Low FPS on high end system - anyone else?

It could deal with windows 10 and direct x 12. Who knows

 

Having the same problem as atomic fish, good hardware but low framerates, even in single player quests. Would love any advice or fixes. I tried Jeinx's suggestion of making sure I told the application to use my GPU, still looks like the game is running heavier on the CPU than the GPU - just sitting on vanity island my CPU can go up wards of 60%, but my GPU doesn't seem to go over 40%

 

As with most RTS, this game is more CPU then GPU intensive, as it has to constantly keep track of hundreds if not thousands of actors and how they all interact with each other at any one time. While I personally rarely have issues with the framerate, there was one Roman quest, second-to-last out of the roman questline where you have to defend your base for 20 minutes, in which the last 3 minutes was spent at 1-2 fps due to the thousands if not tens-of-thousands of idle units in the enemy base. Fortunately at that point I had a solid collection of towers to kill everything that approached, but it was pretty bad.
