How to reproduce:
1. Open the user-attached project “hdrp_dlss_ultra_performance_bugreport”

3. On the “Main Camera” GameObject set DLSS Mode to “Maximum Performance”
4. Open Window → Analysis → Profiler and leave only the “Rendering” field enabled under the “CPU Usage” field
5. Enter the Play Mode and observe the framerate in the Profiler
6. Switch DLSS Mode to “Ultra Performance”
7. Observe the framerate in the Profiler
Expected result: The framerate in “Ultra Performance” mode is higher than in “Maximum Performance” mode
Actual result: The framerate in “Ultra Performance” is significantly lower than in any other DLSS mode
