Total Performance loss
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
