volt-gui has been released in version 2.0.3.

The tool is a Vulkan implicit layer with a graphical interface that lets users adjust Vulkan behavior for games on Linux in a driver-agnostic way, covering things like texture filtering, the frame limiter, and display settings.

Version 2.0.3 is a small fix on top of 2.0.2: overly long setting descriptions were shortened, the probe failure dialog was simplified, and there was minor code cleanup in the Options tab with no functional changes.

Small Fix: 2.0.3 is a small fix over the 2.0.2 release, changing:

• Setting descriptions are shorter. Some of them had grown into paragraphs sitting under a dropdown at 9pt, which nobody reads in a settings panel. The long explanations live in the Welcome window, where you actually go to read things. Frame Limit Cadence and Depth Clamp were the worst offenders.
• The probe failure dialog is three sentences instead of a wall of text.
• Small cleanup in the Options tab code, no behaviour change.
