Counting pixels in games with adaptive resolution is typically incredibly tedious due to the use of TXAA to smooth the image out. Because Titanfall 2 allows us to use adaptive resolutions on PC, we have the unique opportunity to read the resolution of frames directly from RAM. The width and height are displayed on the top right of the footage, polled once every 100ms. The white text is the frame rate and orange is the resolution scaler percentage relative to native resolution.

I played the game on max settings, max FoV, at 1920x1080, targeting 60fps. The resolution on average reached resolutions appropriate for 1440p and almost never dropped below 60fps for all of my testing.

Some findings:
I targeted 60 fps, but the game attempted to maintain 65 fps, I assume for smoothness during sudden drops. It offers more leeway to give the scaler time to compensate.
The resolution caps out on the high end at double width and double height (in this case, 4k). Beyond this, the frame rate will increase above the target. If supersampling is disabled, it will run at native resolution and an increased frame rate.
On the lower end, the resolution will bottom out at half internal resolution for both width and height. Beyond this, the frame rate becomes lower than the target.
