Hey, just wanted to share my current settings for MAME after completing my upgrade of the ASUS VG248QE LCD with the NVidia DIY kit. I posted similar information in the GroovyMAME section.
It really is amazing to run nearly any emulator, including MAME, and never see a bit of tearing. I can even use Nestopia and ZSNES without any sync or tearing issues. To my understanding, the G-Sync technology is NVidia's attempt to control the software and hardware to prevent the causes of vertical tearing. Granted, this does mean you need to use the NVidia hardware along the chain, including DisplayPort connection. There is also a Ultra Low Motion Blur (ULMB) mode, which I haven't tried yet. This reminds me of a newer version of LightBoost, which dims the screen but provides a more CRT-like experience.
