There are two incorrect things in the Delfy video that I spotted: r_lod 2 instead of r_rootlod 2 and the recommendation to use -threads -high in launch options (granted, I skimmed through it).
Anyways, the mastercomfig docs are open source! So you can improve them however you'd like.
AimIsADickThey're the same metric type, not actually the same metric. The difference between the two is in how the information is represented. Frametime represents the time it takes to render the frame, while frames per second represents the amount of frames generated in a second. What I'm saying is that frametimes are generally better than frames per second as a benchmark metric, because it gives more information.
How do you think a game engine or any benchmarking tool measures FPS? It uses frametime by measuring the time taken between the start and end of the frame, then takes the reciprocal of that (divides 1/frametime).

You may be thinking of dxlevel 98.
