Improve Graphics Capabilities

Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Is your feature request related to a problem?

From what I can tell, this port of ROBLOX is based on the android version (which makes a lot of sense considering android is based on Linux). An unfortunate side effect of this is that the Graphics settings seem to be held back. The most noticeable shortfall is antialiasing, which it either doesn't do as well as the Windows client or just doesn't do at all. While this makes sense for android devices since they don't usually have very high screen resolutions, and are often limited in their graphical processing capabilities, it really looks quite bad on desktop.

Describe the Solution you'd Like

Simply put, I am curious weather it is possible to counteract this in some form. While I am not super familiar with rendering, there are 2 ways I can think of that could be done to mitigate this:

1. Supersampling the Roblox window to a higher resolution, thus eliminating the need for antialiasing. While I don't fully understand the technical details of how Sober works, I consider this to be the easiest way to fix this issue.

Describe Alternatives you've considered

2. Somehow introduce antialiasing in between Roblox and Sober. I am still new to Linux stuff, so this may not even really be possible. But still, I do wonder if it is possible to add some form of graphics layer to whatever rending Sober uses.

Additional context

Again, I am still quite new to Linux stuff, but the open source nature of everything has been really cool to me! I'd love to help out with this in any way that I can.

I assume you're using a hidpi screen. So i'd recommend you to just right click Sober app icon and click setting then toggle on HiDPI.
Or adjust the configuration file through ~/.var/app/org.vinegarhq.Sober/config/sober/config.json :
find this line enable_hidpi and change to true, you can also add this fflag (value could be 0,1,2,4,8,16) to force msaa "FIntDebugForceMSAASamples": "2" and this graphics_optimization_mode to quality. But after all, enabling hidpi is enough i guess

While this does fix aliasing, it doesn't fix the other issues such as there being no ambient occlusion. Is there any way to fix that?

i also noticed shadows are lower quality than desktop. @wguijweguiuhwf i dont think there is a fix, as roblox on android is just compiled that way, for what i know.

After playing a few more games, I realized that roblox's water terrain is opaque instead of transparent. This too would also be a nice QOL fix.

[awesomefroggy29]

@tmwaldo1-ai it should be transparent. it is for me, so maybe it has to do with your graphics drivers?

Oh. Yeah, They're up to date... I'll submit a bug report on that.

ah that sucks, one of the main reasons why i play roblox on windows instead of linux is because the graphics are just way better on windows.

[awesomefroggy29]

@wguijweguiuhwf it really shouldn’t be that bad, from my experience the graphics are pretty decent, just slightly worse in the shadows

I switched to CatchyOS yesterday for unrelated reasons, and sure enough the water is actually clear now. Now I know it's a mint/X11 specific bug.

Hi! Im finding a way to make the water clear too, do you have any exact settings that make the water clear? I use cachyos, latest kernel and drivers, hyprland(wayland), HiDPI is allowed, no FF, and i enabled openGL instead of vulkan(perf issues). thank you!

[awesomefroggy29]

@eyehkeyer1-cpu it is very likely that it is due to OpenGL, switch to vulkan if possible. I had the same problem on my orange pi 5 with waydroid, so I switched to vulkan

IT WORKS! But i have to use 8 graphics level instead of 10, because yeah. my igpu is bad at vulkan and the graphics increased so much

Nice
