Hello everyone,

Just wanted to let you know we just released the FAQ for our Project FreeSync; click here to view it.

Please, feel free to post any other question(s) you may have about FreeSync and we’ll make sure to update the FAQ accordingly.

Regarding the section on differences between G-sync and freesync:
http://support.amd.com/en-us/search/faq/220

Are you saying there is a two-way hand shake with G-sync or are you just comparing the adaptive sync technologies to conventional monitors with static refresh rates?


Also, on this same page, it states there is no proprietary hardware necessary to run Freesync. Does this mean all future monitors will be Freesync capable? Is there no processing unit that must be installed on the monitor itself to enable freesync? Or does it just happen over the displayPort cable?

Additionally, if no proprietary hardware is necessary to run Freesync, then why does the following page indicate that you need a compatible AMD Radeon GPU?:
http://support.amd.com/en-us/search/faq/216

Is there any plan for Nvidia to also incorporate this technology in the future or are we looking again at two (and what may as well be considered proprietary) competing products?

---UPDATED with another question---

Is there any plan for future Intel and AMD CPUs with integrated GPUs to be FreeSync capable?

Hello ubercake,

Great questions...below are the answers :) :

1. It is our understanding that G-Sync does require a two-way handshake with each frame. This is to ensure that a frame presentation does not fall outside of the boundaries supported by the display. We eliminate that handshake by instead communicating the boundaries when a display is connected.

2. While we do not require proprietary hardware (like NVIDIA’s G-Sync monitor module), this does not mean every monitor will automatically support FreeSync in the future. Monitor vendors must implement firmware that is compatible with the DisplayPort Adaptive-Sync specification, and select a panel that is robust enough to accommodate a wide range of refresh rates. But what FreeSync enables, as an ecosystem, is the ability to implement these features quite inexpensively, and with no licensing fees to do so.

3. “Proprietary hardware” refers to the requirement for custom hardware in the monitor. Many of today’s DisplayPort 1.2-ready scalers would be compatible when combined with a robust LCD panel and the right firmware. We do not have any expectation that monitor vendors will simply provide free firmware upgrades, but we do know that the monitor technology being manufactured today is already compatible with DisplayPort Adaptive-Sync and, by extension, FreeSync.

4. We would be delighted if NVIDIA elected to support the industry-standard DisplayPort Adaptive-Sync specification. We think gamers and monitor makers would all benefit with a less expensive and licensing-free solution to dynamic refresh rates.

Let me know if you have any more questions
