Irrlicht Engine

My project is a screensaver and I need a good method for retrieving if a certain amount of time has passed, windows requires this for the screensaver to close. I'm sure this community already has one so I'd save some time by asking the simplest efficient way of doing this.

Irrlicht's device has a timer built into it. just do . It keeps track of how many milliseconds have passed since the program opened, and can be stopped and started.

On Windows you probably need to enable the high-resolution timer.

I myself always use native c++ "chrono" namespace timers. There are several types of them so I think you should find what you're looking among them.

Just google "c++ chrono"

there's the window performance counter functions

all that high precision and perf counters are overkill, seriously. irrlicht uses GetTickCount() under the hood when not using high performance timer. GetTickCount() has 15ms resolution. That is plenty for just about anything.

You only have to *enable* the high-performance timer and GetTickCount will have millisecond accuracy. You don't have to *use* the HP timer.
