Reproduction steps:
1. Open the attached "PROJECTFILE" project
2. Build And Run the project (File > Build And Run)
3. Observe the frames per second “FPS:” value visible in the top left corner in the Player before doing any changes
4. Press the “SPACEBAR” keyboard key 2 times to change the “V-sync: 0” value to “V-sync: 1” and then back to “V-sync: 0”
5. Observe the frames per second “FPS:” value

Expected result: Frames per second “FPS:” value goes back to how it was before the “V-sync” changes
Actual result: Frames per second “FPS:” value drops by ~15% and is lower compared to how it was before the “V-sync” changes
