Hardware-accelerated GPU scheduling is a Windows 10 graphics feature introduced in version H1 (2004), so it is time to evaluate its effectiveness in the face of some confusing videos and rumors.
What is a driver-based software tweak (from 451 on Nvidia or AMD 20.5.1) could be a performance improvement of between 5% and 20%, according to various reports. Such a huge display of supposed improvement that openly contradicts all logic and our calculations, deserved a little investigation to see what is real in all this. Can we get a performance as if we bought a 3080 with just one click? I think you can already imagine the answer.
The measurements were made with Windows 10 H2 (the latest October update) with Nvidia drivers 456.71 and a Pascal-based GTX 1080. The results have been taken with FCAT on Oculus CV1 and iRacing with medium-high settings where only more mirrors have been activated to force the FPS drop.
We can find this option in: Settings -> System -> Display -> Graphics Settings.
This option allows the process of representation of FPS on screen to be more compact and homogeneous, producing greater smoothness in the creation of images on screen, to translate it somehow to common language. In this way, it is not a revolution in which we will magically gain exaggerated performances, but it translates into improvements of between 0% and 1%, providing more solidity and fluidity than other types of variants.
If we go to the test numbers we will have something even more concrete:
As you can see in the results, the average frame generation time is slightly better with HAGS enabled and the improvement translates to 0.4%. It is to be expected that the results may vary depending on the configuration and the simulator used, but by the very nature of the feature none of them should be above 1%. Anyway, as always, please let us know your own experience.
See you on the track!
