Hey all!

UPDATE** With some further testing, I am noticing video content sometimes does not play on the Steam Deck. This is a shortcoming of Unreal Engine on Linux, where Linux (and even proton windows) does not play nice with the UE video codec. Working on a fix with a few plugins :)

At this time of writing, MOKM is currently operational on the Steam Deck, but does have low fps (averages around 20-30 fps on low to high settings, with screen resolution at 50%, changing graphics options does not make much of a difference).
So you can play MOKM on the highest setting on the Steam Deck, but it will be a bit slow.
I am working to address this in future updates. If you want the technical details below, scroll further.
Thanks!

Technical: MOKM runs on UE5.5.4. Unreal Engine is notorious for low fps on the Steam Deck. Many developers have significantly more skill than me in optimization (I am a concept artist lol.) but I have looked into some of the causes: The primary cause is likely how the current build of MOKM handles shadows. Even with Lumen turned off (the glowy window effect) the Deck still averages low fps. This is due to the fact that most of the shadows in the game art dynamic shadows (updated every frame) rather than static shadows (baked into the textures of the environment). I designed the environment and many of the 3D models before I knew about static vs. dynamic lighting. Many of the assets thus have some problems with static lighting. I have tried baking the shadows, but receive a plethora of errors that will take a few weeks to solve:
Shadows baked into places they should not be
overlapping texture UVs
Packaged build crashing on launch
Shadows not working at all?
So, will figure out in time, but as of now, it's a technical challenge I am facing.
If any developer has insights, email me at [email protected]
Thanks!
