[SOLVED] Last Nvidia GPU binary driver update performance issues

I updated the box and the nvidia driver (and its related packages) were bumped to version 418.74-1.

Immediately, Dota2, a Steam game that uses Vulkan failed to start with

Failed to initialize Vulkan. Please make sure your driver and GPU support Vulkan.

I can start Dota2 and some other games in OpenGL mode and while the game loads, I get 1-2 FPS, compared to 120+ FPS before.
I can see stuttering in YouTube videos and a big drop in GPU performance.

I downgraded all of them to 418.56-1 but the issue persists.
I have not attempted to downgrade the many many Vulkan packages yet.

Should I try that next? What else could this be but a driver issue?

Re: [SOLVED] Last Nvidia GPU binary driver update performance issues

Update your system then reboot. When the nvidia driver updates, the driver version expected by the kernel module (which is still the old version) does not match what you have installed (the new driver version on your system).

To fix it you have to reboot into the new kernel and new nvidia module.

If that doesn't work post

pacman -Q linux
uname -a
pacman -Qs nvidia
dmesg

Thanks, upgraded and saw the error of the old module loading in dmesg. Recreated initrd and the issue's resolved!
