Regression

No

Frame rate stutters in macOS Player when vSyncCount is 2 or more

-

Reproduction steps:
1. Open “vSyncCountProject“
2. Open “SampleScene“
3. Build And Run
4. Observe frame rate stats for 30 seconds

Expected result: frame rate does not stutter, and the average frame rate is half of the screen’s refresh rate
Actual result: occasionally frame times slightly decrease or double, and the average frame rate is below expected by one or more

Reproduced in: 2020.3.46f1, 2021.3.20f1, 2022.2.10f1, 2023.1.0b7, 2023.2.0a5

Reproduced using: macOS 13.0.1 (Intel)
Not reproduced using: Windows 11

Notes:
1. The user reports consistent 120 FPS when vSyncCount is 1 but 57-58 FPS (without reaching 60) when vSyncCount is 2
2. Unable to test in Play mode because vSyncCount has no effect in Play mode

    That's not cool.
    I would fix that myself but generating Xcode project source for Mac OS platform doesn't work for some reason.
