RESOLUTION
How many pixels are drawn. 100% is your screen's own; lower is faster and softer.
ANTI-ALIASING
Smooths jagged edges by drawing each pixel several times; more is smoother and costs more.
EXPERIMENTAL
AMD FSR 1
FSR MODE
AMD's FidelityFX Super Resolution upscaler: the frame is drawn smaller (by the mode, or at the resolution above in Custom) and upscaled edge-aware to the target (100% is your screen's own pixels; above that it is shrunk back down, smoother and dearer), then sharpened. The mode sets how much smaller the frame is drawn: Ultra Quality is sharpest, Performance is fastest.
FRAME GEN
MULTIPLIER
Generated frames are the last drawn one, moved to where the camera is now. Hands are drawn fresh; moving things hold still until the next drawn frame.
The play benchmark restarts the level and plays it nine times over, about seven and a half minutes: with the HUD, without it, flat and frozen, at each anti-aliasing setting and at half resolution. Then it says which settings suit this machine and saves the full log to the browser's downloads.
RECORD MY PLAY logs your own play the same way, from resuming until you next pause (ten minutes at most), and saves it.
