.

I don’t get it. Why is it lagging? I’m only using one audio layer, one camera-with-peg-layer, and one drawing layer, for the record, and it’s not even very complex - just some sketchwork while I prepare for a more detailed animation. The scene is 650 frames long, but that shouldn’t be an issue, right (given the simplicity of what’s there)?

UPDATE: I wound up fixing the issue after re-installing my Wacom Tablet Driver and going to my Nvidia Control Panel and telling ToonBoom to run on the Nvidia for all OpenGL-related processes. No idea which one was the key, but I’m thinking it was the Wacom one, if I’m being honest.
