Unstable, flickering virtual motion vectors in Need For Speed: Underground 2

[UncleRito]

• The game has an issue where the virtual motion vectors on many objects seem to jump around randomly which causes severe visual artifacts with temporal reuse, dlss, frame generation, motion blur, among others.

• bridge #44, and dxvk remix #382 were used to test

• 4090

• Game ready driver ver 546.33

• Latest game version

Attached files! SPEED2_d3d9.log d3d9.log rtx.txt

To Reproduce Steps to reproduce the behavior:

1. Run the game with remix installed
2. start a new game to enter freeroam
3. Turn on debug mode>virtual motion vectors
4. Start driving, and notice that motion vectors for many static objects in the scene flicker in random directions.

Expected behavior

• Motion vectors should be completely stable for non-moving objects.

Screenshots Here's a video example of the problem. Notice that many static objects flicker for one frame at random times.

Yeah idk what that link at the top of the issue is. Just github being github. also rename rtx.txt to rtx.conf if you need it. Github doesn't let me upload conf files.

The issue was with unique object search distance being too high by default. I'm closing the issue now.
