When combined with a G-SYNC display, the GeForce GTX 980 delivers a gaming experience that’s free of
the distracting screen tearing that currently plagues gaming when Vsync is disabled. G-SYNC also
eliminates display-subsystem-generated stutter and reduces input lag that gamers put up with today.
Utilizing DisplayPort, the GeForce GTX 980 can drive up to three G-SYNC displays in Surround.
GM2xx Maxwell also ships with an enhanced NVENC encoder that adds support for H.265 (also known
has HEVC) encoding. H.265 compression offers significant bandwidth savings versus H.264 at the same
quality level, which will help enable the next generation of streamed gaming experiences within the
home or powered by the cloud.
In addition, Maxwell’s video encoder improves H.264 video encode throughput by 2.5x over Kepler,
enabling it to encode 4K video at 60 fps. We’re supporting this feature today with ShadowPlay.
