Framerate low when playing normally, but increases when contracts window or engineering report open

[ExEvolution]

Yeah so basically the game is running slowly in just about every situation, but as soon as I open the contracts window or the engineering report in the VAB, it jumps up to around 30-50, up from around 10

Does anyone have any idea what could be causing this?

It is a modded install of course

When I have the contracts window open, the MET is green, but when I close it, it turns back to yellow, showing that physics is lagging behind

This is Windows 32 bit on Windows 8.1 x64

Turns out its the Wider Contracts App mod causing the low FPS
