How does conditional variable Wait work?
Condition variables: used to wait for a particular condition to become true (e.g. characters in buffer). wait(condition, lock): release lock, put thread to sleep until condition is signaled; when thread wakes up again, re-acquire lock before returning.
What is conditional wait?
What are conditional wait and signal in multi-threading? Explanation: When you want to sleep a thread, condition variable can be used. In C under Linux, there is a function pthread_cond_wait() to wait or sleep. On the other hand, there is a function pthread_cond_signal() to wake up sleeping or waiting thread.
Does Lock_guard wait?
Use lock_guard unless you need to be able to manually unlock the mutex in between without destroying the lock . In particular, condition_variable unlocks its mutex when going to sleep upon calls to wait . That is why a lock_guard is not sufficient here.
Does Pthread_cond_signal unlock mutex?
The pthread_cond_signal() routine is used to signal (or wake up) another thread which is waiting on the condition variable. It should be called after mutex is locked, and must unlock mutex in order for pthread_cond_wait() routine to complete.
Does lock_guard block?
The class lock_guard is a mutex wrapper that provides a convenient RAII-style mechanism for owning a mutex for the duration of a scoped block.
What is the difference between unique_lock and lock_guard?
A lock_guard always holds a lock from its construction to its destruction. A unique_lock can be created without immediately locking, can unlock at any point in its existence, and can transfer ownership of the lock from one instance to another.
Is it good or bad to use triple buffering?
The only reason it might different from what the game gives you, is many games do not use triple buffering. Triple buffering has both good and bad attributes. The good is that it allows frames to be generated while waiting to display your current frame, so you don’t lose FPS with V-sync on, while below your refresh rate.
Is it worth using VSync with triple buffering?
Yes, but idk why you’d wanna use vsync in all your games as it causes a lot of input lag, especially with triple buffering. “A lot” is dependent on the game. Some games aren’t too noticeable, IMO, making V-Sync worth using. Honestly, I can barely tell a difference. You should triple buffer any game as long as you have the VRAM.
What are the options for triple buffering in Nvidia?
That’s why there’s two options for Triple Buffering: Double Buffer (Front Buffer + Back Buffer) Triple Buffer (2 Back Buffer + Front Buffer) Triple buffering, I want to know more.
Can you force triple buffering in DX games?
You need a third party program like D3DOverrider to force triple buffering in DX games and it’s a God sent. For those who don’t know double buffered VSync will either play at 60FPS or 30FPS as soon as you get below 60.
