To record in MSI Afterburner (see image at the link). In the graph, right click and select "properties". Then on the "Monitoring" tab you can enter "hardware polling period" (I use 100ms). Also set the file path (add .csv as the file extension to open with excel or open office). Also select what parameters you wish to log. https://cdn.videocardz.com/1/2017/10/RX-Vega-Afterburner-OC.jpg Then when you want to log to file just right click in the graph area and select "Log History To File". Afterwards, stop logging and you can view the data in Excel. From the graphs you have shown both the CPU and GPU are showing less than 100% but your fps is still up and down. With neither maxed out it should be steady at whatever frame rate you set in the player.json file. Either that or because of the polling period of the hardware the graphs are not showing the whole story. Or possibly a result of using Steam VR which is why I binned in for OpenComposite.
