I’ve been playing Battlefield 6 since launch and refreshingly haven’t experienced a single instance of cheating in that time. I have EA Javelin to thank for this, the game’s anti-cheat. However, this system is affecting how my AMD Ryzen CPU operates, costing me some performance for the pleasure of a cheat-free experience.
EA Javelin is blocking my chip’s ability to engage core parking. For those unfamiliar with the phrase, it refers to the process by which a Ryzen processor parks one of its two Core Complex Dies (CCD) so that processes route to the most proficient die for the task. In the case of Battlefield 6 and most games, this refers to the 3D V-Cache CCD with a larger pool of L3 cache.
JayzTwoCents brought this issue to my attention, and I’ve since been able to replicate his findings on my own Ryzen 9 7950X3D. However, I’ve found that this issue only affects the game’s multiplayer modes, with Campaign operating as expected with core parking as EA Javelin isn’t running in the latter mode.
While this behaviour is undeniably causing a performance loss, it’s impossible to determine the extent. Using a tool like Project Lasso to force core parking across Battlefield 6 and EA Javelin isn’t worth the risk as it could trigger a false positive in the anti-cheat, resulting in a permanent ban.
For now, the only way to ensure Battlefield 6 is running on the 3D V-Cache CCD without issue is via toggling X3D Turbo Modes in BIOS. However, this isn’t a 1:1 replacement for core parking, as these features disable simultaneous multithreading (SMT) and cut core counts. Here’s hoping that EA and AMD can work together to make Javelin and dual-CCD Ryzen CPUs play nice.
Here’s a list of all processors that this issue affects:
- Ryzen 9 9950X3D
- Ryzen 9 9950X
- Ryzen 9 9900X3D
- Ryzen 9 9900X
- Ryzen 9 7950X3D
- Ryzen 9 7900X3D
EA tellingly forgoes AMD CPUs with multiple CCDs in its Battlefield 6 system requirements recommendations, including ‘Ultra++‘. Until a core parking fix arrives, the best CPUs for the game are Ryzen 7 9800X3D and Ryzen 7 7800X3D.
While I may be losing some frames on my dual-CDD processor, I’m in no hurry to swap the chip out for another. Credit to Battlefield Studios, the game runs butter-smooth on my setup and much as I’d welcome extra performance I’m more than satisfied with my current experience.
