2019 LTSC vs 2021 LTSC

[Lewis777]

Hello. In the previous topics, I said that I installed 21H2 LTSC on my new computer, but then it started to use a lot of ram, it uses 8 GB of RAM when idle, it spends 4 GB. And the CPU and disk usage is too much. Therefore, I think I should install 2019 LTSC for less ram consumption and better performance, how is the 2019 LTSC. My system specs are Asus x515EP i5 1135G7 MX330 8 GB RAM 512 GB SSD.

I still run LTSC 2019 (1809) on my X58 system but I wouldn't recommend installing that version anymore. Many newer games and some programs require newer version of Windows 10, usually 1909 or 2004.

21H2 on my main system has a weird commit issue I didnt have in 2019, basically the commit is around double of physical ram usage which is odd, I observed its GPU accelerated software that makes this worse so e.g. if I play a game that uses 10 gig of ram, it will use 20 gig of commit (virtual memory). To compensate I have set a very large page file configuration so I have high commit capacity, the good news is mapping commit to page file actually doesnt cause page file i/o, it just needs to be backed not utilised.

Deffo install 21H2, 2019 is lacking a fair few things, notably the most modern gaming features like variable rate shaders, and directstorage. Also missing things like HAGS and WPA3 support.

Get more RAM.

I've used 1809 LTSC for a long time and it was flawless. But because of gaming I had to move up, so RN at 21H2 LTSC. The 1809 was a much better overall experience.

I have to completely disable the page file to make it work properly. It's preventing me from shutdown/reboot.

So, if a person was putting it on a server, as a game server, would it matter which one a person used?

I could upgrade to 64/128 gigs but it would be just for the purpose of satisfying committed but not utilised memory. Using a page file to satisfy commit has no performance hit.

Plus I dont think this is normal behaviour, this weird behaviour only happens on my main rig. There is a pool management tool someone talked about on TPU a while back which I bookmarked, whenever I get round to it I plan to diagnose it a bit more.

Ultimately I suspect the solution will be a clean install of windows.

I should have quoted OP, was referring to his problem in my "get more RAM" post.

well, you can check whether games or programs you use do req newer than 1809 instead of blindly using newer win 10 builds which are slower, especially on lower end hw. and why one would "upgrade" hw when there is no real need besides stupid ms that makes every newer win 10 (and now 11) build using more resources?

thank you for this reminder, now i have a REAL reason to use 21h2 vs 1809.
