I'm running Handbrake and it maxes out all 4 cores of my I5. Do programs still have to be written specifically  to take advantage of several cores, or is windows [10] getting some smarts and load balancing the work also?

There are ways to implement it in code, but most often this happens as demonstrated by these lovely puppies.

It needs to be programmed in.

Depending on the language sometimes things can be run on multiple threads even if the program isn't coded for it, for example garbage collection and stuff, but that won't use a core anywhere near 100%.

Great!

I guess the programmers at Handbrake know what they are doing. My cores all get maxed anytime I encode something. They utilize it all.

That's how almost all rendering programs work.

It's easy to split up rendering workloads over multiple threads.

handbrake is just a gui, its all ffmpeg under the hood.

 

and It doesn't max out my 40 thread system, so not perfect, x264 doesn't so well with tons of threads.

I'll have to see how Handbrake behaves on my I7.
