Atlas Fallen Optimization Fail: Gain 50% Additional Performance by Turning off the E-cores

Action RPG "Atlas Fallen" joins a long line of RPGs this Summer for you to grind into—Baldur's Gate 3, Diablo 4, and Starfield. We've been testing the game for our GPU performance article, and found something interesting—the game isn't optimized for Intel Hybrid processors, such as the Core...

"The game scales across all CPU cores—which is normally a good thing—until we realize that not only does it saturate all of the 8 P-cores, but also the 16 E-cores. It ends up with under 80 FPS in busy gameplay at 1080p with a GeForce RTX 4090. Performance is "restored" only when the E-cores are disabled." - "With the E-cores disabled, the game is confined to what is essentially an 8-core/16-thread processor with just P-cores, which boost well above the 5.00 GHz mark, and have the full 36 MB slab of L3 cache to themselves. The framerate now shoots up to 200 FPS, which is a hard framerate limit set by the developer. "

Whoever wrote that piece could have been clearer. Is the game choosing to do something stupid? Is Windows doing something stupid? Is Thread Director doing something stupid?
