Hello! I am wondering how the different enum values in EnviromentalPhysicsThrottle behave.
Disabled and DefaultAuto are self explanatory. I am assuming Skip X means it skips X iterations of the full 240hz. I’m not 100% sure. Finally, what does Always mean? Does this mean the throttle is always at 100%? I’m not sure what this could be.
Throttling occurs when too much physics is happening; the simulation is slowed down to keep frame rates smooth.
EnviromentalPhysicsThrottle is probably used to observe and debug the behavior of the throttler by overriding how much throttling occurs.
| Value | Behavior |
|---|---|
| DefaultAuto | Throttling determined by magic. |
| Disabled | Never throttle. Physics always at 100%. FPS will suffer for large simulations. |
| Always | Always throttle. Physics always at 0%. No physics steps occur. Very fast. |
| Skip2 | Throttles to 50% normal speed. |
| Skip4 | Throttles to 25% normal speed. |
| Skip8 | Throttles to 12.5% normal speed. |
| Skip16 | Throttles to 6.25% normal speed. |
You can observe how each value behaves by showing the Physics stat panel with Ctrl+Shift+F4. The PhysicsReal field shows the percentage to which the physics is being throttled.
