3. Enter Play mode and open the Profiler window (Window > Analysis > Profiler)
4. Observe the “SetMotorSpeeds” frame in the Timeline section of the Profiler window

Actual result: CPU usage for “SetMotorSpeeds” frame is 0.970-1.50ms
Reproducible with: 1.7.0 (2023.2.9f1), 1.8.0-pre.2 (2021.3.35f1, 2022.3.19f1, 2023.2.9f1, 2023.3.0b6)
Reproduced on: Windows 11 Pro, Windows 10 (By reporter)
Not reproduced on: No other environment tested
Note:
- Couldn’t test on DualShock and DualSense as controllers didn’t rumble or rumbled inconsistently
- User reported that the issue is also reproducible in the Player

A Correction,
We did some tests and it appears to be an issue with Xbox controllers (both Xbox One + Xbox Series controllers). We didn't see the same values for PS4, PS5 or Nintendo Switch Pro Controllers -

Just experienced this issue yesterday. Present in 1.7. Basically a blocker for using the Input System/Rumble with a controller in a shippable PC build as most users will have Xbox gamepad. The workaround is to use less rumble for now, but really not ideal... Please fix this.
