You aren't trying to play the campaign with a debug build, are you? You need to be playing with a release build to actually run the game with smooth framerates, and most of these errors seem like the type that wouldn't occur in a release build.
Did you know that the Source Engine is developed by a large corporation of professionally paid developers, whereas the FS2Open engine is developed by a tiny group of unpaid volunteers working desperately in their spare time? I don't mean to be sarcastic - really, we'd all love to have multithreading - but it's hard.
e: Delete the Blue Planet 2 advanced graphics VP, you shouldn't be using it with Intel integrated graphics. If you want to play this campaign in full resolution with a smooth framerate I'm afraid you'll need a dedicated graphics card.
1: Even with the release build, I still had crashiness. I'll try it for the last time.
Edit: See point 3... now I feel like swallowing a bullet. However, landing in the Indus fighterbay results in a crash.
2: Yeah, like a team of 200 guys are at Valve (and according to their leaked handbook, Gabe > every other employee in the company).
3: I mistook that advice as take out the advanced GFX VP from the original Blue Planet folder (if you meant take out ALL Advanced GFX VPs in my FS2Open directory, then I wouldn't be here being an itchy bastard). I mainly play on 16:9, in 1280x600 (black bar effects, cinematic-ish, not having the screen stretch out and eating my processor power). Now I need to find another twelve hundred bucks for a dedicated tower short of begging the mob.
There was one small point I'd like to present: When I scratched out the Advanced GFX MediaVP from my FS2 MediaVP folder, I was playing the mission "Ken," and a big fraction of the Earth background was missing (mainly, the dark, lighted background), along with the scary special effects. It only happened for that mission.
Cripes, I'm asking for an ejection notice.
In space, no one can hear me rant.
