7950X3D not working as expected...

[sblantipodi]

Hi,
Horizon is not recognized as a game by my 7950X3D since I can see that all the cores are running the game.

I need to manually set "this is a game" on the Xbox Game Bar...

I never experienced this problem before, why this happen with such a masterpiece?

some games are not recognised by game bar as a game so it needs this to be done until they update gamebar with what new games are out.

this is the answer you need update game bar regularly.

The alternative is to go into your bios, turn PBO on and reduce the clockspeeds slightly lower on ccd1 below ccd0 so it latches on the 3d cores without fail.

put it in the recycler , thats it...

EDIT: I correct my self
Nothing can be solved with the xbox game bar.
if I specify that Horizon is a game from the Xbox Game Bar the game runs on the 3D cores and the other cores are parked,
but every now and then I see that 3 or 4 cores of the CCD1 have a spike of 20 or 30% load and at that precise moment there's a crazy stutter.

If I don't do anything from the Xbox Game Bar the game runs on all cores, I won't have the benefit of the 3D cache
but there is absolutely no stutter and it is buttery smooth.

It seems that 3D cores creates more problems that what it fixes on this game, this is the first time I see a problem like this on the 7950X3D.
can it depends from the fact that the game requires more than 8 cores and when it runs on the other cores it creates this stutter?

there are specific moments where I can clearly see that the games runs on 10 or 11 cores even if I select that Horizon is a game on the Xbox Game Bar,
from time to time, the parked cores are unparked and the stutter occurs.

the only way to solve the problem is to disabled "this is a game from the xbox game bar" and use all the CPU.

I thought AMD had solved these problems by now, very bad...

Relying on Xbox Game Bar (which is in and of itself a bug ridden feature) is a bandaid to a problem AMD didn't manage to solve with Microsoft.

It's not an actual fix to the windows scheduler, and even then Intel still keeps having problems on their big.LITTLE architecture despite all the Windows 11 scheduler optimizations.

Though, everybody and their mother new that 2 CCD CPU variant with 3D V-Cache was a mistake to buy for Gaming in the first place.
For purely gaming workload you'd be far far better off with 7800X3D and for mixed workload, Intel is still the kind in productivity while being competitive in gaming (especially if you tune the absolute horrid power targets).

Ok It seems that the stuttering is generated by RTSS, if I close it, stuttering is gone.

[MancSoulja]

The game uses idle cores to compile shaders on the fly, so maybe that's why you're seeing all your cores active.

Either upgrade RTSS to 7.3.6 or do not force CPU thread affinity if you stay on 7.3.5. Both will solve the issue:
