Can't set Affinity on TR Pro 5995WX?

Hey all, (sorry if I’m posting in the wrong section)
I’m trying to validate Threadripper for our software. Our program is highly latency sensitive and we’ve had an easy time with consumer hardware. The issue is now with all these processor groups, bad scheduling and a program that was never really built for this many cores, I’m trying to test and find a temporary fix to resolve some of the issues with frame drops that we’re getting on TR systems. Eventually we will work out how to build our software for TR directly but for now…

The main issue I’m getting is TR is giving me an access is denied when trying to change the affinity of certain applications, ours included. Never had an issue with consumer CPUs, option is there and can be changed but TR? Nope. It’s not a permissions issue, been through that years and years ago. Even Process Lasso is saying “Hey, we can only try to force affinity on multi-group CPUs.” And according to the load distribution, it really can’t force it very well, or at least well enough to mitigate the performance hit of jumping CCDs.

I tried searching for hours, watching all the TR content over on L1 YouTube to try and see what I’m doing wrong here. Can’t force it with start args. What on earth am I doing wrong or missing? Thoughts?

Go in bios set nps4 and latency wjll improve for your app all else being equal

Wow, thanks Wendell! I’ll do some research on NPS4 and give that shot for sure!
