Heya,
here is a small tool which basically on the fly "converts" (very easy put) every video to 60fps. And as we all know 60fps > rest specially for PV/Concerts etc.

And here a really good player which will strain your PC less while doing this.

Of course it all needs like 5mins setting up but it is so worth it.
I5 2500k 4ghz
EVGA Gforce 770
8gb RAM
And my CPU load with it on is around 40-50% when you take the time to set it all up. If not than its around 95-99% .
