I bought this Surface Go 2 in 2020 knowing it was not a very powerful machine, but it was OK. Nowadays it’s *completely* unusable with Win 11. But… Fedora has breathed new life into it, and the kid can now have a light gaming laptop with Steam, Roblox, and DOSBox! It’s good.

The "2 Billion FPS" Method (The Repetitive Trick) At 2 billion fps, you are not filming a single pulse of light in one go (like a normal video). No commercial camera sensor can read data that fast for a full image. How it works: This method uses a technique called stroboscopic or equivalent-time sampling. You fire a laser pulse thousands of times. The camera captures only one tiny pixel or a small slice of data per pulse, with a very precise timing delay (e.g., delaying the capture by 0.5 nanoseconds each time). After recording thousands of pulses, you stitch these tiny slices together to form a "video" that looks like a single pulse moving. The Result: You see a pulse of laser light traveling across the screen. At 2 billion fps, the light moves about 15 cm (6 inches) per frame. This makes the movement look slightly "choppy" or stepped, rather than perfectly fluid, but it is distinctly visible.
