MrBoat: Here's a good way to learn how Inspector works:

C:\ProgramData\GOG.com\Galaxy\support\1430740458\1430740458\add\NVI
Click on the button that's next to the Driver Version, put Saints Row 2 on the search filter, go to the bottom and you'll find "Frame Rate Limiter" highlighted. Click on the right button to change it to it's default setting or just select "PS_FRAMERATE_LIMITER_DISABLED".
Once again... A very bad move, GOG. Change your installation script as soon as possible. If people run into problems give this "fix" for them separately.
Alarion: The game is somewhat choppy for me when driving vehicles on hight speed. I wanted to change the frame cap, to maybe fix that issue. However, in my Galaxy folder there is no support folder, and a search for "NVI" didn't turn up anyhting either (also not in the game installation folder, too).
Any idea where I can find the files to do the framerate uncap?
Search in your game directory and subfolders for the program nvidiainspector.exe. Start it and remove the added saints row 2 profile.
