I use the cpu sets feature. Have your applications running and then you can just select each one in the lasso menu and assign the program to a cpu set or to a cpu affinity. I use sets which is a softer way to do it but the instruction manual for lasso is excellent and explains it well. I don’t use most of the lasso features as it’s quite powerful but for basic setup it’s not hard, just read over the manual and it’s fairly intuitive. Search for it on this forum and you will find various posts about it too. I would not bother with a lot of the features, you simply want to assign MSFS to 3d vcache cores 0-7 and the rest of your programs to 8-15 if you have a 16 core AMD chip. Don’t touch the windows background tasks, just the programs you are running should be assigned. It’s possible to move the windows background tasks as well but I don’t mess with those. You can also easily toggle lasso on or off once it’s set up too see how it impacts your setup, for some it helps out with MSFS frame timing/fps and for others it doesn’t, it’s very dependent on your setup/applications running.etc.
