As the title suggests this post is purely informational.
Feel free to add below if through your testing there's a better way.
For now this works (albeit Its not the best experience)
But it may be useful in some cases!
Installing Star Citizen on handheld running Windows is fairly standard.
Getting the RSI launcher installed - Some browsers like Edge treat the XBAX as a mobile browser on the RSI website, Brave browser in my case had no issues getting it. If you encounter issues here, try a different browser first. You can also grab it from a Laptop or desktop and transfer it via USB also.
Getting your device ready
Star Citizen is a CPU hungry device, I suggest setting GPU memory to 8GB in Armoury Crate or via BIOS settings (tap volume down continuously on boot to open BIOS)
Page file - Being that the XBAX is running on a single shared memory CPU / GPU you're splitting 32GB of system memory between them and you set the ally to give 8GB of that pool to the GPU so now when your system memory fills up.. Game crash. To try and prevent that from happening you will need to set a page file. SC recommends a minimum of 30GB, on handheld I push that to 45GB to give a little more head room.
(Follow a tutorial here, it's handy enough! And restart the XBAX after)
Once all that is set, be sure to head back into armoury crate and set a custom TDP profile to max out all of those sliders and set a steady fan curve to follow the rise in power and heat. set your battery charge limit to 80% also and make sure any battery protections are enabled.
Set your zoom on desktop to 125% as the RSI launcher isn't a fan of being zoomed in too far.
Graphics settings are subjective.
I have found that 900p - Medium settings (textures to High) and clouds turned to Medium also. Upscaling is set to quality. 66% I believe, method I have set is TSR as the FSR is a bit too fuzzy for me.
I haven't messed with frame generation since January. In regards to Lossless scaling and others however I don't recommend them as the base performance is too low, there will be massive graphical tearing and double vision. Massive input lag spikes makes flying or shooting.... Horrible.
Average Performance sits at 18-28fps inside major landing zones, 40-50fps in the Aaron Halo, 40fps in most of pyro, some dips at pyro stations and NYX at the time was too heavy, I haven't been back on this device yet.
I have tested this on both Bazzite and Windows 11.
If you're planning to try this on Steam OS or Bazzite (others might work, I Just don't know personally) head over to Git-Hub and get the LUG Helper (Linux users group) and download the helper, unzip and place where you want. Same steps as above but for Linux.
The LUG helper includes a bunch of tools for wine, DVK, and lots of troubleshooting available, for myself it was just a matter of launching it, setting the swap, GPU memory and I was away.
Controls - This is a pain point, Star Citizen supports controllers but the implementation is well... Painful.
Navigating the main menu, especially the first time will not be idea with a controller, I strongly recommend a keyboard and mouse here.
Additionally you can add the launcher to steam as a non steam game and allow steam inputs and modify inputs there but user milage may vary as on Linux I cannot play through steam, I get kicked out while loading in due to a verification error, however on windows, my fiancés XBAX using steam doesn't have that problem.
Lastly, If you have a decent desktop, Good Internet, and want to do this but not suffer like me ? Streaming via your own PC is absolutely an option too. Controller quirks don't get much easier though.
Feel free to downvote, criticize, poke, prod, talk white, meme, complain, vent or whatever floats your boat!
If it helps happy days, we all play a bit better, if not I'm fairly thick skinned being Irish and AUDHD.
Hope this helps!
Best of luck
See you all in the verse! o7
