MangoHud performance overlay for Linux gets a first v0.8.2 release candidate

The popular MangoHud performance display for Linux has a new release coming that's now ready for testing, with v0.8.2-rc1 now up. It will include a bunch of bug fixes, along with a few new features and some new parameters you can use to display different things on your HUD. Be sure to check out my guide on how to use it.

As a reminder, this is what MangoHud looks like in-game (the bar on the top):

One useful new addition in the Parameters is the new work in progress "dx_api", which attempts to show the underlying DirectX API being used (for running Windows games with Wine / Proton). Plus more font size customization, support for new hardware and more.

From the changelog:

Fixes

• LLVMPIPE crash where mangohud would check vsync status.
• X11 crash when $DISPLAY was not set.
• ImGuI content width was incorrectly calculated in some cases.

• XNVCTRL was not working without nvml.
• Adressed multiple cases where the mangohud would crash on close.
• Keybinds were not working in some cases on wayland.
• Large scale fixes on OpenGL. Missing hud, flickering hud, games not starting and more.
