Anyway, ShadowPlay is brainless to set up (because it's already done). A key command will automatically save 5 minutes of past gameplay. The high setting will make a 1.9GB file in that 5 minutes (resolution is 1920x1080 at 60FPS). I don't know if the driver scans your system and gives you the best setting for your rig, but that was automatically selected for me. You can also extend the automatic shadowplay mode for up to 20 minutes (7.5 GB file) and lower the quality. Finally, you can also go into 'manual' mode, which I'm guessing is recording whenever for however long that you want to.
