How do I speed up a UMG based project

OK so I’ve gotten creative.

I’ve used the Unreal engine to setup a UMG interface to enter all the information to run a combat simulation for the board game Eclipse that computes odds of winning in any given battle, but the packaged program runs fairly slow on most laptops; the calculation time is OK, but the interface is slow to respond to input.

project setup:
The project is 3 UMG widgets, the player blueprint, and a few data structs using the 3rd person template.

I call up the main widget in BeginPlay of the player blueprint and pause the game.

The widgets handle the data input and the player blueprint handles the calculation.

Any and all ideas are welcome, if I can save a few ticks here and there, they could add up!

Thanks!
