1.3 — Performance, audio, graphics and interpolation improvements

1.3 installation hotfix: Ninja (ninja.exe) is now explicitly listed as a prerequisite, with installation steps and a clearer missing-tool message. Download the updated Installation.zip if setup reported missing Ninja. Install C++ CMake tools for Windows through Visual Studio Installer → Modify, or download ninja-win.zip from the official Ninja releases and add its extracted folder to Path.

Reinstall when upgrading to 1.3. The build now uses LLVM/Clang and LLD. Install LLVM 22.1 or newer, download the new Installation.zip, extract it into your existing source folder, and run Build.cmd again. Back up data/user beside b2.exe first. Rebuilding in the existing folder preserves settings and saves; a new-folder installation can restore that save folder after building. Visual Studio and the Windows SDK are still required.

Keep V-sync disabled for now. It has known issues in this release. New installations default to V-sync off; existing saved settings retain their value, so check Graphics after upgrading.

• Faster gameplay and more consistent frame times through game-code, graphics and audio improvements.
• Fixed overly-loud engine sounds.
• Fixed stale graphics resources that could cause incorrect textures and growing memory use after extended play.
• Sharper frame interpolation with fewer distorted moving edges and steadier text. Some artifacts remain on fine details and transparent overlays.
• Native Widescreen (16:9) support.
• Faster compilation and linking with the new compiler.
