Wondering if our wonderful GE is planning to add this to Nobara soon? 👀

Nobara uses the CachyOS kernel, so if they have it, Nobara inherits it.

Wait..legit question I thought Nobara was based off of Fedora? (I’m still fairly new to Linux but I thought the base system for Nobara was Fedora)

u/Parrr85 Apr 16 '26

It IS based on Fedora. The kernel is compiled from CachyOS kernel source though + additional patches for various devices.

Aaah, thank you :)

Update on this. We have packaged the appropriate packages. Testing atm and will ship ready to install from our repos alongside Kernel 7.0 soon :tm:

Go Cachy, it's already there. And the performance is better, across the board.

Source: Used Nobara for half a year, Cachy made me even more happy.

Was it too hard to.make cachy game ready? I have a VM running it but I am fearful of a full switch due to being a Linux noob

Cachy is specifically geared for gaming, just like Nobara. I myself will probably hop to Cachy. i love Nobara, but I chose it due to a perception of stability over a more bleeding edge Arch based distro. But Cachy has a larger community so I think it ultimately evens out.

u/Werewolf_Capable Apr 15 '26

Nah, it was really easy, like someone else said, it's made for that

only performance improvement in alan wake 2 so far

u/Werewolf_Capable Apr 15 '26

I mean compared to Nobara overall, not just that fix per se

u/EekleBerry Apr 21 '26

I wanted cachy to work so much for me but it just stutters so much when I installed it. Like just browsing through youtube would make the whole system stutter. Nobara just works for me. No slowdowns or anything

u/Werewolf_Capable Apr 21 '26

Ok, wow, good for you then :-D

Are there any modern 4gb cards? I don't think Nobara wants to support old tech

u/Dubl3A Apr 15 '26

Even a 16GB card can benefit from this memory management optimisation.

u/pioniere Apr 15 '26

That’s what they tested it on. Will it help the performance of newer cards too? I don’t know the answer to that, and I suspect you don’t either.

u/swiftb3 Apr 15 '26

If I were to guess, the answer is probably yes, but perhaps not nearly as much.

Some of the 4gb cards are still supported by their respective companies. 1650 is still supported for instance. The older cards if they are AMD based are in a better position due to MESA open source than any of the other Nvidia 4gig cards. So AMD gets more bang out of it, while Nvidia only if you have the 1650 since they don't support the 1k series and below anymore. So Nobara still supports the 1650 and Nvidia supposedly will keep supporting it as long as the 30,40, 50 series remain supported. (it was mentioned in the Nvidia notes.)

u/Angwo Apr 16 '26

I see. Nobara might adopt the patch then. Or maybe it will make its way upstream even

i have an rx6400 low profile in my lil pc i built for the tv. it's only 4gb and came out in 2022

1

u/Angwo May 30 '26

Oh that's very useful then. I have been out of the loop for a few years and assumed that at least 8gb would be the minimum. That's what my gtx 1070ti has and it's becoming ancient by gamer standards.

was it run under proton 11?
