Here’s some issues I found with your log that might help.

  • Due to AMD’s poorly optimized OpenGL driver, you may experience slowdowns.
  • Please enable the Vsync option if you are experiencing screen tearing.

Update drivers to 22.8.2: https://www.amd.com/en/support/apu/amd-ryzen-processors/amd-ryzen-7-mobile-processors-radeon-rx-vega-graphics/amd-ryzen-7

Please re-enable Hardware Shaders after you install the up to date driver. It’ll give you a nice performance boost.
