Some tips for you:

• Check game compatibility using https://www.protondb.com/ this will let you know if the games you want to play run on Linux and how well they do so

• Buy an AMD GPU, support for Linux is great on them, miles ahead of nVidia. If you already had an nVidia card it's usable, but if you're starting fresh 100% AMD.

• Don't fret too much on the distro of choice, not sure how familiar you are with Linux but because of the questions I assume not much. If this machine will also be used as a normal computer prefer a general use distro (my recommendation would be Mint), if you'll plug it on the TV and use it as a console prefer a gaming distro (I've heard good stuff about Bazzite but never used it myself). You can have / and /home be different partitions, this means that you can distro hop and maintain your games, saves, and most configs from one distro to the other, or even when reinstalling the system, I strongly recommend people to do that.

• Linux is not windows, things are done differently and that's okay. A lot of the frustration of new users comes from trying to do things the windows way and failing miserably, e.g. trying to install programs/drivers by navigating to a random web page and downloading a binary.

Good luck, and ask any more questions you might have.

Go with AMD GPU, be prepared for true happiness.

How much is the speed drop from translation using Proton?

The speed drop is negative. That is, it's often actually faster.

Yes, I know it doesn't seem to make sense.

For the most part you would just build the same machine as if it was a Windows gaming machine. That said, there are a few things to know:

• AMD has historically had better video drivers on Linux than nVidia, though nVidia has made some changes that has improved things quite a bit
• You want a basic, well supported common distribution if you’re not extremely familiar with Linux. Don’t go with some weird niche distro because you heard it will get you 1% better frame rates. Things like Steam and Lutris are well supported on the common easy distros. I would suggest Mint as it is Debian based, and basically everything supports Debian derivatives.
• Not every game will work, but a whole lot will. The things that are most unlikely to are competitive online games with anticheat root kits. If those matter to you, then unfortunately you’re better oft in windows.
• Take a look at https://www.protondb.com/ for a list of what is well supported and any information if they need some trick to run.

How much is the speed drop from translation using Proton? Is it so big or just small?

Honestly, in some cases, proton is faster than games directly on winblows. Microslop even said they're going to try to make windows faster than proton again.

I got broke by just reading the title.

As far as distros are concerned, Bazzite is a fantastic starting point because you almost certainly can’t go wrong. If you run into programs that need a kernel module or superuser permissions, just distro hop. It’s very likely that in your first time using Linux that you’ll not need those power user things, so Bazzite will be rock solid for you.

Also, in Linux, best practice is to set your home folder to be a separate partition on your HD. You can point your distro to the existing home folder so if you distro hop and you won’t lose your desktop environment prefs/setup or your files.

Here’s my notes on this for Fedora if you need a guide:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=geekbench6 com.geekbench.Geekben
ch6

AMD gfx cards cannot meet or exceed 5080/5090 cards. That said, I think a 9070xt is the best choice right now, because it’s probably going to be cheaper overall to just upgrade in 3-4 years rather than buy a 5090 and hold onto it for 10 years or whatever. You do you, but for me, I think upgrading early is the better choice since 2 flagship AMD cards should equal the price of the nvidia 5080.

Most games I just click play and they run.

Ryzen 9 x3D, XFX Radeon 9700 XT, 32 GBs RAM, with some flavor of MSI mobo I am too lazy to get the box out to look at.

It took me like a year to build as I was saving for all the parts (and the everything crisis began, at the time called the RAMpocalypse). I think it was around 3K to build then including the 2TB M.2

I'm never going back.

You picked a terrible time. Hope you luck out on components though. If you try the Chinese ram, tell us how it works?

Apart from other things said here (e.g. AMD GPU), if you are planning on using wifi check that the adapter works well. Intel wifi usually works very well on Linux (although I have read that there are some issues with their newer wifi chips). AMD mobos usually use some kind of mediatek chipset. It might be better supported now, but I ended up replacing mine with another m.2 wifi (intel ax200).

A quick search for general support from the mobo vendor is probably a good idea too.

I’m not enough of an expert to provide advice, but I can share what works well for me. I have tried games released across a 30 year span from multiple publishers using multiple types of engines using multiple launchers. I’ve had no issues with 240 Hz, an ultra wide display, or HDR. The one problem I’ve had is that the sound card doesn’t wake up properly after a long period of sleep, and so I double click an icon to wake it up. When I do, the Dolby digital 5.1 surround sound works perfectly.

