Most lightweight X DEs or window managers like awesome in Linux don’t make any attempt to implement vsync, it’s up to you to use another standalone compositor to enable it, usually compton. If it’s not working even then it’s probably a problem with the graphics driver not the DE, and a heavyweight DE likely wouldn’t fare any better. Personally I have never been able to make nVidia cards vsync reliably and my Intel laptop is also never quite right. Only AMD with their newer driver has been perfect for me.
