Hello everyone, I'm currently trying to force v-sync in the game Sonic Generations since the in-game v-sync is horrible. I'm trying to do this on a laptop with Optimus, so using the nVidia Experience "V-sync On" is not possible and my only option is D3Doverrider. The Overrider works on many other games, but not in generations. I tried it on Win 7, 8.1 and 10. It should work, however, since it works for other people, and it has worked for me in the past. I've tried several suggestions like changing compatibility settings, but it didn't help. So what I'd like to know is: What is the cause of the Overrider working for one user but not another when the operating system is the same and the game/executable is the same? And is there a way to make it work? Thank you!
