The worse thing, by far, with PC gaming is that too many publishers are releasing buggy and/or poorly optimised games. I buy a lot of PC games and I swear that about 8 out of 10 of them launch with issues that then means I have to wait weeks, even months, for fixes. This has got much worse in the last 3-4 years and I don't think we can blame COVID for all of it.
Shader compilation stutter is the worse offender and that usually comes hand in hand with Unreal Engine 4, an old engine that is still depressingly popular with developers and which has these issues that most of them either choose not to fix or just don't care about enough to bother. I am astounded at how many major releases are pushed out with this issue on PC. Of course, it is a non-issue on consoles due to the them having fixed hardware which means the pre-compiled shaders can be distributed with the game itself and updated via patches, something not possible on PC. This additional work that is required to get the games working on PC seems to be too much for many developers.
For example, the recent Final Fantasy VII Rebirth launched on PC and the developers even added a pre-shader compilation during the initial boot but it only creates about 70% of them meaning that the other 30% are generated as you play resulting in stuttering for a few hours. And then just when you have the game running smoothly, you find that the stutters are back because you updated your graphics drivers for a new game you just bought. You would think that Square-Enix would be concerned at one of their much-loved and renowned franchises having performance issues but it seems they just don't care. EA Sports WRC, another UE4 game, was a stuttering mess on PC that tooks months to fix.
Despite Digital Foundry highlighting issues with games such as Star Wars Jedi: Survivor (which is still an embarrassing stuttering mess on PC with RT enabled) and many, many other games, it seems like most publishers just choose to ignore them. That said, I think EA are easily the worst publisher at the moment for pushing out half broken games unless they have "FIFA/FC" or "Sims" in their names in which case they receive decent post-launch support.
PC gaming is awesome when everything works, offering a better than console experience, but it also sadly sucks when it doesn't. And, unfortunately, it seems that the well-optimised gems like Kingdom Come: Deliverance II and Indiana Jones and the Great Circle are the exception rather than rule.
