Affinity inheritance not working

I'm not seeing games launched via Steam inherit affinity settings for steam.exe. I'm on a 9950x3d with the latest AMD chipset drivers. Core parking works via the game bar/drivers, but I'm trying to use Process Lasso for a bit more control. To prevent core parking while testing Process Lasso, I set the power plan to performance.

Can someone confirm that affinity inheritance with Steam is working on the latest version of Process Lasso and Windows 11?

Thanks!

Update: I had a friend install Process Lasso, set steam.exe affinities to cores 0-5, and he also didn't see it get inherited by the game process. Is this to be expected? I'm trying to figure out how to apply affinities to processes that are protected by anti-cheat (I read that applying affinities to the launch such as steam.exe is the solution).

To our knowledge, affinity inheritance is working correctly.

What game(s) have you tested on? Some games may set their own affinities and override the inherited setting.