I get better performance on Linux than Windows.

The significantly lower system overhead more than makes up for the translation layer.

I mostly game on Steam, occasionally Lutris. The only thing that just plain wouldn't work was Control from Gog - I probably could have gotten it to work if I played with the configuration. But I didn't really care that much.

I am using Bazzite for my gaming pc and am happy that it simply works

Not sure if you've chosen a distro, but I can vouch for CachyOS being pretty decent. There are more stable (i.e. non-rolling) gaming distros, but CachyOS doesn't take a huge amount of tinkering, and most things truly just work (I've actually had some games be less buggy on Proton than native Windows).

Games that run on Linux are about as fast on Linux as on Windows. In fact they tend to run a little faster on Linux.

Use AMD CPU and AMD GPU for the smoothest experience.
AMD CPU is more reliable, and Radeon graphics have the best support for Linux.

It is estimated that around 12000 Games work on Linux, or about 90%. For specific game compatibility you can always check protondb. Notice though that some games that have native Linux versions are also on ProtonDB, so you should check on the steam client first if there is a native Linux version.

https://www.protondb.com/

PS ProtonDB state the number of games that are verified to work as almost 9,900, and playable as almost 30,000 😎
But Platinum or Gold rated games are only 60%.

Personally I generally check ProtonDB before buying a game, but it's been quite a while since there was something that didn't work.

Don't you already know because you switched from Ubuntu to fedora or something last month?

Others have commented on performance, so I don't have anything to add. The parts/cost is really large and varied topic depending on what you're trying to do and what your budget is. And pretty much every part of my rig has gone up in cost since I got it, so no idea what it would cost to build at this point, but more than I'd be willing to spend.

So I'll just cover a few things you may run into issues with when trying to game on Linux.

Anti-cheat: Some anti-cheat software is not compatible with Linux or the developers didn't properly set them up for Linux. There isn't anything you can do to work around that. Just the way it is.

Some launchers/DRM: Ubisoft and EA seem to be big ones for launchers that are broken regularly. There may be others as well, but those are the ones that come to mind. You can sometimes get them to work by switching to different versions of Proton, but it can be hit or miss.

Niche gaming hardware: Some niche hardware like steering wheels, shifters, pedals, flight sticks may have some issues. Some work right out of the box, some work but can't have software/drivers updated, some can't be customized because of proprietary software that is windows exclusive. This hobbies have some pretty dedicated fans, and more of them are making the transition to Linux. So you might be able to find assistance here on Lemmy or on various forums if this is something you're trying to get working.

You may run into other minor issues but there are a ton of resources out there to get games working. Most will rum pretty much like they are native. I think Linux is a fantastic platform for gaming, and it will likely continue to be better as more people adopt it.

Go back in time a few years when it was affordable.

I switched from win11 to cachyOS a few months ago and are never going back. For gaming it just works, my only struggle right now is some audio configuration to get a virtual amplifier for my guitar to work.
But troubleshooting on Linux is so so much better than on windows, because 99,999% there's a solution in comparison to windows were often it's just "well, we disabled the solution to the problem, so tough luck".

I'm running 32GB ram, rtx4080 and a 5800x on a dual monitor setup (32" 21:9 and 24" 16:9). Was basically plug and play.

I don't get the hate against Nvidia GPUs.. i have been using Linux for 3-4 years on PC and Laptop with RTX 3000 and 4000 series and it just works. Even with Cuda. Apt or pacman just give you the right driver (havent tried other package managers..) I understand there were problems, but is it really deserved nowadays? Just go with whatever gives you the best price/performance?

You will have a better time with an all amd system (amd cpu's are just currently better, and amd gpu's are more linux friendly)

Every game that I played on windows, I can also play on linux

Build your pc with at least 2 drives, with 1 drive ideally just for the operating system. Not the end of the world if you cannot afford that, but it does make things easier long term, the same applies to windows installs.

Ignore anyone who tells you to use mint as your distro, they are either trolling you, or trolling themselves, it's trash.

Don't expect to find the distro that suits you straight away.

Don't judge all of linux based on the choices you initially make.

Don't listen to trashtubers like linus

If you are coming from windows, the desktop environment 'kde plasma' should be your first choice (as opposed to gnome, xfce, cinnamon etc etc)
