Printing to the console, why so expensive? Curious.

Because, when you disable IO buffering, it has to push every single character through all the OS' rusty pipes.

Expensive compared to what?

S0ll0s: Right, since no memory is available.

Undef: Functions in general, math.random() kinda

is that supposed to be sarcasm? Unbuffered IO is generally expensive.

Naw, no no. I didn't understand buffering had to do with memory. No memory = printing every single character then next and so on...

Out of curiosity... why is unbuffered io used? Is it so that if love crashes the console will still have all output? Or is it something else?

Printing is mainly used for debugging purposes, so you usually wouldn't print out hundreds of lines of code per frame.
Therefore it isn't regarded as an efficiency impairment for game development.

Ahh that makes sense.

Plus not having console debug output during tests running sucks a lot.
