Ryan's Notes: Obviously we went straight to NVIDIA when we got this hardware up and running to ask the important questions: how and why? The answer starts with the upcoming release of G-Sync notebooks in the market. This driver was not "hacked" to get G-Sync enabled but was rather provided to OEMs working on G-Sync gaming notebooks to being the process of validating and troubleshooting the technology. The driver got out into the wild and the result is what you see here today: users that have hardware that is kind-of G-Sync and variable refresh capable.
Here's the facts: NVIDIA will release G-Sync on mobile devices without the requirement of a G-Sync module, but the company claims that there will be experience differences between desktop and mobile iterations of the technology. When pushed on what differences those might be, NVIDIA emphatically stated they exist but would be holding off on talking specifics until the mobile release of G-Sync when feature support is finalized.
