I have a Voodoo Banshee video card, and I have been running UT w/ no errors using a previous CVS version. Recently I updated w/ the new version from CVS and now the game randomly freezes after ~5-10 minutes. When this happens the Image on the screen simple freezes, causing a hard lockup and forcing me to reboot. No error is exported to the log. I have disabled DGA mouse. I am running Glide 2.60-13.
Try disabling the music.
Try this with 413, with either XDrv or SDLGLDrv as the render device.
