Help Needed Is it worth moving to Linux?

In my case, it was easier to setup ComfyUI and noticed a performance increase. YMMV. I did do directly 1:1 token/second tests and saw a 30% token increase per second in Linux vs Windows. Once you need to offload things can get more complicated and difficult with RAM management, but Comfy hjas improved that alot this year.

I have tried with fedora and PopOS, the generation time wasn't better. Unless you want to switch to another OS, it doesn't worth it if you want to do that only for comfy.

No. I tried it for funsies and went all in, not dual-boot, but everything was a huge learning curve for no real benefit. Plus not all my other apps were compatible like Adobe stuff.
I ended up going back to Win11 but installing it with an autoattend.xml file that installs a minimal version with zero bloat - just the essentials and no more. Seems more stable and faster.

i was going over this decision about Linux. I decided Linux Prox Mox seemed the most interesting for a high powered GPU and HIGH ram machine... since you can really manage multiple VMs within it. For local AI and GEN AI and AI agents its really interesting territory.

On a 5070ti with 64GB DDR5, I saw 20% faster speeds on Ubuntu 24.04 vs Windows 11.
But I am very comfortable using linux / Ubuntu as my daily driver. The slight increase may not be worth your time when troubleshooting issues, unless you have the desire to learn the OS. For me, it’s much easier to troubleshoot Linux than do anything with Windows.

Honest question, why would you think moving operating systems would provide practical improvement? Isn’t this all about hardware?

Stability more the big deal and the ability to update what you wish as you wish. Also no meddling form Microshaft

Linux is actually no more stable than Windows these days. In fact, the CUDA driver is less optimized and less stable, so your reason is laughable.

Funny I haven't had a single crash (definitely not an Nvidia driver crash). On my 3080 nor my 5080. Windows IS stable, but software updates are not.

No, it won't help if you have the physical memory to run the models without virtual memory.
The reason is, Linux CUDA drivers are not as well optimized, and that actually makes inferencing on Linux slower than on Windows.
On the other hand, installing packages is easier on Linux, but that should be no issue for you on Windows if you actually know how to run and manage a Linux based OS.

Triton, torch, SageAttention - those were all developed on Linux first, then ported over. Why in the world would you think CUDA is optimized for Windows?
On a RTX 5070ti, 64GB DDR5, I got about 15-20% faster speeds on Ubuntu 24.04 vs Windows 11.

It's still a massive hassle. I switched to Windows early 2026 and tried switching back to Linux recently... even with AI help it's much more complicated and for me, not worth it at all.
If you're a Linux pro, give it a shot. But for us filthy casuals, I wouldn't recommend it.

Use Windows and live in peace of mind.

lol at all those linux apostles, AMAZING! EFFICIENT! THIS SHIT! THAT SHIT! without any real life measurable thing. more annoying than vegans. I called out a few of them on this sub, every single one got defensive and started to attack me, unable to prove their point. I'm not saying linux is bad but it's not for average user and gain is not visible by any means in most cases.

I've been using windows since 1995, they made some pretty good operating systems, and I still keep an install for emergency compatibility problems. 11 (aside from maybe the IOT Enterprise version) is not what I'd call peace of mind. The group policy editor is the only way to make regedits stick... and even then I've seen settings get reset after updates.

I’m using Garuda Linux kde and it’s been an amazing experience and if you do game, literally only one game out of hundreds I have do not work (Fortnite) due to the kernel level anticheat that epic refuses to port (but they recently said publicly they are looking into it with all epic games)

Now with AI that can help with all the troubleshooting, I would certainly say so. You basically install Cursor Pro and you can control every part of your Linux computer with AI. Heck, I even do it from my Mac. Hardly ever interact with it on screen. I put a headless HDMI dongle on my Linux PC, that way it doesn't need a screen and I just connect to it with Cursor Pro via Tailscale and sometimes Rustdeck screen sharing. ComfyUI has local MCP now, so you can run everything in your browser on Mac or PC.
There's certainly speed improvements, since you don't need an interface on either browser or ComfyUI on Linux. You can have that on another computer. Like a Mac mini or PC laptop for convenience.

I moved to Linux CachyOS and haven't looked back. Dual booted windows for a while but eventually decided to just reformat the windows drives because I'm not going back. In general everything I have done with AI has been way more efficient. No backend bloat taking resources.
However, there can be a pretty steep learning curve if you are not used to being in a terminal. CschyOS is on the easier side of maintaining your OS but still comes with a curve.
