Performance Issues

I’ve been playing AOE2 DE since it came out on my laptop. All of a sudden for the last month or so my game is lagging. Issues seems to be with my computer or the game itself and not my internet. Any idea’s on how to fix? When i uninstall the game and reinstall it works better for a couple games then reverts back to lagging. I have a good laptop I think. Any ideas on how I can improve this?

This is my laptop - Lenovo ThinkPad P53s - 15.6" Touchscreen Mobile Workstation - 1920 x 1080 - Core i7 i7-8565U - 16 GB RAM - 512GB SSD
