[Intel 12th/13th Gen] Severe FPS drops after June 23 update - BIOS fix

Since the June 23 Overclocked Midseason update, many players on Intel 12th/13th Gen CPUs are getting severe, unplayable FPS drops. I dropped from a stable ~230 FPS to around 60 FPS with heavy stutters, mostly in real matches.

My specs:

CPU: Intel Core i7-13700KF

GPU: AMD Radeon RX 6900 XT

RAM: 32GB

Motherboard: ASUS ROG Maximus Z690 Apex

OS: Windows 11

Symptoms:

GPU usage stays low (the GPU is waiting on the CPU) while a few CPU threads are nearly saturated. This looks like a worker-thread scheduling/synchronization regression introduced by the update. It is far worse in real matches than in the Firing Range.

Things that did NOT fix it for me:

Lowering all graphics settings, -threads launch options and +fps_max Unlimited, setting CPU affinity, verifying game files, and updating/rolling back GPU drivers.

The only reliable workaround (reported by many users):

Disabling Intel Hyper-Threading in the BIOS. This changes the CPU topology the game sees and restores normal FPS. Only disable Hyper-Threading - do NOT disable E-cores, and do NOT change any BIOS security settings. This is a temporary workaround until Respawn ships a proper fix; re-enable it once the issue is fixed.

How to enter BIOS by motherboard brand:

ASUS / ROG: Restart and repeatedly press Delete (or F2). Press F7 for Advanced Mode, then Advanced > CPU Configuration > set Hyper-Threading to Disabled.

Gigabyte / AORUS: Repeatedly press Delete. Press F2 for Advanced Mode, then Tweaker > Advanced CPU Settings > set Hyper-Threading Technology to Disabled.

MSI: Repeatedly press Delete. Enter Advanced Mode (F7), then OC > CPU Features > set Intel Hyper-Threading Technology to Disabled.

ASRock: Repeatedly press F2 or Delete, then Advanced > CPU Configuration > set Hyper-Threading Technology to Disabled.

In all cases, save and exit with F10. After rebooting, open Task Manager > Performance > CPU. If logical processors dropped, the change applied correctly.
