// This component is a workaround for issue https://github.com/XLabsProject/iw4x-client/issues/80
|
|
// In case the link goes down, this is a "game hangs randomly" issue:
|
|
//
|
|
// Investigations on the issue pointed out it comes from a situation on Intel processors where
|
|
// WaitForSingleObjectA is ignored by a thread, for some (?) reason.
|
|
//
|
|
// This locks up the game randomly, mostly at the end of rounds or when too many things happen at
|
|
// once, due to trying to stop sounds (AIL_Stop_sounds) and playing streams at the same time,
|
|
// rushing for the same resource via AIL_lock_mutex.
|
|
//
|
|
// This bug has been reproduced on mp_terminal, mp_overgrown, mp_rust, with and without bots,
|
|
// and so far this has been the only way to circumvent it afaik. This component wraps
|
|
// miles' mutex into another mutex, created below, and for some reason (?) that mutex is
|
|
// respected when miles' is not.
|
|
//
|
|
// As soon as a real fix is found, please discard this fix. In the meantime, it should not
|
|
// have side effects too bad - worst case it might cause a slight performance drop during
|
|
// team switch and intermission.
