I tested this over the past two days and noticed that my inputs did feel faster but it negatively affected my hit registry.

Need more info from Foul Play as this may have potential. For now I reverted the changes

I have tested this on my system with different combinations of the 3 registries, as well as setting the values to 0 and ffffff. In my case, having only SecondLevelDataCache only and at 0 gave me the best input latency. Second best option was Second + Third both at 0.

Why don't you set the reg values to what the cache actually is?
L1 is 512 decimal
L2 is 4096 decimal
L3 is 98304 decimal

You're just messing up the values.

I don‘t understand why you want to change the registry at all. Were the values shown wrong in task manager?

Because windows isn't set up to make use of the excess L3 cache that the x3d chips utilize.

That is not true. Windows will recognize the extra L3 cache. Check your task manager. It clearly sees the extra cache.
Registry keys won't change anything if set correctly.
Changing it to the values of FFFFFF is just not right. That's not the size of L1, L2 and L3.
Forget this tweak boys. It's not doing anything and in the worst case you will mess up your cache values to something lesser than it is, because windows might decide to revert to some "default" values that are less than 5800X3D can deliver.
Show me a LDAT test end to end latency of improvements or go away.

This is an issue that likely only affects AMD. Task manager should show the cache numbers for your CPU, not sure about AMD but Intel will show different caches sizes either e-cores on vs off. E-cores have an additional cache that get enabled/visible in windows when they are enabled.

Reference:

"We fixed an L3 caching issue that might affect performance in some applications on devices that have AMD Ryzen processors after upgrading to Windows 11 (original release)."

So is this for AMD only? Is this for Windows 10?
