Here is a comparison between the .11 & .12 builds of my Newark to Kennedy test flight. Overall, the average FPS for the flight was almost the same, but the “spikes” in the .12 build (shown later) are inflating the .12 build result. If one removes all FPS over 30 ( i.e. “spikes”) from both builds, then the average FPS comparison becomes:
| Build | .11 | .12 |
|---|---|---|
| With Spikes | 19.4 | 19.8 |
| Without Spikes | 19.4 | 18.3 |
My impression during the .12 flight was that there was a slight drop in FPS compared to the .11 build, particularly during take-off & landing, and that was confirmed when I compared the screenshots with the dev-mode FPS enabled:
| Build | .11 | .12 |
|---|---|---|
| Spawn | 20.9 | 19.5 |
| Take off | 18.5 | 17.1 |
| On Final | 20.4 | 15.9 |
| Landing | 15.1 | 12.7 |
| Parked | 14.4 | 13.8 |
Although I was flying along the same flight plan, the two flights were obviously not identical - altitudes varied, where I looked varied, my speed varied, I did not take-off or land at exactly the same time, etc., so the exact numbers are not so important as the trend - the .12 build FPS is less across the board.
I also thought that the flight was not as smooth as the .11 build. Comparing the data collected using HWinfo64 shows:
The .12 build shows “spikes” that were not present on the .11 build. These spikes might be the cause of my subjective impression of “less-smoothness”. Note that these spikes are not causing noticeable stutters, such as those I see when AI traffic & airport scenery is loaded.
I also took a flight around the San Fransisco Bay area last night (on .11) and today (on .12) and although I did not collect any data, my impression of today’s .12 build flight was that it too was less smooth.
Next, looking at Physical Memory Load, you can see what may be the result of the memory Optimizations in the .12 build:
So, it looks like the optimizations may help those with less RAM on the motherboard, but on my PC it has had a slight, but noticeable, negative effect on performance.
