Issue description
Resource (re)importing speed is affected by editor framerate, leading to slow import speeds when the window is unfocused. This is particularly the case when importing lots of small resources that import fast individually (as opposed to few large, complex resources). I noticed this while testing #93727.
This is a frequent problem in various games and apps, to the point where many games disable V-Sync and any built-in FPS limiters during loading screens to speed them up. We can likely do something similar here.
Project exporting may be affected by similar issues as well, but I haven't tested.
Time includes editor startup + shutdown time. Tests done on a 120 Hz display.
| Mode | Time taken |
|---|---|
| Unfocused (10 FPS1) | 12m05s |
| Default (120 FPS) | 1m09s |
| Update Continuously (120 FPS) | 1m09s |
| No V-Sync (145 FPS) | 1m08s |
| No V-Sync, Update Continuously2 | 23s |
Command used for testing
Steps to reproduce
- Open the MRP and measure the time taken to import all resources (e.g. using the command line or with a stopwatch).
- Set V-Sync Mode to Disabled and enable Update Continuously in the Editor Settings.
- Exit the editor and remove
.godot/in the project folder. - Reopen the editor on the project and measure the time taken again.
- Your mileage may vary if your OS/graphics driver forces V-Sync on all applications.
