I only have a few gripes honestly. Apart from that the game looks absolutely fantastic!
-Some of the animations are a bit rough. Like the jogging one when Geralt's just getting out of the cave, (not to be mistaken with the running one, that one is fine imo), and also the jumping animation at that fence was a bit jarring.
-The hud has a bit too much clutter, experience gained on the side, damage numbers over enemies, and then a combat log showing both those again, it's a bit redundant, (not to mention it all taking up more space than needed, but I heard scaling is in so that's not an issue I suppose)
-The game choosing to show the name over the heads of every little animal like the geese and rabbits is also a bit much.
-Geralt literally whispering to Vesemir while they're on horseback talking about the Gryphon, I mean even if they were beside each other on horseback you'd still need to talk louder than just whispering.
-During that scene as well I noticed the lake water had some weird flickering, this was present in the 35 minute demo as well while Geralt was going through Novigrad, hopefully it's not some tech limitation and will be fixed by release.
-Vesemir's animation on the horse seemed to be running at a lower framerate than the horse he was on, hard to explain, but it's there, it seems to be a performance saving feature, but still, a bit of an issue nonetheless.
It was either that or his model was jittering on top of the horse giving the same effect as a lower framerate animation.
My biggest issue though is how the pop-in is handled. I know that pop-in can't be fixed, but it can definitely be mitigated. To not make it stand out so much.
Right now the various LOD levels just spontaneously switch, and it's because of that, why it's so noticeable.
What I find weird though is that CDPR had a pretty good solution in W2, instead of just making the LOD levels switch instantaneously, they had the vegetation and objects fade in, (using a dithering technique if I remember right), and it definitely helped make pop-in a lot less noticeable, and in Witcher 3 it's not present at all.
Here's an example of the pop-in in W2, (apologies for the low quality video and subpar scene to show it, I didn't have W2 installed at the moment so I couldn't video an example myself. But it shows it adequately I feel.)

I'm not extremely knowledgeable about the graphics effects used in games, so I'm just wondering if it's an issue of LOD fade-in taking too much render time away from the game, (because of the much higher amount of LOD's it has to switch out being an open world game) or just something else?
I felt it was a great method in W2 to reduce the visual effect of pop-in, and am wondering why they're not reusing the same method to reduce the jarring pop-in in W3.
