I don't understand what AMD CCD is, I'm an Intel caveman. I just find it funny how some games can get there like Hatsune Miku Project Diva Mega Mix+ (Steam) which isn't even on Xbox, and other oddities like the Steam Version of Phantasy Star Online 2 not showing, yet the Windows Store version does.
And forget about it if you're playing a VR game, not even Half Life Alyx IIRC, LOL.
so some of the new ryzen cpus have 16 cores, which is compromised of two big 8 core groups. for exaple when core 2 wants to communicate with core 10, there's a performance penalty due to being in different clusters. but one point further is that AMD introduced v-cache, that boosts CPU bound performance immensely. but surprise surprise, some of their CPUs only have vcache on one side of the CPU. so naturally, the non v cache part would slow a game down, theoritically
so the v-cached 8/16 portion is already enough for games, yes? so it would be unpractical if a game hops threads around these two big 8 core groups, where one of them is slower due to having regular cache. so AMD and microsoft together created a way to make sure games only run on one CCD (one group of 8 cores) . so if game bar detects a game is running, their cpu scheduler only assigns the game to a single CCD.
its weird but its true
AMD has released its flagship desktop processor, the Ryzen 9 7950X3D, featuring the 3D Vertical Cache technology, which improves gaming performance. THe processor holds two 8-core complexes, one with ... Ryzen processor family

- Update your BIOS to the latest one available. This will ensure the intended performance and functionality of the AMD Ryzen 7000 Series with AMD 3D V-cache.
- Enable Game Mode in Windows by going to "Settings / Gaming / Game Mode" and turning it on.
- Update the Xbox Game Bar App to the latest version.
- Install the required Chipset Driver (version 5.01.03.005 or newer). After installation, restart the system and verify that the device manager has "AMD 3D V-Cache Performance Optimizer" and that the "AMD 3D V-Cache Performance Optimizer Service" is running. Also, verify that the "amd3dvcacheUser.exe" program is running in the task manager.
- Run "Process Idle Tasks" by opening the command prompt as an administrator and entering "Cmd.exe /c start /wait Rundll32.exe advapi32.dll,ProcessIdleTasks". This may take some time (up-to 15 minutes), so try not to touch the keyboard or mouse during the process.
- Verify the KGL Version Loaded by pressin"
I wont lie to you, this is one of the funnier shit I've ever seen in hardware history. imagine highly expensive, top of the shelf tech having to utilize game bar to detect games lol
