Techspot has performed testing on FreeSync monitors and NVIDIA GPUs to determine how well do they work together. After explaining the 4 tiers of adaptive sync support that NVIDIA has, Techspot ended up testing 7 different monitors that didn't have NVIDIA certification. All worked except for one monitor that required FreeSync over HDMI. NVIDIA currently doesn't support FreeSync over HDMI as it has tied its G-SYNC technology to Displayport only. Owners of high end FreeSync televisions are left out in the cold for now as most TVs only have HDMI connections. Everything worked perfectly fine and without issues just as they predicted. NVIDIA even supports low framerate compensation (LFC) and HDR with adaptive sync support on FreeSync monitors. They haven't tested the exclusive FreeSync 2 AMD features on NVIDIA GPUs, but they expect the basic FreeSync and HDR on those to work just fine also.
