Microsoft VP fires back at Windows 11's new speed trick critics: "Apple does this and you love it." Windows 11’s hidden Low Latency Profile is getting dragged online, but the criticism misses the point. Windows Latest has tested the Low Latency Profile, and it truly works. When you open the Start menu, a menu, or an app, Windows briefly boosts the CPU for 1–3 seconds so the task finishes faster. On budget PCs, that can make the whole OS feel much snappier. Some users called it a “band-aid,” but Microsoft's Scott Hanselman pushed back and explained that macOS and Linux already do similar things. Modern systems boost CPU speed for interactive tasks because responsiveness matters. "Let Windows cook," Microsoft's legendary dev Scott Hanselman argues in defense of Windows 11's upcoming feature. Of course, Windows 11 needs to be optimized at the code level, but the answer is not “don’t boost the CPU.” Microsoft needs to do the best of both worlds. That means it needs to optimize the code, reduce bloat, and use modern scheduling tricks to make Windows feel fast again.
Microsoft's hidden Windows 11 trick makes apps launch 70% faster. I tested it on a low-end PC, and early results are promising. Right now, when you click Start, open File Explorer, launch Edge, or right-click for a context menu, and there’s often that tiny micro-stutter before anything happens. Microsoft is now testing a feature called Low Latency Profile. Once turned on, and you do a high-priority action, Windows 11 briefly pushes the CPU to max frequency for 1–3 seconds, finishes the task faster, then drops back down. In my testing on a constrained VM with just 2 cores and 4GB RAM, the difference was obvious. Edge, Outlook, Copilot, and the Start menu opened much faster. CPU usage spiked to around 96–97%, but only for a few seconds. For high-end PCs, the difference may be small. But for budget laptops and low-end Windows 11 machines, this could be a real game-changer.
We're rolling out a change in Experimental so file sizes in the File Explorer Details view now display using appropriate units (KB, MB, GB) instead of KB-only, to make them easier to understand at a glance Do you like it? 😊 learn.microsoft.com/windows-inside…
Microsoft is working on a special new performance boost feature for Windows 11 that sources say will speed up app launches by up to 40%. According to our sources, Microsoft is now testing a new "Low Latency Profile" feature for Windows 11 that will max out CPU frequency in short bursts whenever users open an app or system flyout. This is said to make the OS much snappier, with some apps seeing up to a 40% performance improvement at launch, and system flyouts up to 70%. More info at the link. windowscentral.com/microsoft/wind…
@mholt6 @WindowsCentral This mode temporarily boosts CPU clocks, in short bursts. Some users may not care about relative performance improvements and would rather maintain stable clocks. Also, it is not the most elegant solution. “Process too slow? Hmm, let’s throw more CPU at it instead of optimizing.”
TESTED: Windows 11's upcoming "Low Latency Profile" mode brings genuine performance improvements to the OS, speeding up flyout and app launches significantly. We've benchmarked opening some apps on video with the Low Latency Profile enabled and disabled, and you can see differences in how quickly things appear. For some things, it's a fraction of a second faster, for others, it's a significant increase in speed. In our testing, this new Low Latency Profile is a major improvement in overall responsiveness when it comes to opening apps and flyouts. Our tests were conducted on a clean install of the latest Windows 11 preview build on the same hardware. windowscentral.com/microsoft/wind…
