Help Poor performance due to semaphore wait for signal

[Henning]

Hi,

There's no image attached to your post. Either paste a link to it, or attach the file to the post (make sure you press "AddAttachment" after dragging the file!).




Not at all, "wait for signal" just means the main thread is waiting for something. Could be rendering, could be physics, AI, input, literally anything, depends on the context. If it's happening in FixedUpdate(), a safe guess would be it's waiting for other threads that are performing physics simulation.

Check other threads in the profiler, see if they're doing any work while the main thread waits. If they are, it means the main thread is waiting for them to finish so your focus should be on optimizing whatever those other threads are doing.

kine regards,
