Proton / wine is modern day magic
Most Windows only steam games work out of the box (you do have to enable it in the right click menu > Compatibility options, per game)
Games that use Anti-cheat aren’t likely to work (it depends on the Anti-cheat used and how it’s configured)
ProtonDB is a good resource for checking if/which games work, or fixes and workarounds
You can use proton or wine on non steam games, but that requires additional setup that I’m not familiar with
Fiber?
I just did a quick search for coffee nutrition facts, and all resources say 0g of fiber
Assuming you’re using a paper filter, only water soluble particulates will end up in the coffee
And, water soluble fiber tends to be a thickening agent (porridge, Psyllium husk)
On what plane of existence is coffee a good source of fiber?
