Really Poor Performance Issues - Top Spec PC (over £8k setup) - ~20fps

After much messing around with settings, found that my CPU Core Cache Ratio Multiplier had somehow been reduced from 32X to 20X. Changed it to 40X and this seems to have solved the majority of issues. Still not able to run everything set to ULTRA at 3840x1600 Resolution, which, I would have thought should be quite easy for a system of this specification. At least managing a playable average of 40-50 FPS running at a mix of HIGH and ULTRA settings with RAY Tracing and DLSS set to Quality Mode. Hope that they issue a patch soon that will improve the performance of the game engine to allow me to achieve 100+ FPS with all settings at ULTRA. Although, planning to upgrade to Intel i9 12900K Alder Lake with DDR5 and an ASUS Maximus Z690 Extreme Glacier Motherboard very soon. Not many options available right now for upgrading GPU, will upgrade CPU and RAM first and then add a newer graphics card when they are released. 

I do find it strange that only Battlefield 2042 seems to be affected by this setting. I’ve been playing Call of Duty and quite a few other games these last few days and they have all been running at Ultra Graphics and running at 100FPS or more.
