I think the 'Dedicated' one is equivalent to Afterburner's default VRAM readout in Hwinfo, which just tracks how much of the card's VRAM is being used total, including what Windows and any other programs are using. Afterburner also has one called 'Memory Usage \ Process' that tracks the VRAM of the overlaid process only, which can be helpful for knowing exactly how much memory a game is using without Windows or anything else skewing the result.Also, which VRAM sensor should I be paying attention to the most?
