Untolerably Slow Debug

[Oracular]

The framerate on my debug is just absurdly low. I'm porting my XNA game to SFML. In XNA, I had framerates well over 300, and now everything is choppy and I cannot even debug the game on debug because it behaves totally different due to the speed. Why is this, and what can I do to avoid this issue?

We don't know what's inside your code, and you don't know what is slowing it down. So we're already kind of stuck. You should really profile your application.

Are you inadvertently copying large objects? When I ported my game from C#/XNA to C++/SFML, I had similar issues because I was unfamiliar with C++.
