Well this is a new one for me. I used to always have several instances of DF on my computer at once, each with different mods and such installed. Since I got this new laptop a few months ago, however, I've been too busy to play much and had only one install going (the latest version of course). But I just tried to get a second install going for a mod and it won't work.
I've tried installing in nested directories, completely separate directories, etc. I've tried a few different versions. I've tried hiding the original install. Nothing works.
What happens is that the new install gives me 0 FPS, jumping up to 4-6 FPS whenever I hit a button. It's completely unplayable by any standard. The original install works fine, just like always. I get my 100 or so FPS on all but crowded forts.
Has anyone else had this problem? It's like my computer knows I already have DF installed somewhere and it doesn't want me to have a second copy to play with. I don't try to run them at the same time or anything, and I've even tried closing everything down, rebooting the computer, and unzipping and running the new instance of DF without opening anything else, and it still won't work.
I apologize if this is a known issue, but I don't get online very often where I'm currently living and don't have time to scour the forums for it. Any ideas, or should I bring this to the bugs forum?
Thanks guys!
