DXVK vs Sober

DXVK is a Vulkan-based translation layer for running Direct3D 8, 9, 10, and 11 applications on Linux through Wine. DXVK Native can also run without Wine and is intended for game and application ports or port bring-up. The project provides release builds and links to recent development builds through GitHub; release packages include 32-bit and 64-bit versions. Steam Play, Lutris, Bottles, and Heroic Launcher can configure DXVK automatically when enabled. An optional HUD can display frame rate, frame times, GPU load, memory use, API feature level, and shader compiler activity. On supported drivers, Graphics Pipeline Library can compile Vulkan shaders as games load Direct3D shaders, reducing or eliminating shader compilation stutter in many games. Users can configure shader caching, logging, and GPU selection through environment variables or a configuration file. DXVK is free under the zlib/libpng license and supports Linux and Windows. It requires a sufficiently recent Vulkan driver. The project warns that modifying Direct3D libraries in multiplayer games may be considered cheating and could result in an account ban.

Sober is an unofficial runtime for running Roblox on Linux desktops. It bridges the Android version of Roblox to Linux through a specialized runtime for Roblox code, and is distributed as a Flatpak through Flathub. The documented minimums are Linux kernel 5.11 or newer, an x86-64/AMD64 processor with SSE4.1 support, and graphics capable of OpenGL ES 3.0. Vulkan is supported, and OpenGL can be configured as a workaround for some graphics problems. Options include gamepad support, graphics quality, server location indicators, touchscreen mode, and Discord Rich Presence. The project says performance can match or exceed the native Windows client on the same machine. Ads and telemetry are disabled by default, according to the Flathub listing. Sober is closed source, and its developers say this is intended to reduce abuse that could lead Roblox to block it. The project describes the software as experimental, with possible bugs or instability, and it may be discontinued. It cannot run multiple Roblox instances; the FAQ points users to Vinegar for Roblox Studio.
