Plasma is the desktop environment developed by KDE. It's for example desktop environment used by SteamOS 3.
As to how you learn this stuff: looking things up on the search engine of your choice helps. Not trying to be rude here, but you could have found all of that out yourself by searching for "plasma Linux": https://lmddgtfy.net/?q=plasma linux
Also the arch wiki. There you can find all the info you could ever ask for.
" just use Linux" is a great piece of advice for most people because most people don't care about the OS they use. They just use it. And they shouldn't need to take a course to do so. Of course you are missing some things with this.
If you want more than you will need to go out and actively look for it
Sorry i didnt explain myself well and no dont worry youre not being rude.
My point wasn't, "what is this i dont know please tell me" but more in line with "how do you guys keep on top of this information and know whats current"
Some games support it on windows but not Linux. The list is small. That said, windows HDR support is garbage ime. I don't feel like there's a good option that's set and forget in any case.
Plasma/wayland integration is coming along but it's not there yet for HDR in gaming.
I just said screw it and live without it. Forgot i cared after 20min.
Not sure why you're getting downvoted. It literally only exists on a single desktop environment and even then it's practically beta. On my TV it just shows everyhing as green and purple when I enable HDR.
I love linux and want it to keep improving but man people need to stop circlejerking linux so much when it comes to people using windows when it suits their needs
It's true that HDR support is virtually non-existent being limited to very recent KDE wayland with bleeding edge everything and AMD hardware. Basically .33 * 0.05 * 0.3 or like 1/2 of 1% of Linux users.
It's also true that is a weird ass thing to chose a desktop OS for.
The Steam Deck is an exception to the rule, unfortunately. Game mode runs using Gamescope as the compositor, which allows it to directly manage rendering surfaces and support HDR output.
Support for HDR under a regular DE is still either nonexistent or a work-in-progress last I checked.
It takes some fiddling, but I've been using HDR on Linux since Plasma 6 came out. If you don't have an AMD GPU it would probably be really difficult to set up though.
It gives a nice visual pop but in terms of playing, there's no edge to it over standard.
Also it does exist but implementation is defined by the program which usually is only set up for the windows implementation. So you can wine the windows version of the program if you want it. I'm sure proton will figure something out soon.
I guess it really is an unpopular opion. Lol. I have have eye fatigue issues with HDR too, though.
I also can't watch 3D for more than 5 minutes without getting a migraine. I don't know enough about how the display works to know why. Both feel like it is trying to fool my eyes and my brain doesn't like it. Maybe my eyes/brain get fatigued trying to play along. Some types of HDR seem to bother me more than others. I can watch an HDR movie mostly fine.
