No, I was always playing at 60hz. My monitor only supports 60Hz on resolutions above 1024X768. And i haven't touched a thing on the nvidia control panel since I reinstaled Windows and updated the drives. I didn't mention this, sorry, but I only changed the ingame resolution settings, wich, like I said, did not scale in any way (had little black stripes on the top, bottom and both sides of my screen, since I was using a lower resolution than my monitor's). I was also using the game's triple-buffering settings, without frame rate lock. But I'm still using that, so I don't think it was relevant information.
