[Runtime Bug]:Freedom Fighters Steam – Main Camera flickers between defined and undefined, causing world instability and broken volumetrics

Describe the bug

In Freedom Fighters (Steam), the main camera appears to rapidly switch between a defined state and "Unknown Camera" during gameplay.

This results in:

World instability (flickering in/out)

Volumetric fog disappearing after camera movement

Dust Particles not rendering or behaving incorrectly

Certain alpha textures detaching/moving incorrectly when the camera is in motion

How do you reproduce the bug?

Launch Freedom Fighters (Steam) with RTX Remix runtime.

Load the Police Station map (or any map).

Observe volumetric fog — it appears briefly, then disappears after moving the camera.

Open Dev Settings → Camera → Types in Remix menus — note that the camera type switches between defined and "Unknown Camera".

While in motion, observe that when the camera renders a character, the world becomes unstable/wobbly, but when no character is in view, the world stabilizes.

What is the expected behavior?

RTX Remix should consistently use the correct main camera for rendering the world, maintaining stability and ensuring that volumetric and particle effects remain visible and functional.

Reproduce the issue in Freedom Fighters (Steam) using the RTX Remix runtime on the Police Station map, then inspect the Dev Settings → Camera → Types state while moving the camera. Review bridge64.log, remix-dxvk.log, bridge32.log, dxwrapper-freedom.log, and the crash dump for the camera transitions. Done means the main camera remains consistently defined and volumetric fog, particles, alpha textures, and world stability persist during movement.
