The Seattle museum is really amazing, i went last year. The tour guides at the museum are retired Boeing and military guys, they got a real kick out of my 14 year old's questions and knowledge of cold war era SAM systems (mostly from playin g DCS) haha.
When I visited in 2018, one of the guides was a retired astronaut. I completely failed to have a conversation with him as I was star-struck and barely managed to hold a door open for him without making a fool out of myself.
The big one I remember was many applications, not just games assuming the buffer swap was performed by a blit into the display buffer, not an framebuffer pointer update. They relied on the previous frames data still being in the back buffer. For those applications you were forced to blit the buffer, not swap the pointer and take a performance hit.
I also remember a media player being called out by name in the code for doing invalid operations, needing a work around and code to detect it was running just to function.
