I recently changed my video card to AMD 6950 XT with all drivers up to date.
Oculus shows that "Your computer doesn't meet the updated minimum specifications, which can lead to a poor experience in VR". The refreshing rate of the VR is also unreasonably low.
Press the Windows key + R on your keyboard to open the Run command.
Enter C:\Program Files\Oculus\Support\oculus-drivers.
Open oculus-driver.
Open the Oculus app and then try to connect your headset again.
As for the performance, you do want to make sure those are set to default:
Open the Oculus app on your Computer.
ClickDevices on the left side of the app.
ClickQuest and Touch.
Click Graphics Preferences.
ClickReset to default.
Click Save and Restart
If nothing here seems to help out, you might want to get your Logs (See below) and reach out to the Support Team for other options.
To gather your Oculus logs:
Open the Run window (Windows key + R).
Enter and run: C:\Program Files\Oculus\Support\oculus-diagnostics\OculusLogGatherer.exe
The above link is the default directory. Bear in mind that if you installed the Oculus PC app to another drive you will need to update the command with the correct file path.
Select the checkbox next to ‘Full logs’.
Select "1 day" from the "Collect last" drop down list.
Wait for the log collection to finish. This can take some time to complete.
The program will automatically generate a zip file containing your logs, which will be saved to your desktop.
Attach the newly created zip file to your next support response.
The problem might be that you didn't completely uninstall the Nvida driver from you PC before you switched to the AMD card. There are windows registry files that can cause problems in performance if they are left on your PC. I use a program that FREE called DDU uninstaller that completely removes the drivers when switching brands of GPU's.
