I don’t remember this happening when I had my previous Cataclysm bout. I could turn on safe mode, hold down a direction key and cover 20-30 tiles in a second.
Now this no longer works, my outdoor walks slow to a crawl when I’m in the wide open. When it’s indoors, forest or night, the speed is fine. Map scrolling also suffers from this slowdown so I assume something’s changed about the way the game draws symbols?
I play Linux console version in LXTerminal.
