okayyy....the second build has three...standard, debug...and..."_o". Wth is the O one? And I know you said not to access the Lab, but I forgot how to in the first place...
EDIT: Nevermind...
EDIT 2: I'm having major sound issues that I didn't have in your March 6 beta build. These sound issues basically are that the sounds simply stop working. Certain ones specifically. The background ambience and music and stuff stay audible, but all weapons shots, afterburner, etc, all become silent after flying a bit ingame. Ambient ship noises are the same as usual, I still hear engines. But warps, shots, etc, even menus, all silent.
EDIT 3: I had to override the ZPack's HTL Perseus with the Original FS2 one because selecting it in the tech room was crashing the game. This also applies to the Glowpointed HTL Perseus. Don't think however it's just this build --- I've had problems with that model since the day I installed it. I agree with the assessment someone made somewhere that the HTL Perseus has something seriously wrong with it.
EDIT IV: (LOL) About the audio. It indeed does suddenly stop working partway through a mission. Everything goes dead silent. Cockpit on HTL Hercules does not show properly; eyelevel too high and the hud center reticle on it is opaque rather than transparent. ATI Radeon 9800 Pro, OpenGL mode (boycotting Direct3D until shinemapping fixed in it), Omega drivers.
EDIT V: I'm getting random crashes on various missions. NTDLL causes problems in Mystery of the Trinity, for example. Won't even load -- gets to about 40% before saying "kthxbai". This actually was a recurring problem long before this build including latest CVS changes (In other words, I think someone out there borked the CVS code).
