What I use to capture is a graphics cards hardware solution. I'm not sure which graphics card you use, but if you use an Nvidea, I might have something amazing to tell you. And it's free! And it works wonderfully, I really am hooked on it. It's called shadowplay. It uses your graphics cards that has a special chip on it and takes the stress off of the cpu, so you still have butter smooth gameplay, no lag and optimal recording. You should check Nvidea's website. I use a GTX 780 ti sc, but as far as graphics cards go, that pretty much is top of the line. So I had no problem getting support on it, but you should check it out, and maybe consider the investment to a new graphics card that is supported by shadowplay. I hope it helps!
