At least on this machine, compiling the latest version with MingW appears to completely break the frame rate. The game runs fine, but it’s chugging along with 100% of a CPU core. I have no idea what is causing this. It happens with both SDL and non-SDL versions, and regardless of optimization level. I checked the getch functions in wincurse.cpp and sdlcurse.cpp, since those are the only places calling Sleep or SDL\_Delay, and tried rearranging a few lines but I haven’t found a fix yet.

Frames do run at the normal rate with the latest downloadable Windows build (that is, ~0% CPU use when idle), and I haven’t seen this particular issue reported by anyone else, so if someone could verify it or tell me what’s going on here, I would appreciate it.

This isn’t an issue when building version 0.6, it seemingly applies only to recent versions.

Made a fix for the WinGDI (nonSDL) version [Here](https://github.com/CleverRaven/Cataclysm-DDA/pull/2304) (seeing as that issue was my fault :]).

As for the SDL version, i have no idea yet.

```
        SDL_Delay(1);

```

Maybe changing 1 to 2 will fix it. I’m not sure though, cpu usage is around 20% on my pc.
