Zoom and Pan erratic in large game end stage

Playing the "Random 10 Player - Multi Star" map. I play TEC Enclave and make extensive use of the Garrison Recruitment Center to add garrisoned ships.  At some point as my empire expanded, the zoom and pan became sluggish and began jumping from a view of the planetary region all the way to the farthest out zoom showing the entire galaxy with just one step of the mouse wheel. Similarly, attempts to pan would drastically overshoot. If I pause the game, then all works fine, but the space bar pause is also only sometimes detected.  Seems that the game is just too large and is bogged down on my system, but I have 128 GB and 32 cores (Intel Core i9-13980HX) and am using an NVIDIA RTX 4000 Ada Laptop GPU. What can I do?

I have experienced similar behavior on small maps/games, but never this bad.

Thanks,

Davy
