Frame delayed when Captured in Nsight

Hey,

So I've been bashing my head against the wall trying to figure out what could be the cause of this.
Basically, whenever I take GPU captures in Nvidia Nsight, it looks like my entire frame is being delayed by several milliseconds.

Here's a picture for reference.

As you can see, my entire capture reads 29.33ms, but there's no actual work being executed until about 14ms have passed.
There's no sync events, no stalls. The SM Occupancy reads 100% idle in the empty area.
My first guess was that the capture was going from present …
