- fixed spriteballexplosion sounds playing client side
- faster translocation effect in software mode
- fixed collision bug which cropped up in 420
- fixed D3D 32 bit zbuffer allocation
- lowered NGStats thread priority on dedicated servers, so NGStats doesn't hold up level changes.
- Added bExternalBatcher configuration option to [Engine.GameInfo]. If true, the game doesn't try to run the NGStats world log batch process.
- The 'Use32BitZBuffer' switch in the advanced Direct3D options, which is disabled by default, will force the use of a 32-bit Z buffer even in 16-bit color display modes. This can be used to fix flickering world surfaces and similar visual corruption when running in 16-bit mode on several cards, like the Matrox G400
