Consistent framerate drops in 7.0

[hchoi405]

I'm experiencing consistent framerate drops in version 7.0 for path tracing, which are not present in previous versions (5.2, 6.0).

Here is the plot of some GPU metrics (RTX 4090) profiled using NVIDIA Frameview:

I checked several things as follows:

1. Checked CPU utilization (less than 10%).
2. Changed GPU driver version (to both the latest and slightly older versions).
3. Changed OS (tested on Windows 11 and 10).

Unfortunately, none of these solutions has solved the problem.

Is there anyone else who's experiencing the same issue?
