It's impressive. What kind of machine do you need to run it in terms of system specs?
My PC:
Intel core i5-2310 @2.90GHz - 8 GB
NVIDIA GeForce GTX 960 - 2 GB
Windows 7 Home Premium
The frame rate was fluctuating between 30 - 60fps when I was playing (I think some of the dips were video capture related).
I haven't been keeping up on cxbx. Are they still basically trying to convert the original game code to standard PC code or are they emulating the hardware?
Good question. I'm not really sure myself, just having a quick look at the CXBXR
wiki page, I think it sounds like they're trying to emulate it.
