Nah this isn’t true. If you gave the devs a free month I’m sure they could optimize the hell out of things. The issue is there are deadlines and higher priority items. You can technically play cities 2 unoptimized at a lower fps and graphics setting, you’ll have a much worse time playing it if features are incomplete and full of bugs.
They simply didn’t have the time to get to optimization
Also played a ton yesterday. Biggest issue I had was a small stutter every 20 mins or so when zooming in or something. Maybe with certain hardware it’s having issues, high end cards or something? Overall I’m having a great time
