Final Words & Conclusion

In a world where anything and everything is measured and observed these days we always find it refreshing to divert from the regular benchmarks and spend some time on frame-time recordings with FCAT (and then analyze it). Often it'll back what we see on-screen, we can output that data and place it into a plot for you guys to see what is going on. As such we always add these results to try and find anomalies.
  

 
We do hope you enjoy these results as well, we also understand that they can be a tad hard to understand and grasp for the average user who just wants to play games and relate anything and everything to frame-rates. The two are intertwined though. Fact is that FCAT in the past exposed micro-stuttering issues, it exposed frame-pacing issues, it exposed game rendering issues and a with the introduction of DX12 we exposed the UWP DirectX 12 issues. That makes FCAT an excellent tool to visualize anomalies that shouldn't happen or are hard to track. 

Conclusion

FCAT frame-time measurements bring you an overview in the way how a GPU interacts relative to frame-rate, latency and anomalies. You will, however, see less issues on a single GPU setup (obviously) opposed to more complex to sync Multi-GPU setups. Multi GPU however is slowly fading out of the PC gaming spectrum. But hey, if there is a problem, rest assured it would be exposed. Comparing apples to oranges, both cards each show minor oddities here and there, it however is a too close to call difference. Overall we can say that Pascal with the GeForce GTX 1080 and the VEGA10 with the Radeon RX Vega 64 perform really well in the twelve FCAT tests we ran it through. Multiple tests were DirectX 12 enabled. All games passed our examination easily without any noticeable stutters or anomalies aside from an exception here and there. When we zoom in a bit, Nvidia had the upper hand, and AMD has some work to do with AotS and GTA-V. It's all marginal though and nothing jumps out as very worrying. You also need to consider and weigh in that the GTX 1080 has had a year to ripen its driver whereas the RX Vega 64 was just released and can expect multiple driver updates. The ground work is solid though. Any game and any title can show some game engine related stuff, but that's not what we are looking at. The nice 8 GB frame-buffers these days the GTX 1080 and Vega 64 obviously helps out significantly.
