Xsplit is good and has all you need when just streaming vidya, try it out while you can, its gonna become non-free pretty soon (and will be quite expensive).
I grabbed the beta to give it a whirl, but it doesn't support DX or OGL capture without a license. Don't fancy running my games in windows just to stream. unless I'm missing something?
Seems to be the unfortunate sideeffect. For LoL and HoN I couldnt find any other solution to this other than running it in windowmode with
Shiftwindow unfortunately. The new Gamecapture method seems to solve that but thats prepurchase only as of now.
