"flickering texture on objects like baggage carts, and parked cars'
I'm sorry, but this discussion has been mixed with another problem on ground, that we don't see so, it caused by something else, and *another* problem (the small seams between tiles), which can't be fixed and it has been the same for all our sceneries.
About vehicles yes, there are a few texture for vehicles that are missing their mipmaps.
This is problem for me as was such in other post someone write they have problem to.
There wasn't just a problem report, but a solution has been posted, which was to add mipmaps and save the file back.
If you don't want to do it yourself (it's really a 2 minutes work with Imagetool), or wait for a patch, here's the files with mipmaps attached, put into the fsdreamteam\PHNL\texture folder
