Stuttering and Massive Frame Rate drops during transitions in preview

hey everyone, this problem has plagued me when working on Vegas Pro 16 and now it continues with Vegas Pro 17. Usually the video preview will run fine but the moment it hits a transition, not only does it not show the transition but the performance tanks. I've done a bunch of research, tried all sorts of troubleshooting steps such as raising the dynamic RAM preview, lowering the dynamic RAM preview to 0, going into the hidden "Internal" menu in preferences and turning OpenCL/GL Interop to FALSE, disabling resampling, setting the priority to Vegas to High in Windows task manager, and of course setting the preview resolution to Auto. Nothing has fixed the issue and with me trying to use this software for more professional work, it's really starting to hinder my workflow.

Is there some trick that I'm missing? There's no way the software is meant to run this poorly, right?

My specs are below, any help or suggestions would be greatly appreciated.

CPU: Ryzen 2700x

GPU: nVidia 1080ti

RAM: 32GB 3200 DDR4


Thanks as always.
