Your system information

• System information from steam (Steam -> Help -> System Information) in a gist: up to date Archlinux. Kernel 6.6.10. AMD RX 5700 XT. Mesa 23.3.3
• Have you checked for system updates?: [Yes]
• Are you using the latest stable video driver available for your system? [Yes]
• Have you verified the game files?: [Yes]

Please describe your issue in as much detail as possible:

In Options / Video : "Dashboard maximum frames per second" has been broken (inactive) for months. I hope it will be back someday.

Steps for reproducing this issue:

1. Open Dota2
2. In Options / Video, set "Dashboard maximum frames per second" to 60
3. Despite that, GPU goes crazy, trying to push unlimited fps

Workaround : as soon as you start Dota2, go watch a live game. Fortunately, the other setting ("Maximum fps allowed") still works in-game.

Thanks for your fix.
