After Simupdate 5 are the contrails looks bad at the end. but see by you self in the picture in the attachment
MSFS2020- Steam
Version: Su 5 + hotfix
Do you have an nvidia GPU? There is an issue with the latest driver that produces similar artifacts.
no i have a amd readon 6800xt.
Yes, it looks bad when you look behind towards the end:
And i don’t think the plane end looks realistic either:
I think contrails start behind the aircraft, you don’t see them coming out of the engine. and they start very narrow and compact. Farther behind the aircraft they get more volume.
Looks very bad if you ask me:
Do you have the same issue if you follow the OP’s steps to reproduce it?
yes
Provide extra information to complete the original description of the issue:
need to zoom quite a lot to replicate and see how it ends
If relevant, provide additional screenshots/video:
