1 & 2) I ran Star Trek Online using DX11 mode, that much more resource intensive then LFS, and there was no crash for double the time frame it takes to happen in LFS. So it appears to open happen with LFS, and it started happen immediately after updating my display drivers and LFS to B14. I don't know if it's the display drivers or LFS, but considering that the display drivers work with STO, I'm gonna have to pin this on LFS for now.
3 & 4) LFS is in full screen mode, the first crash happened seconds after connecting to a server, the second crash happened after about 15 minutes and one lap into the second race I had on cargame's server.
5) I can't reliably reproduce the bug, yet. But if I can, I'll be sure to give you as much information as I can.
When Watson dumps memory, it dumps the whole system memory on a full system crash. That's if I recall correctly, that is. I am fairly sure that I'm not using a Page File, because it's really bad for the SSD's lifespan that I'm using as my system drive, so I'm pretty sure that's the first thing that I disable. (I'm not at my computer right now to confirm that.)
