Yeah, I'm still using SwiftShader, and it crashes in the same places. Sometimes I'm able to load the tutorial area, but when I'm done with it and it starts loading the port, it usually crashes. Rarely, it loads and I can proceed to finish the tutorial. That's the farthest I've gotten before it crashes, but very recently (it must of been a blue moon or something) I was able to load the Oxbay cutscene and was able to do my first sea battle in about 3 years. Also, here are more of my specs
Processor: Intel(R) Core(TM) i3-2350M CPU @ 2.3 GHZ

DirectX: 11
