We fired up OBS 23.2.1 and streamed our Twitch channel at 1080P 60FPS with the software X264 option at 6000 Kbps. This put an additional strain on the system drops the average frame rate by roughly 15-20% on most of the processors we tested.

We wanted to put even more stress on the system, so in addition to streaming to Twitch we also recorded the gamplay to the system as an MKV file using the Indistinguishable Preset and the x264 software encoder once again.
