I have quite an old PC, so it gets VERY laggy with lots of units. Which graphics settings should I target to reduce lag with many units?

Edit: best if it minimally impacts graphics

I'm playing AOE4 on the XBOX app (PC) with keyboard and mouse. This only started yesterday (when I first played the DLC) where it sometimes takes more than 30 seconds for a message to be sent. Normally it's only one second or half a second, but now it's getting very long. Is this a server issue or internet?

Edit: for more information, I'm in the EU
