Ideas
This has been noted so many times, it'd be nice if we could at least get an acknowledgement that they're working on it :/
There is a sort-of fix, add the below code to the bottom of your engine.ini file and set car reflections to ultra low.
[/script/engine.renderersettings]
r.AllowGlobalClipPlane=0
The last update seemed to break that workaround, the glitchy reflections are back in the interior views. Huzzah.
Still don't know why they don't let all players disable them (consoles included). You can play from an exterior view where they aren't ever a problem so what difference does it make? They're anti-realism, anti-immersive with how poorly done and completely broken they can be, even reflecting things hidden by the dashboard (instruments and pedals etc) in some cars and setups. Not to mention the heavy performance hit they incur.
It's beyond stupid at this point. Unless they actually go in and test and fix every single broken/wrong/impossible windscreen reflection in every car and every single time of day / lighting setup, which they'll never do, they need to get rid of them, or give us the option to get rid of them.
Absolutely no quality control here. Baffling. Even if more people complained about them they still wouldn't do anything. They clearly do not give af. Why do these stupid forums even exist?
