[2022] Snap crackle and pop. Anno 1800 slow down and buggy after 2 hours of gameplay

Hi there @darrentemp1! Thanks for reaching out, I apologize for the delay in response.

Thank you for those screenshots, they are really helpful in understanding what's going on. Question for you, what is the run time for your CPU? You can check this by clicking CPU in task manager, it will show at the bottom. If it's high, I recommend restarting your PC to reset the run time to 0. Shutting down your PC or setting it to sleep will not do this, you need to restart.

Also, does this occur within all save files, or just one? Do you have a fresh game you can test this issue with?
