DF FastFlags no longer reset while you play

Flags such as DFIntTaskSchedulerTargetFps used to work for about two minutes and then go back to Roblox’s value, because the game fetches its settings again while it runs (#61). Cordial now notices that refresh in the game’s own log and applies your overrides again straight after it. This covers every flag you set, from flags.json, a plugin or Settings. Set CORDIAL_NO_FLAG_REDELIVERY=1 to turn it off. The same idea was sent as a pull request by burlone0 (#73) and shaped what shipped.

​
Frame rate limit

Settings has a Frame rate limit: Display refresh (the default), 90, 120, 144, 165 or 240. It applies to a running game. Going back to Display refresh takes effect at Roblox’s next settings refresh, up to two minutes. A limit above your monitor’s refresh rate needs a monitor that fast: on a 60 Hz screen a higher limit measured worse, not better.

​
The text editor appears without working Vulkan

When there is no hardware Vulkan, Cordial now draws its window with GTK’s cairo renderer, so a focused text box shows its editor instead of a blank or grey game (#53). Setting GSK_RENDERER yourself still wins. This is not yet confirmed on the reporter’s machine.

Contributed fixes

  • No crash entering fullscreen on AMD’s RADV driver, by kaicsm (#72, for #39).
  • Pointer lock works on KDE Plasma (Wayland), so the camera turns with a right-drag or shift lock, by burlone0 (#70). Only KDE is affected.
  • Missing textures on GPUs without ETC2 support, such as studs and some materials on NVIDIA under Vulkan, are now decoded by Cordial, by burlone0 (#69). The author found and tested it on an RTX 5070; the changes made on top before merging have not run on NVIDIA yet. Set CORDIAL_NO_ETC_EMULATION=1 to turn it off.

​
Also

  • The doctor now checks NVIDIA-specific things: the driver series, whether the Flatpak’s NVIDIA extension matches your driver, and kernel modeset.
  • The Shaders and MangoHUD install hints now give the right command: the Flatpak extension’s //25.08 branch (choosing stable installs one that is never loaded, #68), or your distribution’s own package command.
  • Settings > Plugins: development plugins are listed with installed ones (marked “Development”), can be removed from Cordial’s list (the folder is kept), and turning off “Use plugins” now greys out every plugin control.
  • The Flatpak is now the recommended install.

​
What is still broken

The signed-in startup freeze is not fixed. Resizing the window does not redraw the game until you stop dragging. Movement keys sometimes stop working after joining a game (#29); respawning or re-joining brings them back. A Roblox version released only for ARM64 is not shown on x86_64 machines. Some games show the mobile (touch) interface. The rest of the list in the 0.23.0 notes still applies.
