No that was the tail end of any major AAA support. Before that it was better. To use 2011 as an illustration, we got…
Portal 2, Valve's last major game developed unless we count Alyx.
Witcher 2, a major PC exclusive at the time.
Skyrim, a teat still being milked
SW The Old Republic, one of EA's most expensive flops
Total War Shogun 2, the last game from Creative Assembly that was actually balanced
I think it's a symptom of the wider problems in the AAA space, more than a specific snubbing of PC gaming
There's too many devs involved and so much waste and mismanagement that focusing on any kind of optimisation is almost impossible, and what can be done is easier on a locked hardware console SKU than the myriad of different PC component combinations that are in common use.
Even then, there's so many console variants these days, especially with games still getting last gen ports, that even optimisation there is a joke compared to what it used to be.
You used to expect devs to show significant improvements after a few years in what they could get out of a console, as they learnt the tools and hardware's capabilities and got more out of them, more efficiently.
Now we're seeing games regularly getting released that barely work on the XSS, or that struggle to maintain HD resolutions on the PS5, when even just last gen it was unusual to have a PS4 game run sub 1080p, with barley worse looking graphics.
AAA is just a shit show no matter what you play on.
