Hi,if you are unable to start NS2 via Proton (right click at Library entry -> Properties -> check Force the use of a specific steam play compatibility tool -> select latest version of proton) please confirm that your system is compatible to dxvk (see https://github.com/lutris/lutris/wiki/How-to:-DXVK If that's the case and NS2 still doesn't start please create a new thread in the tech support section:So far we are aware of the following issues with Proton:1) Black graphic artifacts with TAA enable2) Crash reporter crashes when you close the application3) Enabling multithreaded physics hangs the application on startup4) Starting a listen server (e.g. Tutorial) crashes the application5) NS2 stays black after connecting to a server when application window is not focused during loadingWe have a fix ready for 1, a workaround for 2 and 3, are investigating 4-5. If you notice any further issues please let us know.Additionally I understand that some are frustrated about us ending support for the native Linux client. But our Linux support has been lacking for the last 5 years due to a lack of budget and a dedicated Linux client developer. New engine features were not ported to Linux, only the most critical issues were fixed and performance decreased with every new update. We mostly only worked specifically on the Linux server.From our point of view that was not acceptable but we kept the native Linux client around because there was no real alternative for our Linux users, who are very valuable members of the NS2 community.Now with the recent development of Proton (or more precisely dxvk and wine) we just felt like it's the better option to focus our limited development resources on that for an acceptable NS2 experience for our Linux users instead of "dragging" the native client along.We are also looking for more Linux users as volunteer play testers to ensure NS2 experience with proton is as pleasant as possible.
