So I had to reinstall windows to solve an issue when installing a new NVMe drive (windows was not recognising the drive as windows would default to a standard HDD controller, rather than an NVMe one after a few days of troubleshooting I found the issue, but only after a windows reinstall).
I have set my Windows install up the way it was previously and the performance of MSFS has dropped considerably. I used to be able to maintain 35-40fps on high/ultra settings. Now when I am in a glass cockpit performance is tanking. Down to between 15-25fps on low/med settings.
Currently running an AMD Ryzen 9 3900X, Radeon 5700xt, 32gb of ram at 3200mhz, windows on a Samsung 980 NVMe and FS on a 980 NVMe as well. Windows has had the bloatware removed, I am running AMD Adrenaline software, Razer synapse and cortex. I have tried with out cortex and it makes no difference. I am also running Navigraph with sim connect as well. Again have run MS with out this with no difference.
Any insight on things to try would be fantastic and appreciated.
