Pc experienced severe slowdown following the installation of 9070XT
Hi, today I upgraded my GPU from 1080Ti to 9070XT. The new card triggers a notification in BIOS about disabling CSM due to compatibility concerns. The issue arises when I turn off CSM, making the PC extremely slow and nearly unusable. I searched online and found that I should verify whether my SSD is MBR or GPT (which I confirmed it is GPT) and check the msinfo32 settings to see if the system boots in UEFI or legacy mode (it shows UEFI). Now I’m struggling to understand why disabling CSM would cause such severe performance drops.
If you're GPT and UEFI, it's not clear why your BIOS had CSM enabled initially. There are no unusual old devices connected. Check the Task Manager to identify slowdowns such as full CPU usage, frequency throttling, or heavy disk access. Make sure you completely uninstalled the NVIDA drivers before switching to AMD. You might try using DDU to remove all graphics drivers and then reinstall the AMD driver with CSM turned off to see if performance improves.
I assume 1080Ti was the original model. I didn't use DDU, let's try that instead.
