question about the App Latency

[edisonchan]

I ran some test with frameview and capframex,
The test results below are from Frameview(RT Max DLSS Perf FG Enabled and RT Max DLSS Off ):

I found that PCLatency(50ms) is very different compared to AppLatency(13ms) when DLSS was enabled:

According to the explanation on the following page, AppLatency should be very close to PCLatency, why is there such a big difference?

Nvidias Frameview is currently the only reliable way of getting latency when using DLSS 3 FG
