My specs:
• Intel Core i9-14900KF (24 cores / 32 threads, 5.8 GHz boost)
• NVIDIA RTX 5090 (24 GB)
• 64 GB DDR5 @ 7200 MHz
• Windows 11 Pro (fully updated, latest drivers & BIOS)
What’s happening:
• In Battlefield 6 I get ≈ 180–200 FPS max while the GPU is only 50–60 % used.
• CPU frame-time ≈ 5–6 ms, GPU ≈ 3 ms → clear CPU bottleneck.
• In Battlefield 2042 on the same setup I get ≈ 300 FPS Ultra with full GPU utilisation (≈ 98 %).
• Cinebench R23 ≈ 33 000 pts and 3DMark Time Spy ≈ 44 800 → system is top 0.5 %.
This clearly isn’t a hardware issue. It looks like a threading / CPU-utilisation bug in Frostbite DX12.
Other creators (e.g. The Tactical Brit on a 5090 + 9800X3D) show the same SIM-thread bottleneck, so it’s not isolated.
I’ve already:
• Reinstalled drivers (clean install)
• Tested DX11 vs DX12
• Reset settings (no user configs or mods)
• Reinstalled the game completely
What you can do is lower CPU heavy settings, cap FPS, slightly lower render resolution. It should reduce CPU load on the SIM thread, which helps feed the GPU faster, so it partially eases the bottleneck and lets the GPU run closer to full usage.
Your pc is to high end, until EA patches multi-thread scaling for the simulation thread, this is expected on ultra high end systems.
