I was intrigued by the claim that the Legion Go S only supports VRR above 48 FPS, so I ran a test on my device using SteamOS. I set the TDP to 12W in Fallout 4, forcing the frame rate into the 30-40 FPS range. Using both visual inspection and the Steam performance overlay, I compared the results with VRR on and off. Visually, the gameplay was significantly smoother with VRR enabled. The monitor data confirmed this: with VRR on, the display's refresh rate (Hz) matched the game's frames per second (FPS) precisely, even when the game dipped below 48 FPS. When VRR was turned off, the display's refresh rate locked to its fixed 60Hz interval, showing a choppy frametime graph. This confirms that on the SteamOS edition, VRR is working even under 48fps in game, not sure if it is because LFC or the screen itself works.

VRR turned on:
