Q: How are DisplayPort™ Adaptive-Sync and Project FreeSync different? A: DisplayPort™ Adaptive-Sync is an ingredient DisplayPort™ feature that enables real-time adjustment of monitor refresh rates required by technologies like Project FreeSync. Project FreeSync is a unique AMD hardware/software solution that utilizes DisplayPort™ Adaptive-Sync protocols to enable user-facing benefits: smooth, tearing-free and low-latency gameplay and video. Q: When can I buy a monitor compatible with Project FreeSync? A: AMD has undertaken every necessary effort to enable Project FreeSync in the display ecosystem. Monitor vendors are now integrating the DisplayPort™ Adaptive-Sync specification and productizing compatible displays. AMD is working closely with these vendors to bring products to market, and we expect compatible monitors within 6-12 months. Q: What is the supported range of refresh rates with FreeSync and DisplayPort™ Adaptive-Sync? A: AMD Radeon™ graphics cards will support a wide variety of dynamic refresh ranges with Project FreeSync. Using DisplayPort™ Adaptive-Sync, the graphics card can detect and set an appropriate maximum and minimum refresh rate based on the capabilities reported by the display. Potential ranges include 36-240Hz, 21-144Hz, 17-120Hz and 9-60Hz. Q: What AMD Radeon™ GPUs are compatible with Project FreeSync? A: The first discrete GPUs compatible with Project FreeSync are the AMD Radeon™ R9 290X, R9 290, R7 260X and R7 260 graphics cards. Project FreeSync is also compatible with AMD APUs codenamed “Kabini,” “Temash,” “Beema,” and “Mullins.” All compatible products must be connected via DisplayPort™ to a display that supports DisplayPort™ Adaptive-Sync.
Hmm guess I no longer feel torn about choosing Mantle over G-Sync back when I was making a GPU decision. Now I'll essentially get both!
