What do you mean? There are the following:

Proton experimental Steam Linux runtime 1.0 Legacy runtime 1.0 Proton hotfix Proton 9.0-4 ....

If you mean just the global checkbox, yes that's on

Yeah I've tried several Steam Play options. I get different behavior from crashing to some wonky rendering of the windows behind it, but none work

Well I've installed BG3 just for the sake of testing and the DX11 launch results in a black screen. The Vulkan launch options crashing immediately...

Here is my steam logs when launching KSP I think the only thing of interest is this:

So steam play was already enabled, it looks like it defaults to "steam Linux runtime 1.0 (scout). When I select different versions of proton runtime I get different behavior dependig on which one I select.

Proton 9 says that it cannot switch to my monitors resolution,

Proton experimental and hot fix launch the game (I can hear it!), but things are ... Weird. It only renders the windows behind it and the custom game cursor. When I alt enter to bring it into Windows mode, it's still just the windows/desktop that would be behind the game but now it's scaled differently.

EDIT:

It's hard to tell but the above screenshot is the game window

Gotcha, today is the first business day since filing my ticket. They've requested logs but no solutions yet.

I don't appear to have this.

My goal for this system was to eject windows from my life prior to the launch of Windows recall. That and host a bunch of docker containers in an environment more reliable than windows. I got impatient waiting for cosmic to reach full support, but still wanted to go with the distro system76 ships as "theirs" as opposed to putting Ubuntu on their hardware. I haven't checked if cosmic is officially out yet but will likely switch over when it is. I'm a novice with Linux btw. I can use it to host and run my software but wanted a prepackaged solution for my devbox so that I have a much lower chance of breaking it. Also things like my Wacom tablet just worked out of the box, which is all big plus.

It doesn't appear to be set and additionally I don't appear to have the libgl1-mesa-swx11 package mentioned in that post.

This does remind me that while developing a webgl canvas based javascript app the other day I was forced to go into firefox's about:config and set webgl.force-enabled = true. I should have dug deeper on that.

Yeah I'm pleasantly surprised by the unanimous responses that AMD seems to be the way to go in this space. At this point I know it's not using my GPU at all, so you are right that nvidia wouldn't be any different

This is Pop_Os, which is System76's 'ubuntu like' distro that comes shipped with vendor maintained drivers. It comes preinstalled with steam and is intended to be able to use it right out of the box. I've opened a ticket with them to discuss it further

Now i'm starting to doubt since this these responses have been so ubiquitous, but it's definitely not plugged into the motherboard's gpu slot. The motherboard has a single hdmi and displayport port. It, like all the other motherboard ports have a matte-black finish that matches the case. The displays are plugged into the glossy silver PCIE aligned hdmi and display ports, which doesn't match the rest of the case. The card is doublewide, occupying 2 pcie slots and is labeled "ASROCK".

It's definitely plugged into the GPU. I've had plenty of opportunity to get acquainted with the back of my machine at this point. :,)
