:title: async num threads

:location: :bdg-success:`Launcher > Settings > Gameplay`
|
|
|
|
Number of threads spawned for physics updates (processing actor movement) in the background.
|
|
A value of 0 means physics update runs in the main thread.
|
|
Values > 1 require Bullet physics library compiled with multithreading support.
|
|
If multithreading is unsupported, a warning is logged and value 1 is used instead.

:title: lineofsight keep inactive cache
|
|
:type: int
|
|
:range: ≥ -1
|
|
:default: 0
|
|
|
|
Duration (in frames) to keep line-of-sight request results cached.
|
|
Line of sight determines if two actors can see each other, used by AI and scripts.
|
|
0 means cache only for current frame (multiple requests in same frame hit cache).
|
|
Values > 0 keep cache warm for given frame count even without repeated requests.
|
|
If async num threads is 0, this setting is forced to 0.
|
|
If Bullet is compiled without multithreading support, uncached requests block async thread, hurting performance.
|
|
If Bullet has multithreading, requests are non-blocking, so setting this to 0 is preferable.
