I was using Action! on Win 7 but after upgrading to Win 10 it stopped working and after some looking around I found Loilo Game Recorder. It's actually free with no water marks or file size limits and it records tiny file sizes with almost no FPS loss. The only down side is it doesn't have a ton of options but you can still pick quality, fps recorded, audio and mic volume, and all the other basic things. I guess to make up for it being free they try to sell you their video editing software which screwed up my video when I tried the free trial . Anyway if you are looking for IMO the best recorder paid or free try Loilo.
BTW if someone at Loilo sees this and wants to pay me for advertising I will gladly accept lol
