JonDR: I own Saints Row 2 on Steam but never played it much. I constantly had technical problems that not even the extensive fan patches seemed to be able to fix. This included having to mess about with settings relating to CPU timings. It was a whole faff that put me off and I never resolved to a playable state.
The announcement for the GOG release of SR2 says it got the "GOG treatment" including a performance patch. How is it?
Saints row 2 has a problem running on a slow and fragmented disk space,. Put in on your fastest HD, and defragment the game it, and it runs as smooth as you can imagine.
The problem of the original port was their loading system. It loads little data chunks directly from your HD. So it really matter how fast your HD is, and how fragmented.
I personal use this mod, on the steam version, that fixes the awfull car handling.

Mod works, but framerate is around the usual 25-30 fps. They have nothing changed in this version. No engine fix at all. I can live with the framerate, though. The graphiccard is not even starting to work, has 51 degrees celsius, instead of the normal 59-60 degrees.
But for that price, buy the game.
