Anyone with a 600 or 700 series card try this yet?

Im gonna have to grab this and post some videos of how terrible I am.

JR was showing me at the lan. I have dual 680 cards, I myself have not tried it yet. But it is a interesting concept.
-
Too bad this doesn't work with the 500 series cards. I would love to have the constant ability to record any moment in gaming.
-
I'm in the same boat of having 500 series cards installed.
Right now I am using Open Broadcaster Software, that is an open-source free program that will stream or record (or do both simultaneously) any game footage or even just what is happening on your desktop.

It's a pretty intuitive program to use. I don't stream with it, but I do record. It's different from shadow play in that you need to do (what appears to be) a bit more set-up. But I find it's nice, and I can go back and make edits with my editor of choice.

Do you have any examples of recordings from OBS? I'm looking for something to replace FRAPS. The file sizes are out of control. I've tried dxtory but Adobe Premiere doesnt seem to like how the video is encodes. I also cant do 1080p recordings due to too much load on the cpu.
Shadowplay seemed like a good ideas as I need to upgrade from the 570 I have now. The 600/700 series cards have on board h264 encoders so there shouldnt be a performance hit at all. I'm very curious about the quality of encodes and any available options for quality, resolution, etc...
Looking forward to hearing some details about both from you and Tibbs if you guys and provide some.

ShadowPlay is cool, if you use the Shadow option and have a smaller SSD as a boot drive, make sure you change your Temp path - it records your buffer there by default and then dumps it to your record path.
Only downside to Shadowplay is it doesn't record your local mic input. You could loop yourself back into the audio stream and mute the output (should still record on the audio track) but the fact it doesn't do that is pretty lame. FPS impact on my 770 was negligible, 5-10 FPS tops. Even OBS sucks down some CPU during encoding on the fly, nothing out there can really touch Shadowplay. I'd like to see some more encoding options (it's all h264, options are low, medium and high - that's it). Defaults to 1080p 60fps as well, which is fine, but it'd be great to have other options.
All in all, it's a cool feature, but needs some refinement before it's ready for primetime.

All of the videos on my gaming channel were recorded using OBS: http://www.youtube.com/MahoneyGames (http://www.youtube.com/MahoneyGames)
I have found the file sizes to be decent and not too large, even with an hour long recording session. I record first so I can get the highest quality, edit, and then post. If you want to stream you may notice some performance issues, and may need to downgrade the video quality. If you go with OBS, PM me and I will list the settings I use.
Bear in mind, these videos are recorded, compressed with the rendering, and then compressed again to fit YT standards. But they still can be displayed in HD.
-
Dude do you have any examples of quality? How does one loop their mic back into the sound stream?
Mahoney your videos look great. Youtube has for some reason been screwing me on quality. If you look at this video:
Some shens from FITES Summer LAN 2013 (http://www.youtube.com/watch?v=L8xgbhVeGKA#)
the quality is terrible. It does not match the original file quality at all. It must be due to the encoding process. What are you using for editing? Or are you uploading the direct output of the recording?
I'm worried about OBS as you mentioned its doing encoding on the fly and no doubt thats taking place on the CPU. As I mentioned I cant record @ 1080 with dxtory because its doing the h264 encoding on the cpu as well. I run into 100% cpu usage when recording at 1080p. Whereas shadowplay will utilize an onboard encoder on the 600/700 series cards.

I've had good luck with the below settings. It's pretty much just the Youtube 1080p preset in Premier Pro CC with the addition of the "Use Maximum Render Quality" checkbox.

Pretty much what Chr0n0 said. It's more about your post render than the recording session render. I find that if I render through premiere to h.264 (which is the YT preset) I get the best results.
I haven't checked my CPU usage while recording. I should since it would be interesting to see, but I haven't noticed any changes in my performance that make any game unplayable, or substandard quality. As a disclaimer, I am also not a frame-rate princess that can detect a drop of 5 - 10 FPS with the naked eye.
OBS does record on the fly, but I wouldn't really say that it is "encoding" or "rendering" on the fly. It's recording raw visual data through a h.264 filter so to speak. I'm not savvy enough to speak entirely on this issue, but I've noticed no decline in rig performance while running OBS.

Its worth mentioning that when I say I hit 100% CPU usage while recording with dxtory i mean that I can see the dxtory process and the BF4 process using all the CPU. Its usually a 65/35 split. They're fighting for cpu resources while recording @ 1080. However if i back that down to 720p cpu usage spikes every so often but its not as bad.
