Why does everyone not mention Plays.TV? It's better than OBS which uses AMD's VCE, while Plays actually uses AMD's low level API x.265 frame capturing
Why are you so obsessed with AMD VCE? The NVIDIA Codec is so much better. Why do you think shadow play gets so much praise. + being able to use it on OBS with the multi channel audio and actual settings rather than the ui nvidia experience gives you makes it literally the best option for no lag recording.
