Small update this time. I received some feedback that booting up the game almost immediately causes the computer fans to kick on, indicating some pretty intense resource usage. I looked into it and observed 90-100% GPU usage when running my game X_X. This didn't make sense based on the relatively simple game scene and further this didn't improve even when the game sits idle. 

So I went down some optimization rabbit holes, but in the end I found a few unreal settings which needed to be updated for my game. Most notably, I enforced a framerate smoothing with a much lower max framerate. This prevents the computer from attempting to render frames as fast as it possibly can and significantly cuts back on the GPU usage. I also simplified my lighting setup and baked some of my lighting since my scene is largely stationary. Hopefully this creates a better experience for everyone, and keep the feedback coming!
