SAM causing massive stutters

I’m using the latest AMD Preview Driver with AMD Fluid Motion Frames.
I’ve been waiting for that for a while now.
At first I was a bit disappointed that it introduced quite a bunch of stuttering.

But then I’ve seen this thread here.
So I tried disabling ReBar and SAM and it did in fact make it a bit better.
But not yet good enough for my taste.

Then I also disabled SMT (multithreading) since I read that this might cause problems with darktide.
Again, a bit better but not yet quite good enough.

So, I searched around a bit more and found this video:

At first I thought this is probably nonsense (and the difference definitely isn’t as big as the thumbnail claims).

You can skip most the video (it even says to activate SAM).
What is interesting is the registry stuff.
There is a download with a bunch of files.
Basically some registry changes and using a MSI tool to increased the priority of the GPU.
I don’t know if this tool works with a non-MSI mainboard.

But to my surprise this actually did something.
I can now play darktide completely smooth with Fluid Motion Frames.
And I just have 150-250 FPS most of the time. XD
Before using this setup with Fluid Motion Frames it was more like 80-120 FPS.

I have a spot in the hub where I usually test FPS.
On that spot it went up from pretty reliable solid 90 FPS to ~150 FPS.
