High polling rate mice are causing performance issues (windows, editor)

May 25, 2022

Reproduction steps:
1. Open users attached project (note this project doesn't use the new input system, but the issue manifests in the new input system too. See ISX-1506)
2. Press the "Stats" button on the Game View window
3. Enter the Play Mode
4. Move the mouse rapidly over the Editor
5. Observe the Frame rate in the Stats window

Expected result: Frame rate is stable
Actual result: Frame rate is jumping from ~400 to ~200

Reproducible with: 2019.4.38f1, 2020.3.33f1, 2021.3.0f1, 2022.1.0b16, 2022.2.0a11

Notes:
-reproduced with Razer Viper
-frame rate drop is more apparent with a higher polling rate (1000hz)
-in 2019.4, the performance drop is not as major, but still visible
-reproduces in any project

Resolution Note:

There are no fixes planned for this Bug

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

Can also confirm for 2021.3.5f1 with Logitech G502 at 1000Hz. Build is running smoothly if mouse is stationary, but any rapid movement causes lagspikes in the "Others" section of profiler. In Editor, it goes to EditorLoop.
