I’ve tried with the latest stable proton, and separately with Proton Experimental. I am running the latest Steam Deck OS and Steam software.
When I try to launch Motorsport, it will display the splash screen for a few seconds and then close. I have not been able to launch it ever because it never gets past the splash screen.
I tested every Proton version, including Proton Experimental and Proton GE, and Motorsport would never launch on Steam Deck.
Even with the update it’s still not working.
This is exactly why the Motorsport developers should fix the launch bug. It’s completely in their hands.
Steam Deck is a PC that exceeds that minimum specs. Cutting 3 million players out of the equation just because they can’t afford a 4090 would be bad PR to say the least.
Interesting. This launch issue is happening on PC as well. Game Launch Crash after Small Splash Screen due to Access Violation
Thanks for sharing! Looks like this bug is affecting more than just Steam Deck players.
In the past we’ve seen Xbox Game Studios talk-up their titles running on Steam Deck so it would be a shame to see Motorsport left broken.
I can just imagine how excited you were to wiggle your finger and write that. However, I am not under-appreciative of the discussion; but in the end, you’re reading what’s not being said (in that singular article) as conclusive evidence of something that’s being said.
I don’t know why you bother with this kind of person, it just looks like a windows elitist having an opinion on things they don’t have a single idea about.
The real problem there is FM doesn’t run on Linux, because they pushed the windows game service to install dependencies at the first start of the game. This is a two sides job, Pierre-loup griffais is investigating it ( proton dev ) as stated on his Twitter message there, but turn 10 studios might have a job to do there as well to give FH a built in sign in system to a live account linked to steam like in FH.
You can follow the compatibility in protondb as much as players will still keep an eye on it and post there if it ever begins to work, or the compatibility report on GitHub
I have no doubt the deck will manage to run it well enough to be enjoyed, rare are the games I don’t manage to run on my 400ish games played on my deck.
May I suggest you to have a look at the topic of OP’s primary post.
It will avoid you to spill your bile against the steamdeck uselessly and make progress a bit more on the problem they asked which is the game doesn’t launch and not the performances aren’t up to expectations. 
Just because something isn’t certified to work doesn’t mean it won’t. If we had only people like you, gaming on Linux wouldn’t be a thing today. I prefer to talk with people contributing than people who are constantly negative without real arguments.
Thanks for your very valuable insights, we’re closer to making it work because of you, it’s much appreciated. 
Be careful not to offend him. Someone already got offended and reported my replies to him on this topic.
Great points! It looks like you just identified the possible cause and offered a potential solution too Good faith contributors like you are the reason modern gaming is inclusive of more people than ever.
@C0REOVERRIDE a little update, I’ve contacted the official support, giving informations about the deck but also my gaming rig ( using Linux for quite a long time 
) they came back to me ( after giving me the classic useless troubleshooting, “have you tried turning it off and on again” ^^’ ), here was their final reply
I thought I’d share that, and I strongly invite Linux gamers to take a minute to give them the details of their own setup here ( mostly about the distro they use to play ), it only can help to make it happen faster.
Thank you for sharing!
This is helpful, thank you!
@TDS_Trefle This seems to be the same bug causing Forza Horizon 5’s failure to launch on Steam Deck after the recent Series 26 update. I would encourage you to vote on this suggestion as well:
Ah, but you see, lots of people on Steam Deck are willing to try FM. In fact, they do try, but there’s a bug that prevents it from launching.
Just following up on this point. These seem to be different issues because Forza Horizon 5 works on Steam Deck when using the latest Proton Hotfix (as of October 16, 2023). Forza Motorsport still will not launch, even when using Proton Hotfix on Steam Deck.
