Slight keyboard lag in Windows 11 ARM?

I don't think this is really a bug, it just seems to be an unavoidable characteristic of running Windows 11 for ARM under Parallels on an Apple Silicon Mac. I'm running the latest version of Parallels 19 on a Mac Studio M1 Max with 64GB of memory. Everything works fine, the only slight annoyance is that there is a very slight keyboard lag when I am touch typing. You will probably not even notice it if you are not a fast touch typist, but if you are you will have a feeling of a very slight sluggishness. It isn't really enough to hinder work.

The effect is mostly psychological: The only way I can describe it is that there is a subjective feeling of more "effort" while you are typing. When typing on a normal Windows machine, or directly under MacOS, typing is instantaneous. In Windows 11 for ARM under Parallels 19 I always have the feeling that there's a very slight delay after each key press

Again, it's not really enough to slow down work in any way, but it is subjectively distracting enough to be annoying. Does anyone else experience this?
 
I have Parallels 26.2.1 (57371) and I just created a Windows 11 VM yesterday on my M4 powerbook. I don't notice any keyboard lag at all - everything feels extremely fast.
 
Keyboard lag in Windows 11 ARM on Parallels is usually tied to input polling and VM resource settings -- disabling heavy background apps, turning off key repeat delays, and making sure Parallels Tools is fully updated can help reduce it. Low-latency input is especially important for fast reactions in games where precision weapons like the AWP matter most: https://cs2.ad/rifles/awp
