That's what I use
After you watch a movie with SVP (Smooth Video Project). nothing looks good anymore except SVP
I've been trying it out since it was mentioned here. I'd not heard of it previously. I must say that after the initial few uses i have warmed to the HFR effect. It takes some getting used to though. Ultimately i'm going to uninstall it as i can't tolerate the artifacts.
As a proof of concept i think it works tremendously. Perhaps Cameron and Jackson are right that HFR is the way forward. It would be nice if sometime in the future all video is shot at higher frame rates than those we are accustomed to!
Edit: Setting Artifacts Masking to strongest has eliminated all artifacts for me. I just watched The Avengers and it was incredible. I'm completely blown away, to the point where already I would hate to watch anything at low framerate again.
As far as resources during 1080 playback, my 3770k is at around 40% with all cores used and around 25% of my GTX570 being used.
Overall the SVP package is great. Picture and sound quality are far superior to the MPC-HC install that I was using before. I will definitely be sticking with it.
