I think I’m missing something here… So I was under he impression that the temporal upsampling feature is similar to checkerboard rendering, which should allow you to get higher frame-rates with minimal loss in quality. So I thought, hey, this would be perfect to use on the MacBook where the frame-rate suffers. However, while the loss in quality is very minimal, I’m finding that the frame rate drops when I enable this feature, even at the lowest screen percentage of 50%. In the editor, this is what I’m seeing:
Temporal AA enabled @ 50% screen size: 45fps
Temporal AA enabled @ 100% screen size: 38fps ← this I expected as there is a cost to enabling the feature
Temporal AA disabled @ 100% screen size: 47fps ← this is not expected, higher fps with feature disabled and screen size @ 100%
So after this I disabled high-dpi mode as I figured that maybe it’s enabling the retina display mode for the 3D window or something that could be affecting performance, but from there I’m finding a drop from 67FPS with TAA disabled, to 50fps with TAA enabled with a screen size of 50%. In other words, I end up with a frame rate lower than simply disabling this feature and not using temporal upsampling at all.
What am I missing here? Is the feature simply a conceptual feature which isn’t actually useful in the real world yet, or is there something else I should be doing in addition to enabling temporal upsampling in the project settings and dropping my screen size to reap the benefits?
