Has anyone done a comprehensive comparison of Windows 10 LTSB/LTSC performance versus the mainstream Windows 10/11 builds on modern hardware (post-2020), specifically in areas like gaming, latency-sensitive workloads, or resource utilization on high-end CPUs and GPUs?

Most benchmarks and discussions stem from the initial LTSB/LTSC 1607/1809 releases and early consumer builds, but little is available regarding how the stripped-back nature of LTSB/LTSC affects real-world performance on newer silicon-especially given recent scheduler, security, and driver framework changes.

Is there evidence that LTSB/LTSC’s minimized telemetry, update, and UWP app overhead translate to measurable performance gains or improved system stability now that mainline Windows has matured, or are the differences negligible in modern environments? Furthermore, have any compatibility or optimization issues arisen with the latest graphics drivers, DirectX releases, or software (such as Adobe Creative Suite, professional DAWs, or recent AAA games) on LTSC, considering its slower update cadence?

Looking for data-driven input or field experience rather than general commentary on licensing or use-case policy.

One thing that often gets glossed over is how much driver and software support has started to hinge on being on a current Windows feature update. On my system (RTX 40-series, 13th-gen Intel), driver packages from both NVIDIA and Intel are now pretty blunt that support for LTSC 1809/1607 is sketchy at best-sometimes the installer blocks outright, or you miss out on control panel features. I’ve also run into issues with apps like DaVinci Resolve and new versions of Creative Cloud that expect underlying APIs and security features only present in 21H2+ or Windows 11. The minimized overhead of LTSC is real, especially on clean installs-boot and idle RAM/CPU are a bit lower-but honestly, on high-end recent hardware the performance advantage is negligible, and you can hit real compatibility walls if you need the latest drivers and software.

For stuff like ultra-low latency gaming or professional audio, mainline Windows (tuned and debloated) seems to match LTSC now. The bigger gain is just not dealing with bloat or random store apps, but that can be handled with careful setup on Pro. For lab or kiosk use, LTSC makes sense, but for daily high-end work or gaming with current hardware, the pain of fighting software/driver support probably cancels out any theoretical gain. Would be interested if anyone with more recent RTX/Arc/AMD setups has a different experience, though!

Something else to keep in mind: DirectStorage and some new GPU scheduling features flat-out require the latest Windows versions, so if you’re dabbling with recent NVMe drives or leveraging things like RTX IO, LTSC just isn’t an option. Also, a handful of new anti-cheat systems used by popular games (e.g., Valorant’s Vanguard) sometimes refuse to run or throw up warning messages on LTSC. It’s weird how quickly “compatibility” issues have gone from rare to routine in the last few years-feels like the software world left 1809 and friends behind way faster than anyone expected.

Another factor worth noting is that Microsoft has completely shifted its support resources and bug fixes to the mainstream Windows channel. I’ve occasionally seen critical hardware or security fixes for newer CPUs or chipsets land first-and sometimes only-in recent mainline builds. LTSC’s stability comes at the price of lagging behind in optimizations for cutting-edge hardware, which can actually mean less stability or feature support if you’re running a 12th/13th/14th gen platform or the latest GPUs. If staying current with hardware features and ensuring smooth updates is a priority, the mainstream branch really is hard to beat now.
