I’m guessing you are getting fuzzines due to TSR being a resolution upscaler.
It’s rebuilding the image from imperfect data.
If your ship is travelling through space it doesn’t get enough samples from previous frames to do a good job at reconstructing the image of the ship, so it probably guesses what is in the missing areas (not sure if ai is used like dlss).
The technique might just not be good for a space sim with fast moving objects.
