Vulkan – Dunes:

Still using the Vulkan API, but this time the data is all for the Dunes runs I did. Remember, there was a lot more combat on the Dunes course than the other courses, and it is entirely outside, in a large open area. First up are the course graphs:

 

 

 

 

 

 

Looks like we got fewer outliers here, which is always nice to see, even though outliers are not really something to worry too much about. On to the averages:

Average Frame Time (ms) Framerate (FPS)
Run 1 5.548 180.25
Run 2 5.540 180.50
Run 3 5.479 182.53

Time to turn to the percentiles:

Percentiles 0.1% 1% 99% 99.9%
Run 1 3.929 ms (254.51 FPS) 4.173 ms (239.64 FPS) 7.732 ms (129.32 FPS) 10.013 ms (99.87 FPS)
Run 2 4.178 ms (239.33 FPS) 4.331 ms (230.89 FPS) 7.492 ms (133.47 FPS) 10.440 ms (95.78 FPS)
Run 3 3.807 ms (262.69 FPS) 4.107 ms (243.49 FPS) 7.546 ms (132.53 FPS) 10.071 ms (99.30 FPS)

Looking at just the 1% to 99% data we see the game kept between about 130 FPS and 230 FPS. Only the 99.9% data dropped below triple digits on the framerate here, so it is outliers that were that slow.
Of course dropping to 60 FPS or below it would count as outliers for these runs, but to keep in practice, here are those percentiles:
 

  16.667 ms / 60 FPS
Run 1 0.001849249%
Run 2 0.001846552%
Run 3 0.003653101%

I am not sure why the third run dropped below 60 FPS twice as often as the first or second run, but considering we are at thousandths of a percent, it really does not matter much. Now for the QQ plots:


Now for the percentiles for the difference data:

Diff Percentiles 0.1% 1% 99% 99.9%
Run 1 -3.375852 ms -1.127000 ms 1.151260 ms 4.071408 ms
Run 2 -3.930001 ms -1.171470 ms 1.168470 ms 4.738990 ms
Run 3 -3.67608 ms -1.13400 ms 1.15500 ms 4.22981 ms

Still keeping pretty close to the same frame time here, which is good to see. Time for the frequency plots:

 

 

 

 

As v-sync is still turned off, the display time graphs continue to share a similar appear to the frame time graphs above:
