So cpu is spiking ?
Yes cpu is spiking but it could just be DX12 shader compilation stutter since you just reinstalled everything. I would play through a few maps and see if the cpu spikes quite down. The stutters should be far less playing on a map the second time. Since most of the shaders have been compiled and cached to SSD the first time you play through a map.
Another thing you can do is put Battlefield 2042 in windows mode (alt + enter). Then bring up task manager (alt + ctrl + del) and set it to 'always be on top'. Monitor CPU usage and see if any cpu cores max out.
Hopefully it's just DX12 shader compile stutter and clears up after playing maps a second time. All the shaders need to be recompiled after every game patch and graphics driver update. So everything can be playing fine, then the graphics drivers get updated or a game patch comes out and all the DX12 shaders need to be recompiled again in the middle of gameplay. Such a bad design.
I suspect I found the issue, which is microsoft kb5029351 which was released on the 26th (issue started on the 27th)
https://www.theverge.com/2023/8/24/23844054/microsoft-windows-11-bsod-kb5029351-msi-motherboard-bios-update
they have pulled the update for now - tried to rollback with no fix
so refreshed windows (kept apps and files in place)
will try and play through a few levels and hopefully its just dx cache considering i cleared everything and every other game and program works fine, issue has to be 2042
Appreciate the support !

Flawless now
Many thanks
I'm glad it's working. Do you play in borderless window or fullscreen mode?
fullscreen - i know its weird it shouldn't effect it but that's the only thing i changed and googling it seems to be a common issue
