I have been using virtu mvp and here's what I found. I have a 3570k/7870 by the way. In games where I need to use an fps limiter( skyrim, metro 2033, etc.) it will make the game smooth without the fps limiter. In most games though it either won't launch at all or will feel like I'm getting 25 fps when fraps counts 130. I have uninstalled it.
