I think it should work for those specs. I'm able to run it without problems on my 1650 gtx and ryzen 5 4600h. What point it occurs? Contract map and if on map which ones?
It happens on every map and contract — Mei's House, Asylum, Sunrays Apartments, Void... all environments. The FPS always starts out high, but over time it keeps dropping. However, if I'm in a contract and go back to the van to finish it, when I return to Mei's House, the FPS goes back to normal.
