Jarred Walton [Tom's Hardware] compares FPS using both AMD & Nvidia graphics cards across 14 games in both Win10 & 11 using a ~3 year old PC. The result was basically a draw, so if Microsoft's looking for gamers to give Win11 a boost, they way they did Win10, it'll be the folks running one of the new Intel Alder Lake CPUs. That's because they'll need Win11 to fully support the new CPU's architecture.
