Sid is having a nice discussion on other forum about GPU out of mem and Vulkan device loss, how they are not pretty much related. Also mentioned that some of these stutters are causes when the other threads suddenly get taken to task that the main thread will sometimes throttle, and cause stutters, they dont quiet know what causes it and it varies on CPU. Found this due to the 60sec stutter caused by weather update. Queit long posts.

And some reading

It's always really great to be able to read these posts from the development team, getting in touch with what they're working on, what they're doing to keep Xp12 at the very top in terms of quality support and development.

Most of the stuff they write is pure "Chinese" to me, but I like to read accross it and try to have an idea about it, but above all it is really great to be able to get that information from the core development team, instead of not really knowing what's going on behind the scenes ...

OTOH, the progress in terms of stability, performance and BEAUTY is incredible with this latest Beta !!! 

At it's present state I find the lighting, colours, feel of flight to be 2nd to none among the general purpose flightsim platforms I have EVER used.

X-Plane 12 is "THE FLIGHT SIMULATOR" !!!

Not sure if they simply manifest differently, but I've never knowingly run into a Vulkan device loss error on Linux (on AMD hardware, no data points for NVidia). Maybe the driver stack is less susceptible.

Ah! so you're on a Linux rig? If yes, which flavour / version do you use / recommend to run X-Plane 12?

Thx!

Personally, I run Arch Linux, basically a build-it-yourself LEGO brick distro. For beginners, Fedora is more plug & play and its KDE Plasma spin offers a UI experience akin to Windows: https://fedoraproject.org/kde

There is also a Fedora GNOME spin, but this is more for the MacOS crowd.

Note that most of X-Aviation's offerings (exceptions: C525 and CL650) and Traffic Global will not run in X-Plane for Linux.

Ok Traffic Global is a must have.

The other sim preventing me to go Linux ONLY at home is Condorsoaring3...

Seems to work with a bit of tinkering: https://www.condorsoaring.com/forums/viewtopic.php?t=22126

Theoretically, you could also run the Windows release of XP12 in WINE to use all of your plugins, but it might be easier to stay Linux native and use LiveTraffic to fill the skies. This has the advantage of saving some CPU cycles because there is no AI aircraft positions that need to be calculated locally.

Yep, I was aware of that "trick" for Condor3, but it doesn't run the Lx9070 and the Hawk vario properly 😕

I actually have my own post on that: Condor in Linux? - Condor

Won't cost anything to try. If you run their software and Condor 3 in WINE, it should theoretically work. (Condor3 in Steam/Proton is a different story.)

Sadly no. The last version of XP to run under wine was 11 in GL mode. The way GL is bridged into Vulkan causes problems now. And even if it did work, you'd be at the mercy of finding exactly what libs were used to build the various plugins. Some might have been be easy (for example just installing .net) but otherwise you'd essentially be in a guessing game trying to figure out the dependencies.

Trying to run XP's Windows installer in WINE, it's not GL, but rather Vulkan itself or the lack of information about a Vulkan-capable GPU in the system. I'm sure one could work around that in some way, but in the end, it's frankly a lot easier to stick to Linux native XP and simply not throw money at developers not offering Linux builds of their add-ons.

Wine offers full Vulkan passthrough. GL as well. That's not the problem. I use a windows game in wine that's a native vulkan renderer and it runs just fine. It's the GL bridge that is unique to XP, after the files are installed:

"An extension required to run the OpenGL bridge is not supported on 4.6"

I was surprised to see that even after zink entered the picture. Certainly not worth the effort to workaround. If that's even possible.
