Wine 11.21 Ships With Faster WoW64 OpenGL for Older Games
The biweekly development build also adds a first version of the Voice Capture DSP library and fixes World of Tanks chat keys, Skyrim crashes and BioShock 2 Remastered display settings.
The Wine project released Wine 11.21 on October 31, 2026, a biweekly development build of the compatibility layer used to run Windows applications and games on Linux, according to gamingonlinux.com.
The headline change is improved WoW64 OpenGL performance, delivered through the map_buffer_client_pointer extension. According to the project's notes, the change is intended to help older 32-bit Windows games that use OpenGL run better through Wine, provided the graphics driver supports the extension.
Wine 11.21 also introduces an initial version of the Voice Capture DSP library and improves support for user accounts.
Bug fixes
The build carries a batch of fixes, including World of Tanks chat keys, rawinput crashes in Skyrim and display settings in BioShock 2 Remastered. It also addresses a regression in which Wine 11.20 compiled but produced a segmentation fault.
The Skyrim fix follows a problem seen in Wine 11.11 and later, where the 2011 game crashed because of unhandled rawinput flags.
