Since upgrading to RTX 5000 from 3000, I've noticed that whenever there is reflection on screen (not SSR, but real mirror reflections), primary depth buffer will be correct for exactly one frame, then replaced by the depth buffer of the reflection. Replaced as in the same clear operation. In fact there is only one clear with matching resolution and high draw calls, as opposed to like 4 when I ran with RTX 3000.
I heard about a hardware-level depth buffer optimization introduced by Nvidia with Blackwell, which sounds very much like the cause of this. If this is the case, I find it very strange that such a guaranteed problem with practically no fix has precisely zero discussion online.
Can anyone verify?
