Hi, This is a personal filter of mine which I use for when I'm racing some of the classic cars that AC has to offer. It creates that old film look of old TV's and looks great with the old style F1 cars. It works with the default weathers, however I use it with the content manager and the Good & Bad weathers mod. I set the time for around 1pm like the classic F1 start time with usually the mid clear weather. Thought I'd share it.
Just place in the folder \assettocorsa\system\cfg\ppfilters
