Mobile G-Sync works on laptops without hardware module

PC Perspective reports NVIDIA is working on a mobile version of its G-Sync technology. A leaked alpha driver already provides a showcase of the technology and NVIDIA confirmed OEMs are in the process of validating and troubleshooting the technology. Interestingly, G-Sync on laptops will not require a G-Sync module but NVIDIA mentions that there will be experience differences between the desktop and mobile version of its G-Sync technology.

While NVIDIA confirmed that G-Sync on mobile is coming in the near future, it wasn't able to discuss timing specifics or technology specifics. But because we were clearly able to get most of the positive experiences of a G-Sync monitor on a notebook that not only is not G-Sync branded, but also does not have a G-Sync module in it, questions are going to fly around the community. 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.

This leads to the question of the need for a dedicated G-Sync module on desktop screens and it seems NVIDIA hasn't 100% decided yet:

Interestingly, NVIDIA says that the answer hasn't been 100% decided yet - the future could include this same module, a new module or perhaps even no module at all. There are features and technologies in the G-Sync module that haven't been revealed, at least according to NVIDIA, and with that line of thinking I don't see a time when NVIDIA relieves the desktop market of that requirement in the near term.
