Desktop Steam and Steam Deck Client Beta updates with new launch options UI

Valve has replaced another old part of Steam in the latest Desktop and Steam Deck Client Beta, with a new UI for games that have launch options set.

Currently, if you go to launch a game that has options to pick that can be anything developers set like graphics APIs, VR or not VR, modded or unmodded and so on you get this:

Now, instead, you get a nicer looking list and you can set that as the default so you're not asked every single time you launch. Very useful.

If you do want to change it after, you can just go into the game's properties and tweak it to something else or make it ask you every time again:

For the Steam Deck, this change is currently only for the desktop mode client as they haven't yet added it to Gaming Mode.

Full patch notes for the Steam Deck Client Beta:

General

• Further optimizations to load times for users with large game libraries.
• Fixed a case where the UI would think that a game is running when it's not, leaving games in an "exiting forever' state.
• Fixed a case where disconnecting a controller while navigating would not cancel repeating movements.

Desktop Mode

• Replaced launch option dialog with new UI that includes a checkbox to remember the user's selection. Added a dropdown in game properties to change that selection after it is remembered.

• Fixed intermittent browser crash when closing Update news dialog.
• Fixed a rare crash exiting New Big Picture Mode.
• Use the New Big Picture Mode standalone keyboard if Steam is configured to run in new BPM (e.g. -newbigpicture was specified on the command-line).
• Fix some UI scaling issues in the New Big Picture Mode overlay when running in games in high resolution.
