gamerk316 :
These are 2 examples of console ports which have been in the PC media and extended tech media for being VERY poorly optimized on PC and causing various problems, even at the top end of the Gfx spectrum.
I'm going to call this out. Depending on perspective, the game is actually VERY well optimized.

Extraordinarily CPU agnostic. Open world titles tend to be very CPU dependent (See: Skyrim), so CDPR did a very good job letting their title run on pretty much any CPU out there without affecting performance.
GPU side, the title scales to what settings you use. Which doesn't mean it's badly optimized, just that it uses a lot of features (Hairworks, advanced lighting/reflections, etc) that are VERY expensive for GPUs to performance. With Hairworks off, 1080p, my 2GB 770 GTX can handle High across the board, which is better then it can handle on "more optimized" titles I've brought recently (Evolve comes to mind). It's those super high end features that KILL performance, which is expected because they are very taxing to perform.

Tossing in my two cents to ALL;
As someone who has over 20 years supporting the 'End User' directly (yes the person asking for a replacement coffee cup holder that was built into their laptop!!) the problem most people are answering is from their technical understanding of the game rather than from the view of the 'End User'.
The End User 'sees' the Youtube video, the TV commercial, FLOODED at the store (pick one) with the 'in game video' constantly being replayed on screens in the store, and then looks at the glossy covered box and 'pictures' and that is all they know a 'computer should play'.
The main reason Consoles have succeeded is because when they do the same thing this it is ONLY way the game does play, because it is the same Console for all player, that is not even half close for the PC marketspace. Because JoeDumbUser who got that 'Walmart Black Friday Special 199 PC' thinks his computer should play the 'same as the commercials' because 'they can't advertise what it can't do! I can sue them for false adverts!" and that is where we have all the problems.
What is 'packaged', marketed, and sold "AS THE GAME" is the extreme systems we see W3 is 'best' on (OMG TitanX SLI!! THAT is just $2000 for the cards, not even cost to power the cards much less the rest of the computer system nor all that cooling!! OMFG!) and that is the problem. The problem is the 'lies' the companies are doing now for the games, case in point (for this discussion) is W3 (see previous link I provided above) totally changed from the 'promo game play' to actual end product. While somethings can be said about 'design changes while in development' honestly everyone can't argue they dropped down the graphics on PC SIDE to be on par with the PS4 so 'improve stability and performance' (aka the demands for a 'normal JoeDumbUser' as some are pointing too, it is well 'optimized for those 'generic' gaming systems "just like a PS4"). Honestly though this is false advertisement just as much as the total failure of the end product Aliens Colonial Marines as compared to the 'nearly done' E3 shown game footage that everyone was excited about. The same with Witcher, everyone seen (again back to my link) the 'footage' they expected and were wowed with, well to get that you need a rig like the Falcon Tiki (http://www.pcworld.com/article/2925172/review-falcon-northwests-console-sized-18-core-micro-pc-is-gloriously-overkill.html) to 'play' it like you 'seen it' and 'expect it' as shown by all these other links being tossed around using multiple Titan Xs.
In summary, the problem is marketing and packaging of expectations and overselling the product to the end users when it takes a impossible expensive systems for 'JoeDumbuser' to afford (I WANT a TIKI!!!) and should just 'settle' with their PS4 gaming experiences and shut up, is the real message here.
