http://bugs.winehq.org/show_bug.cgi?id=59241 Bug ID: 59241 Summary: [Feature-Request] Add optional environment variable to disable IPv6 in Wine Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@list.winehq.org Reporter: bugs.winehq.org.confess471@passinbox.com Distribution: --- Issue Description Some games running under Wine/Proton encounter high or unstable ping when IPv6 is available but routing is suboptimal (e.g., Overwatch 2). Currently, there is no way to disable IPv6 within Proton or Wine without changing system-wide settings. This can negatively affect gameplay, especially on Linux systems where global IPv6 deactivation is undesirable. Other applications may use or depend on IPv6. The most elegant way to handle this would be following: Proposed Solution: Introduce an optional environment variable, for example: WINE_DISABLE_IPV6=1 Benefits: Allows users to fix IPv6-related latency issues in games/applications without modifying system-wide IPv6 settings Improves Linux gaming experience for games that prefer IPv4 in poorly routed IPv6 environments References: Reddit discussion about Overwatch 2 high ping when IPv6 is enabled: https://www.reddit.com/r/overwatch2/comments/1n4a4ko Blizzard forums: users report IPv6 routing causing high ping: https://us.forums.blizzard.com/en/overwatch/t/my-ping-keep-spiking-and-rubbe...
