1050 TI or 1060 just isn't enough for 2042
A topic relating the recommended minimum stats is that DICE recommends the minimum GPU as being a GTX 1050 TI. I have a GTX 1060 SC 6GB (Paired with a Ryzen 5 5600X at 4.3GHz), and I can hardly breach 40 FPS on low graphics at 1080p. I locked my FPS to 30 to keep my visual performance at a smooth, constant rate. One of my other friends has a GTX 1070, and even he had FPS problems. I personally think the minimum GPU should be raised from the 1050 TI to the GTX 1080 TI, or maybe even the GTX 1660 TI. Perhaps the 1060 worked fine in the alpha, and from videos I've seen, that is the case, but with the much improved beta, it's just not powerful enough.
P.S.: No my card is not thermal throttling or being underclocked. It's at a constant 2050MHz while remaining under 70C.
What you experienced is an older version of the game. General release (and subsequent) will very likely have marked improvement in graphics.
