is there any way to bind a key to cap framerate. I need it to skip the wall in the sewer where you need to lower your framerate down to get a more consistent jump over the wall.

You should find the answer here https://docs.google.com/document/u/0/d/1mOD491U1VAA2c1VXhQB-IMLz-6oHe_cGBhF9ptqOqLo/mobilebasic

If you're using macro you don't need low fps for it. Works fine on 230 as well.
