If you want good quality game play you are down to 2 choices DXtory and FRAPS. Both have advantages and disadvantages. For 70% of my recordings i use DXtory because it allows you to play normal FPS and record at 30FPS or 60 which ever you choose. With FRAPS you are forced to play at the FPS that is recording, so if i want to record a game at 60FPS then im forced to play at 60FPS even if my card can do 200FPS. My computer is not even impacted by performance drop with Dxtory, slight frame drops with FRAPS. But for me when i record BF4 with Dxtory it always comes out really choppy and non fluent. Because of this, for bf4 only i record with FRAPS. Everything else i use DXtory.
