Topic: Same Hardware Linux vs Windows version. min latency?

I am a prospective user.
I am not going to use Apple for anything. So "use a mac" is not helpful.
TL;DR: Is there any/enough latency difference in a linux install to make it worth the hassle over windows?

I am considering creating a dedicated pianoteq system with a few features:
1) minimal latency
2) quick GUI interface
3) likely on a recent low-end thinkpad - either current windows or recent linux on it.
4) works with Yamaha CK-88
5) can be updated over time both OS and Pianoteq (reasonably until end-of-life of hardware)
6) total cost (including thinkpad) < US$1000.
7) system would be fully dedicated to Pianoteq, no other DAW or anything significant installed on it.
8) this is primarily for high intermediate or low expert level practice. RCM 8+.

I am (extremely) competent with linux, but I do not enjoy fooling around with it. So, I prefer not to mess around much with settings or to optimize via the trial-error-research-banghead cycle that often occurs. I'd rather spend that time practicing. I am happy to follow a howto if there is one out there ( such as https://wiki.linuxaudio.org/wiki/system_configuration ). A prepackaged distro/bundle for pianoteq would be even better.

I have read that windows has hardware limitations on sound "cards" that increase latency and just in general, windows is less tunable for process management than Linux is. Additionally, I'd spend some time optimizing windows and uninstalling all the extras (this device is 100% dedicated to pianoteq). Windows prep would be less work than tuning linux, so in comparison, windows would be more ready out of the box, but may not be able to minimize latency like linux, and I guess that is my question to the group.

Is there any/enough latency improvement in a linux install to make it worth the hassle over windows?

FYI, I am considering this setup versus a (more expensive and older) fully managed hardware expansion such as Dexibell SX8, or possibly but unlikely a V3 Piano Grand XXL.

I'd love the actual experiences of people that have used linux and windows and if they see a difference and if they find linux to be reasonably robust?
TIA

I would say the hassle is clearly windows, which is a pita to install, avoid the traps of every 30 days trial of this bloatware, enter your credencies here and there.
You know linux ? Go Debian 12, almost no need to update. It's a set it once and enjoy. Just be sure to have your user in the audio group and set limits.conf as pianoteq says to.
Cheers.

Regardless of the O/S, getting low latency is all about the performance of your MIDI and audio interface hardware, their drivers, and the bus by which they're connected to the host. I would choose the O/S that gives you the broadest choice of I/O hardware which is pretty clearly Windows, I think.

Totally true.

That was maybe true 10 years ago.
But most importantly you don't need the *broadest choice*!! What do you care about the support for the 723 audio interfaces you don't own??

You care that the two (or maybe even one!) piece of hardware you have decided to buy are supported. And you care that support (driver) are solid, stable and blazing fast.

That was the case for me when I used a Foucrite Scarlett Solo under Linux 4 years ago. At the moment I am not using anything so I can't comment on most recent improvements (if any) with either OS.

I prefer not to mess around much with settings or to optimize via the trial-error-research-banghead cycle that often occurs.

Frankly, that was the case 15 years ago, now it pretty much everythings works-fine-out-of-the-box and optimize-by-following-documentation-or-blog-posts. At the time (4 years ago as said above), it was actually *much* harder to do this for Windows than from Linux!

But most importantly, in my experience (not for audio, but for anything else my experience is current), windows "pull the chair you are seated from under you", i.e. constantly changes things and forces you to re-do the same thing over and over or learn whatever crap they decided to change. With Linux, once you have made the (limited) effort to configure it correctly once, things stay as you set them forever. If I weren't forced by work, I would never use Windows.

Where do I find a list of all posts I upvoted? :(

The point was to have 723 to choose from in the first place... or at least some reasonable number from an array of reputable manufacturers. Admittedly I don't know what the state of audio/MIDI hardware/driver support is for Linux now. If it's reasonable, just go with the O/S that's the most familiar, neither is going to make or break the latency performance. The devices on the MOBO that determine bus performance and (and DPC latency in the case of Windows) are also more important than the O/S itself.

Re: Same Hardware Linux vs Windows version. min latency?

I've been using Linux (Ubuntu Studio) for over five years and I don't think I'll ever go back to Windows.

For working with music, Linux distros are much more fluid, with low-latency or real-time kernels.

I don't know about other software, but Pianoteq with Ubuntu Studio is a perfect match!

Respeito, Esforço e Sabedoria

Re: Same Hardware Linux vs Windows version. min latency?

In my experience, Linux had slightly better performance compared to Windows on the same PC. I used a laptop that was somewhat weak on the CPU side and occasionally experienced CPU overloads in Windows, but never in Linux on that setup.

With a reasonably powerful PC, there is no appreciable difference.

That said, latencies are similar. Some time ago, in a thread, other users and I posted some comparisons. The main difference at that time was that when changing the buffer size, latency increased more in Linux than in Windows.

That's pretty weird. Latency should just change by the difference in samples between the two buffer sizes (times two for RTL) unless the interface driver is adding 'safety' buffers as some do. But in that case, the result should still be the same for a given interface.

Re: Same Hardware Linux vs Windows version. min latency?

I did not measure latency difference. But I agree with others here. Linux is much easier to tame. It is possible to control what exactly running in the OS. Windows is a mess. Surprisingly it is also harder to set up a low latency environment. Midi drivers are not great. ASIO can be painful. In Linux default pipewire config works with low latency so that I didn't bother to customise it.

Linux can also have better hardware support. I have a microkorg bluetooth keyboard. It just works in Linux. I couldn't manage to connect it Windows via bluetooth. Although this is mostly on Korg having terrible windows drivers.

However, Windows has better commercial software support. Pianoteq is an exception having great Linux support. Most other VSTs require wine to run and that is hit or miss. And even it works, things can break after updates.

So pros and cons to each.

Currently I use an old surfacebook running Pianoteq and Mobilesheets. It sits on the music rest. I like the setup. I have to say Windows 11 touchscreen support is fine, probably better than any Linux DE. But I have to ignore daily reminders about Windows being Windows. Recently it started to show some ads via notification popups! I am pretty sure I can disable it if I spent some time to figure out. But why I have to fight with my OS constantly.
