SCAgent: I have been wanting to try linux for a while now, been researching about it this past year, I hear gaming is very feasible there..
Was planning of making a thread but since I am here, any linux gamers out there how true is this? Any regrets? or favorite games you can't play?
First of all, I suggest that you don't "switch" to Linux, but do e.g. a dual-boot system so that there is always your old trusty Windows to go back to, if you need to. If at some point you feel you don't need Windows anymore, fine, remove the Windows partition. Or if you feel you want to totally go back to Windows, that is fine too, delete the Linux partition.
(And then try to figure out how to get rid of the grub2 boot loader, not that it is impossible or anything, but an extra hoop anyway, when changing a dual-boot system back to a single-boot Windows system...)
My limited experience with Linux gaming so far, meaning playing Windows games with WINE on Linux (older games mostly, not e.g. DX12 games, hopefully others will fill you on how it is to play modern DX12 games on Linux, I presume there is at least a performance hit):
1. To set up WINE properly, google for "<your Linux distro> install wine".
I originally just went to the Linux Mint Software Manager and searched for "wine", but then I got a long list of different wine... installations or utilities, with no idea what exactly I was supposed to install. I just selected some that sounded legit, but I think I ended up with an incomplete installation, at least I didn't seem to get Windows games running with WINE.
So later I uninstalled that and then googled for more detailed instructions, and they worked (easy to follow instructions, but it took many things into account that you will not know by yourself; a bit like you have to know in Windows 10 how to enable DirectPlay for older games to work). At some point I also installed e.g. Lutris which makes the installation of many games effortless, but I generally prefer first trying to install (and run) the games in vanilla WINE. If I have any problems there, then I may try Lutris instead, to install (and run) it.
2. Next google for "linux how to run program wine", "linux how to uninstall program wine" etc., just to learn how to do those basic tasks. Not hard, but if you don't know, then you don't know. :)
3. Generally I have been quite pleased running older GOG games on WINE. E.g. Icewind Dale 2 Complete runs even better in WINE for me, than it does in Windows 10, even with a DxWnd wrapper (that I need in Windows 10 to fix the game). Currently playing Starcraft, Planescape Torment Enhanced Edition and Team Fortress 2 (this on Steam, not WINE-related). They all run perfectly on Linux.
One hiccup was e.g. running GOG Diablo. I first installed it with vanilla WINE but the game didn't run correctly (e.g. couldn't see the game menu etc.). Googling for it, it was obvious some extra fixes were needed to run GOG Diablo on WINE.
So I uninstalled the WINE vanilla version of GOG Diablo, and then reinstalled it with Lutris, and the game works perfectly now. I think that "playit" option also works (instead of Lutris). So, yeah, GOG Diablo is one example of a Windows game that does not run "out of the box" in WINE, but installing and running it with Lutris or playit will install the needed extra fixes to get it running.
SCAgent: I keep hearing Manjaro is great for playing the latest games or Linux mint is also great for newcomers. I don't play online games, most of my library is here on GOG and steam for leftovers.
If GOG supported Linux more I would have made the switch years ago though.
I am using mostly Linux Mint (XFCE), Ubuntu-based.
I've been trying out Manjaro both on a virtual machine and on Raspberry Pi4 (mainly interested in it due to its rolling update model, ie no major release upgrades), but recently I've been unable to update that virtual machine Manjaro anymore, due to some dependency error... I hope that is not so common in Manjaro, it did leave a bit sour taste into my mouth. I guess I need to google how to fix that dependency error; I read before that Manjaro upgrades may become broken (= unable to update) if there is a long time since the last upgrade, but in this case there wasn't, I had updated Manjaro like a month before that.
Steam support is quite good for Linux, but my experience with it comes mainly from running Team Fortress 2, which runs just as well on Linux, as it does on Windows.
As for GOG games, I normally don't even check the Linux versions because:
a) I am unsure if the Linux version is up to date, compared to the Windows version.
b) Quite often the "Linux version" is merely the Windows version running in Wine... so what is the benefit of running that, instead of running the Windows version in WINE yourself? Case in point: Two Worlds. I was unable to get the GOG "Linux version" (= Windows version running on WINE) of it to run, there was some dependency error.
I had much more luck getting the GOG Windows version of the game running, in WINE. So e.g. in that case I consider the "Linux-version" of the game irrelevant, and even inferior.
