According to this blog post https://www.parallels.com/blogs/windowsgames-m1mac/ AOE 2 DE is shown working in single player mode (With AI players). But this is not Online (Steam) multiplayer. The moment you join a multiplayer game, the game desyncs. This happens either spectating the multiplayer game or playing. I've tested on the latest Windows 11 ARM and Windows 10 ARM. Latest Monterey 12.0.1. Parallels Version 17.1.0 (51516). Latest AOE 2 DE and Steam. Tested on a fully loaded MacBook Air M1 and a 2021 Macbook Pro M1 Max with CPU and RAM maxed out. When the game launches, it gives me a warning that the system has less than 1GB VRAM. Could this be the issue? If so, where can I adjust it?
Got it to work with Crossover, but have not found something about a solution for Parallels. Singelplayer runs much better with Parallels.
