Upodated yesterday and now no there is no oil paint filter! Open Cl and oil paint both greyed out!

Whats the go, I updated to the latest photoshop 20.0.10 yesterday 7 August 2010, and now I have no oil paint filter! I am an illustrator an use this filter heavily. I looked on google and found that adobe photoshop no longer supporting certain graphics cards. I have a 2020 imac with the fastest and biggest equipment maxed out with 64 gigs of ram at a huge cost. Fortunatly I didnt update 2018 and 2019 photoshop and still have them as spares in my hard drive, so I can get it there but its just a pain to waste time re orgaanising all my files and brushes. Now I am afraid to do any more updates as its just dum to do so when there is a high likley hood thet the product has gone backward rather than forward!  Please let me know if oil paint is being discontinued so I can be careful not to update photoshop.
