As the title says, after updating to 20.1 my frame rate has gone to some pretty unplayable levels.
- Desktop PC with Manjaro 20.1 KDE
- Nvidia GTX 970 using video-nvidia-450xx driver (nuveau removed)
- Steam with some older titles like Wolfenstein Colossus as benchmark
I am not certain when the problem started manifesting itself, after the major upgrade or the kernel 5.8.6-1 (used to run 5.7.19-2). I ran into issues booting into 5.8 but that is resolved now.
I have since reinstalled nvidia driver and re-applied screen tearing fix. In desperation, I even tried to revert to a snapshot from a week back using Timeshift. Again, no change.
As a test, I decided to completely reload Manjaro 20.1 on a separate SSD drive (same system). I installed the same nvidia driver, Steam and the game and the frame rate is back to being great.
What can I check on my existing Manjaro install that is responsible for this reduced frame rate in game?
Any help is appreciated.
