    Ok so a while back the amd drivers conflicted with this games grass, It caused spiky black lines to flicker all over the screen, The fix for this was to disable grass or update to the 18.1.2 drivers, Well that issue has been gone for me for months, Have had the 19.1.2 drivers installed with no issues, Recorded multiple videos for youtube without issues. Then this game gets a patch today and the black spiky lines have returned with a vengeance. Tried rolling back 5 different drivers and none fixed it. The BeamNG devs said this is not a game bug, But this issue didn't come back until this latest patch, Its been perfect for near 3 months, I havnt made any driver changes before hand and just ran the game pre patch yesterday just fine. It is EXTREMELY frustrating as my youtube channel is based on BeamNG content, I cant disable all the grass and make the game look like its from 2002 and keep quality content :| Ive also cleared the game cache and DDU'd the drivers multiple times. so thats not the issue

    well im sure a fix will be released. Sadly I dont have that card to test myself, however i do have a 580 to test. But Im using my 1060 at the moment and i dont want to have to deal with uninstalling and reinstalling drivers etc.

    Most of the thing suggest this is not an issue coming from the game, but it's a bug introduced in some AMD drivers from around July 2018.
    This is not happening with Nvidia/Intel GPUs, but most importantly it happens only in certain AMD drivers versions (which is a strong hint for driver-related issues)

    This specific issue is created when you have your cache generated, and you are using the 'supposedly' faulty drivers in that moment.
    Since the cache is only generated after an update (or after you press 'Clear Cache'), that may explain why the issue was not occurring since then for you, and appeared back with the latest update (which again, would force a new cache).

    I'd suggest retrying the 1st solution in here:
    https://www.beamng.com/threads/0-15-discussion-thread-read-1-post.59824/

    Also warmly recommended to report this to AMD (via their forum/support/etc.)
