High polling rate mouse causes performance issues
Reproduction steps:
1. Open new Unity Project
2. Enter Play Mode
3. In Game View, rapidly move mouse around, with its polling set to 1000
4. In Profiler window, Editor mode, observe performance
Expected result: Performance does not slow down
Actual result: Editor performance slows down significantly
Reproducible with: Razer Viper Ultimate
Not reproducible with: Steel Series Rival 600, Steel Series Rival 110, Logitech G903, Razer Naga Chroma
Affected Unity versions: 2018.4.35f1, 2019.4.28f1, 2020.3.11f1, 2021.1.11f1
Notes:
1. The issue is much lesser when outside of Play Mode or when moving the mouse around in a Build
2. The slowdown seems to be correlated to the polling rate of the mouse. Setting it to 100 nearly negates the issue.

This issue is still present in Unity 2022.3.45f1 while using the Razer DeathAdder V3.
Setting Polling Rate to 500 fixes the issue. -

Another vote for fixing this in 2020 LTS. It's impossible for us to upgrade major versions with how the engine has been "progression". High refresh mice are becoming more common so more players are having issues. No way to vote for an issue when it's "fixed" but only for some of the affected versions isn't great either.

Still present with 2021.3.8f1 LTS. Almost unusable at 1000 Hz. It's better with 125 Hz but it still have mini lag spikes every now and then. This issue should be a priority to fix on LTS versions. It really impacts the work.
Reproducible with: Corsair Harpoon mouse -

This issue is not fixed on 2021.3.5f1
It can be seen both in Editor mode, gameplay mode and when playing a build.
Mouse polling rate at 500hz or more severely impact framerate.
At 125Hz the issue is much less noticeable but do not completely disappear. -

Hello, any update on the LONGTERM SUPPORT version fo 2020? It's not very usable with this bug present in my opinion.

Is there a plan to fix this in the LTS version of 2020?
