Again, people need to dial back their expectations here. You aren't going to see cutting edge games running well through emulation. There is a reason Apple made such a huge emphasis on native apps, native is always going to run much faster.

They didn't demo gaming to suggest this is a great machine for gaming, they demoed it to show that it was possible at all. The previous version of Rosetta during the PowerPC->Intel transition was not known for performance.

If gaming is important to you and you want a Mac then you want an Intel Mac or whatever games are released for Mac ARM. Emulated games are not going to compete with native.
