@azdanov Thanks for moving the thread! 
Really “Epic” 
Well, it’s out! The new UT2004 patch adds an SDL3 client for Linux and MacOS as well as a new OpenGL renderer called AntiDrv and the old OpenGLDrv has seen some tweaks too. The AntiDrv fixes some erratic texture clipping (flickering) I saw with the old OpenGLDrv when watching the UT2004 intro video, but still has some issues with shadows not showing up properly in some situations (UT2003 intro movie).
Still lots of little bugs, but most can be worked around by tweaking settings within the UT2004.ini.
The main menu now has higher resolution assets and looks crisper than the original, although many other 2D assets are still low resolution. UT2003 still remains the better game and has a way better user interface, but I’ll take it.
