Oh thats because you forgot the pentagram of lit candles around the computer. Friggin’ noob.

But really though the only thing I can think of is that you are running your own NTP server that you forgot about and it’s having a bad time?

That...is strange. What specific flavor of Fedora was that?

Well... ok, let me try to respond broadly, first, then more narrowly, second.

Nvidia drivers are also shit on Linux.

To install Nvidia drivers on Linux, you actually have to install an entire custom kernel, much of which is propietary, not open source, other people cannot see the actual code.

This means that you basically have to pick a particular Nvidia driver/kernel, and build a Linux OS around it... with the added difficulty of... if Nvidia updates its drivers, well now the OS has to check literally every possible thing they could have changed, while not being able to directly see those things that may or may not have changed.

This... is significantly harder to do to a 100% OS stability/functionality assured level... than with AMD, who open sources their entire Linux drivers.

(I am not sure what the status is here for Intel GPUs)

So, yeah, basically, a shitty broken Nvidia driver update, on Linux, in comparison to Windows, has the additional capacity to potentially break literally all of your OS.

There is an open source version of Nvidia drivers, the Nouveau drivers, that are much more broadly compatible with various Linux distros... but its basically unofficial, a bunch of people trying to reverse engineer the official, blackbox, propietary Nvidia drivers.

So... it usually significantly lags behind the propietary drivers in terms of up to date features and optimization and newer game support.

There's a good write up on this here, if you eant more details:

So, IMO, a more sane approach than just going bleeding edge with your Nvidia driver/kernel, is to use an OS that semi-regularly rebases itself around the latest stable Nvidia driver/kernel.

Of the OSs you listed, Bazzite is the most straight forward and also reliable, in that way.

Debian is exceedingly stable, but, requires you to learn learn how to use it properly... you have to find an Nvidia driver/kernel that is basically compatible with your version of Debian, then stick with that untill Debian does a full new version of itself, about once a year I think.

Nobara and Cachy are basically bleeding edge; more frequent updates to latest Nvidia versions, but also this means greater chance something breaks and doesn't get noticed or fixed for a bit.

Now to try to be more specific:

When you say you only ran into timezone issues on 'fedora', do you mean standard mainline fedora?

Or does that include Nobara and Bazzite? They are both based on Fedora, basically customized versions of Fedora.

You also say your main use case concern here is WarThunder and Squad 44, the latter I think meaning the WW2 submod of Squad? Or is it actuslly a fully distinct game at this point... I haven't kept up.

(Ah, apparently it is its own thing now!)

So anyway... both of those use kernel level anticheat.

Kernel level anticheat tends to not play super well with Linux. Because... well now we have another thing fucking with the kernel, in addition to Nvidia!

Another thing that is not open source, that is a black box, that works in ways other people don't know about, and can again change something rather important, which can potentially break a lot of other things.

It is hard to build an OS around kernel cores when the kernel itself is a mystery to those designing the OS.

While Squad proper implements EAC in a way that does work on Linux, Squad 44 doesn't appear to. So, Offworld would have to... do that.

WarThunder on the other hand implements BattleEye in a way that works on Linux, but my guess would be they have not prioritized optimizing it much.

I dunno, what uh... what kinds of frame rate and such differences were you getting on which OS and which gfx settings vs ... same gfx settings on Win10 or Win11?
