I took the time to play the game on an M1Pro (10 CPU cores/16 GPU cores).

Basically it runs quite well. But the x64 on Arm emulation is clearly noticeable.

On the one hand, as already expected, in places with many players. Here, a PC also needs a corresponding CPU performance for the game to run smoothly. I noticed this years ago when I did a major graphics card update on my PC and wondered why there was hardly any improvement. Only after upgrading the CPU was there a very noticeable improvement. From many years of experience with many emulators, I also know that native code runs on average 5-10 times faster than emulated code.

In addition, the dynamic compilation is very noticeable. Directly after logging in, the movements are very often stalled at first. Later it becomes less, but it still happens from time to time. Especially after area changes. These hangs are a typical sign that code just needs to be compiled before continuing with the execution. This is the case with all emulations with dynamic compilation.

My conclusion: A native Arm64 client would noticeably improve the gaming experience in the two previously mentioned points.
