Win11 any suggestions to speed it up

[yutasakana5]

Hello to everyone. I am an interior architect and I use 3ds max, substance painter, photoshop etc. the thing is before upgrading to win 11 from win10 I run mu softwares more smoothly even file explorer. For instance 3 windows of 3ds max open 1 was rendering and I make small alterations in other 2 3ds max simultaneously. And at the same time lots of chrome tabs used to be opened additionally photoshop and substance painter were open but minimized. And several file explorer windows. But with win11 I can’t use 2 3ds max simultaneously everything slows down and nothing run smoothly. Is there any tweak or any release to win11 or should I simply go back to win10 Iot ltsc. https://speedtest.vet/

You don't mention how much RAM you have, so there's that, nor how heavy these scenes are. Overall Win 11 has been both stable and fast with most versions of Max for me, though I admit to never having three instances open at once. Either way, below are some suggestions:

If you really need all three open plus Photoshop I'd say 64GB of RAM would be where you'll want to be. 

In Photoshop: reduce how much RAM it's using and reduce the GPU memory it can utilize.
All browsers like to hog up GPU memory as well, so set unused tabs to sleep as soon as possible.

I'm just guessing here, but turn off anything game related in Win11, especially relating to graphics and full-screen game play. Microsoft put extra effort into making Win 11 more "games friendly" and there are graphics settings where everything else gets bumped down in priority when a full-screen game is being played. 

By default, I believe the above setting is ON. Thus Max could look like a game in terms of resources except then all three would be trying be the "one." So in that case, keep all instances floating, or minimize Max windows that you're not actually focused on.

The thing to remember here is that most apps want to be "speedy" and thus will happily grab everything they can to do so. You have to force them to play well together.
