I use the standard Kodi and player and output 24p content at the native rate to my JVC projector. This has always worked fine for me up until last week when it suddenly started running everything at a very low framerate. I do have a thread going in support with error logs and all of that but it likely won't be resolved soon so I thought I'd try to get a workaround going myself.

Some of the threads I read sent me over this way. Do you think trying out DSPlayer would have a shot at resolving my stock Kodi playback issue?

You could try display mode switching with madVR. There is a DSPlayer/madVR guide linked in my signature. Be prepared to spend a lot of time reading; it is not a simple process to switch over. I would start by turning off refresh rate switching in Kodi and using madVR's "display modes."

If that works, continue on with the remaining set up.
