Severe FPS drops after recent update – RTX 4060 Ryzen 7 5800X

Battlefield 6 has suddenly become nearly unplayable due to severe FPS drops.

Previously I had stable, playable performance using the exact same graphics settings and got around 100+ FPS. The issue has become much worse today, with FPS frequently dropping to approximately 30–50 FPS.

System:

RTX 4060 8 GB

Ryzen 7 5800X

32 GB RAM

2560×1440

During the problem, Task Manager showed approximately 69% GPU utilization and 52% total CPU utilization, with GPU temperature at only 66°C.

Most importantly, I lowered the resolution from 2560×1440 to 1920×1080 and FPS remained essentially unchanged. This strongly suggests that the issue isn't normal GPU limitation.

Standing still I can see around 50 FPS, but simply moving can cause FPS to drop into the mid-30s.

I have not changed my graphics settings compared with when the game was previously running normally. Changing between fullscreen/windowed using Alt+Enter also made no difference. The game was still reasonably playable after the recent update a few days ago, although performance may already have been somewhat worse. Today the degradation has become severe.

Is this a known regression with the current version? Any solutions that could help me? I've also tried restarting the PC, clearing cache and updating graphics drivers again but with no result...
