Wine 11.21 Speeds Up WoW64 OpenGL and Fixes Skyrim, BioShock 2 Remastered Crashes

The Wine project released development version 11.21 on October 30. Wine is the compatibility layer that runs Windows software on Linux and macOS, and it’s the foundation Valve’s Proton is built on.

What’s new

According to the official release announcement, the headline changes are:

• Better WoW64 OpenGL performance using the map_buffer_client_pointer extension. WoW64 is how Wine runs 32-bit Windows programs on a 64-bit-only setup.
• An initial version of the Voice Capture DSP library.
• Improved support for user accounts.
• Various bug fixes.

Games and apps fixed

The release closes 20 bug reports. Game and app fixes include:

• Skyrim (2011) crashing with an unhandled raw input flags error on Wine 11.11 and later, plus an assertion failure in Skyrim Special Edition.
• BioShock 2 Remastered crashing when applying display settings.
• Cinebench 2026 crashing on an unimplemented Direct3D 12 function.
• Fate/stay night REMASTERED showing only a black screen when using EGL.
• FL Studio 26.1.5 failing to start because of a signature verification problem.
• No music in Tron 2.0 and No One Lives Forever 2.
• World of Tanks not registering some keys, such as Enter and Delete, in chat.
• Zeus: Master of Olympus reporting an access violation on exit.
• I Love Science! failing to detect its CD.

Other fixes address Shift+Ctrl+Tab handling, SSL certificates that use IP address names, long HTTP response headers being cut off in winhttp, a .NET Framework 4.8 rounding error, and a crash in Wine 11.20 builds.
