I have 2 Nvidia GTX 780's in SLI, and I tried the new Shadowplay recording and it worked fantastic for one week! I was capturing at 1920x1080 at 60 FPS and was getting no frame skips. After reducing it to 1280x720 at 30 FPS with frame smoothing in Premiere, it looked absolutely amazing. Then, one week after I bought the cards, Nvidia released a driver update (GeForce Experience 1.8.0.0), and it hasn't worked since. Capturing at 1920x1080 now only captures a squashed picture at 1920x540 in size. It's only capturing every 2nd scan line. I've tried everything I can think of to fix it, without any luck. (Changed number of screens, tried with and without SLI, etc) If NVidia ever fixes this problem, Shadowplay is definitely the best method of capturing. You can have it on all the time, and there is no performance hit. By having it on all the time, you can select when you want to just save out the last 10 minutes of footage, if "something wonderful" occurs during game play that you think is just an awesome "must show to the world" type of event.
