For me, it’s Shared GPU memory.
Online games just working.
I know, I’m probably off better without Chinese and Korean rootkits installed, but Infinity Nikki looks so darn comfy to play.
Oh, and HDR and 144Hz. Both in X-Server as well as in Wayland, over a good DP, I can select 199.98Hz at best. Never managed to fix it. Same computer, monitor and cable used to do 144Hz just fine on Windows, before.
HDR is really gone, though, but I don’t miss that as much.
Windows update holding me hostage like the slut I am
Effort free gaming on Windows
I’ll acknowledge that gaming is much better than when I entered the field 20 years ago,
but it was so nice being able to just install a game and have it function instead of install a game and play the 50/50 gamble of whether or not it’s going to have some bug that forces me to go online and search the issue.
Proton DB has been a lifesaver for most issues that have occurred, but there are still so many games that have obscure problems that while not all of them prevent you from playing at all, a good portion of them have issues with them that dampen the gaming experience.
And as a bonus one, the lack of a decent Android emulator. I have tried so many different emulators for Android, and all of them work notoriously worse than BlueStacks did on Windows and a lot of times take up double the space it did. As a person who plays a lot of mobile games that require constant looking at, it was so much easier to just have it running in BlueStacks on the third monitor and then just look at it when needed
The lack of a good cad software (fusion 360), and no, freecad and openscad are not worthy equivalents.
