Yes, that is true, but there are several reasons for such a feature or mod: 1. It would make it easy to run comparable benchmarks on different operating systems and computers. 2. You do not have to setup external measuring tools on every system you want to bench, you can just run it everywhere where KSP runs in the first place. 3. Tools like BuGLe may slow down KSP a lot, because they measure the FPS for each frame, and write it down to a file for each frame. This can result in very different results on different systems, maybe even depending on the specific OpenGL code. 4. Also complicated tasks like building a 32-bit BuGLe on a 64-bit Linux for comparison measurements wouldn't be necessary any more.
