  • Yes and no. As my physics professor used to say, all models are wrong, our goal is to make the least wrong model. It’s literally impossible to simulate every event. For example, what if there was an anthill under the area where the rock is dropped? Maybe that will affect the resulting sound? Maybe, but it’s not going to make a difference to the observer.

    We know enough physics to simulate a huge number of simultaneous events, but at some point a model becomes far too complicated (e.g. taking a week to run on a powerful computer), when a more simplified model will do the trick just fine. I personally compare it to FLAC and MP3–FLAC is of course best quality, but will eat up a ton of storage space, and MP3 (with compression) is good enough

    I’m using the Surface Laptop Studio with EndeavourOS (basically arch, so I have all the latest packages)–the performance issues stem from Nvidia’s drivers, so AMD should not suffer from the same problems, although I don’t have any AMD cards to test if hotplug with monitors is functional

    I have extensively used an eGPU (Razer Core X) with an Nvidia RTX 3050 for gaming under Wayland. Using X11 gave me nothing but problems, but Wayland allows for full hotplug capabilities (as long as no monitors are ever connected to the GPU).

    Of course, performance is fairly bad with the official Nvidia drivers + Wayland, but it’s good enough to play The Outer Worlds and a few other single player games, which is good enough for me! I have been entirely unable to get external monitors to work with the Nvidia driver (any help would be much appreciated), although they did work (coldplug) with the Nouveau driver.

    When I was using Windows, I was able to hotplug/unplug the eGPU with monitors attached, effectively turning the GPU into an external docking station–I am closely following driver improvements, as this would be great to have on Linux to get around the 2-monitor limitation of the Intel iGPU.




  • especially flickering and performance

    If my experience is any indicator, your GPU is fine :(. Any chance you’re using mixed display scalings? I’ve got an RTX 3050 eGPU for my Plasma/Wayland laptop, and for the most part it actually works fairly smoothly (albeit more slowly compared to windows), but if I try to run a game at a higher resolution than my monitor (used by Plasma for mixed scaling) I get constant flashing/frame shifting, but when I drop it down to the native 1080p it starts working again

    As a side note, X and eGPUs do not play well together, but Wayland is literally plug and play after installing the drivers–I can even hot plug/unplug as long as nothing’s using the GPU!
