I suppose it would be possible to fix the issue highlighted here in the same way:

Street directions are visible further than they should in Hardware mode at higher resolutions

where basically these yellow arrows that are used to outline the edges of the track always end up using their highest resolution mip map, but the intensity (alpha transparency) of the arrow changes as mip maps get higher resolution, so when playing at a higher output resolution (with the HW renderer) you always see them from a distance, even if you were not supposed to.
I suppose there's a way to find their texture hash and force them to use the original mip map they would have used at each camera distance?
Sorry, I'm new to pcsx2.

Burnout 3 has had mipmapping automatically for almost 2 years now.

So does that mean that issue is now fixed in HW rendering mode?
