The frame time performance closely reflected what we saw in the frames per second test, as the GeForce GTX 780 was 11% slower than the GTX Titan but 24% faster than the GTX 680.
Even the GeForce GTX Titan has trouble handling Sleeping Dogs and as you can see the GTX 780 provided similar performance to the Radeon HD 7970 GHz Edition with 29.8fps and it was 11% slower than Nvidia's flagship GTX Titan. Still the GTX 780 was 34% faster than the GTX 680 which is obviously a fairly significant performance improvment.
Although the GeForce GTX 780 was 3% slower than the Radeon HD 7970 GHz Edition when comparing frames per second performance, it was able to get back on top in the frame time testing, winning by a 1% margin.
