Should I use Async & Await, instead of Coroutines, in Unity?
In contrast to Evorlor's answer, here are some good reasons to use Coroutines:
They've been the standard solution in Unity for many years and anyone else you bring onto the team should already be ...

Would I need to develop a multi-threaded game or will a single thread suffice?
Generally it's best not to over-engineer, solving problems you may not really have.
If you want to make a "simple 2D fighter," well, remember we had those on the NES and even earlier.
Even a single ...

How Many Threads is 'Too Many'?
What matters is not the number of threads, but their CPU time
Probably you do not need your threads to have full utilization. If you do, get better hardware. In fact, you can use CPU utilization as ...

Multithreading MMO Server. A thread per area OK?
I think this might be a viable architecture. The biggest source of bugs in multithreaded applications is shared access to data. So when the rooms have little to no communication with each other and ...

Two Gameloops instead of one, wouldn't it be better?
That's an interesting idea, however...
With multi-threading, you lose your advantage because you have to stop the update thread when you update your graphics.
Think about it: if you render at the ...

Multithreading: Each system on a different thread or a thread pool?
One important concern when deciding units of parallelization is usually to avoid sharing data between threads. Multiple threads operating on the same data is always hairy, because:

How would you write a multithreaded gameloop in C++20 (+) or C++/WinRT?
When you are separating a game engine into threads, then there are two main concerns:
Each worker-thread should have roughly the same amount of work to do
Avoid communication and data sharing between ...

Can a loading screen be implemented using one thread only? If so, how?
You basically have to break down the loaded data into smaller chunks, and intersperse UI updates in between those bits of processing. The finer the granularity of the chunks of data you synchronously ...
