Roblox

What works

The game itself runs nicely, light to medium games runs fine. Heavier games might have some frame drops and performance degradations issues. But generally, the game runs just fine

What does not

1. Mouse getting stuck, this happens when you right click on a game or if a game grabs your mouse. 

2. Frame drops, although it has been rarer in Wine version 6.20. It still occurs here and there

3. Very bad performance degradation, for a light game like Boost Vector, this works fine and you won't notice the performance degradation until 3-4+ hours of playing, especially if you cap the fps at 60. But for games like Arsenal or Phantom Forces, just 20-30 minutes you can already feel the framerate constantly spikes and fps keeps dipping. Keep in mind, that performance degradation depends on your hardware too

4. Some people may have texture corruption in Player or Studio

5. DXVK causes Studio to render black windows and crashes Studio sometimes

Workarounds

1. Mouse getting stuck can be resolved with a patched Wine, the patch is on https://github.com/Frogging-Fa..., which can be applied to Staging Wine

2. Frame drops can be minimized with using a different renderer, such as OpenGL, and Vulkan. DXVK can be used as well

3. This problem can be minimized with the method above. But, this one is more noticeable and is inevitable for low to mid hardware

4. This can be resolved by using DXVK or other renderer

5. Uninstall DXVK or use another wineprefix without DXVK

What was not tested

Since Roblox is a huge platform, many games are not tested. But generally, games should work fine. It is rather rare for someone to have a very specific problem, but even then it can be solved by changing simple settings such as the renderer

Hardware tested

Graphics:

• GPU: AMD
• Driver: open source

Additional Comments

Note that my experience heavily involves Grapejuice, which is a wrapper and a tool to manage Roblox on Linux. I recommend you to install this and join the Grapejuice discord server for more support

Wrappers such as Grapejuice and Roblox Linux Wrapper make installing and running Roblox much easier.

Both projects have an installation guide on their pages.
