Well... there are some things we should consider first:
1. PC gaming is always technically more impresive than console gaming, due to devs putting a good part of "optimizations" in players hands (almost unlimited hardware upgradability)
2. PC gaming is already next-gen ready like 1 or 2 years before consoles next gen, current 2080 cards will already run PS5 games at low/mid/high combinations of settings at probably 1440p fixed resolution by the rest of the generation. A lot of players went till mid gen with GTX 9xx cards with no issues at all.
3. Most PC games are console ports, if there's not something as "visually outstanding" on PC it's because it's basically running prev gen optimized games. I'm totally sure DeS will run on PC same or better with RTX 2xxx cards.
4. DeS doesn't even look THAT good, to begin with, I think it can be run by PS4 reducing assets resolution and some level of details but it would be almost identical for most people (yes, those that don't have 4K TVs like... 90% of gamers or more).
5. PC gaming is THE competitive gaming platform so exclusives are supposed to run at as many FPS as it can hold more than with more effects.
PC gaming is just another beast, PS5 isn't some miracle machine that PC can't match... current PCs are already more powerful or as much as PS5 given a budget (which will be much smaller due to new cards and components)
