Thie HD60 S+improves upon a number of areas:
* UVC Support - USB video support means that no software/drivers are necessary. When it's connected, your computer will treat it the same way it would a webcam
* 4K 30FPS Recording - Most gamers will still record and stream at 1080p, but the addition of 4K at 30FPS is a welcome one.
* 4K 60 FPS - You can now play games at 4K 60 FPS on your television and record at 1080p 60 FPS
* HDR 10 - HDR 10 is supported when recording at 1080p
If you're looking to buy a new game recording device, this should be at the top of your list (unless your budget is significantly higher and can afford to buy more professional gear from companies such as Magewell).
