You’ll want to change the compatibility for Black Mesa.
In your Steam Library go to Black Mesa > hit the gear icon > select ‘Properties…’ > Compatibility > and check “Force the use of a specific Steam Play compatibility tool”
Either select Proton Experimental or Proton 8.0-4 (latest ver.)
After that you’re solid. I had no problems running the game on ‘High’ for the Earth levels. Performance took a hit from Xen to the end though, so may want to drop it down to ‘Medium’ after that.
