What's new in 1.131.0
[1.131.0] - 2026-10-26 GPU usage and video memory now work on Intel and AMD graphics, not just NVIDIA — the Dashboard and Resource History read the same counters Task Manager does. Added - GPU usage for every vendor. The Dashboard's GPU tile and the Resource History chart read load and video memory from the counters Windows publishes for all graphics hardware, the ones Task Manager's own GPU column draws. On a machine with more than one card, the busiest one is shown — on a laptop with switchable graphics that is whichever card the app in front of you actually landed on. The figure is each engine type's share added up and then the busiest engine type, which is how Task Manager arrives at its number too, so the two agree. Fixed - GPU usage read 0% on every Intel and AMD GPU. Usage and video memory came only from NVIDIA's own API, so on any other card the Dashboard showed "GPU 0%" with an empty bar — a number that reads as an idle GPU, on most of the laptops this app is aimed at. The card's name was shown and nothing else was wrong, which made it look like a measurement rather than a gap. - A GPU that cannot be measured now says "N/A" instead of 0%. "Nothing can read this" and "this GPU is idle" are different answers, and 0% is a legible number that means the second one. A machine with no usable GPU counters — no WDDM 2.x driver, or one between driver states — now says so. Changed - The GPU temperature still comes from NVIDIA cards only, unchanged, and it is still the only GPU temperature readable without administrator rights. Giving it the same vendor-neutral treatment needs a different Windows interface and is a separate change.
