Oh Fuck Yeah. lol...
Give me an example of a console game that has this shitty flickering, maybe I'm just used to it, because it's all I know and I'm used to it. Tell me what to look for?
Sounds Great, CDPR are really doing their best to gives us console players an even more awsome experience.

http://www.geforce.com/whats-new/guides/assassins-creed-unity-graphics-and-performance-guideI am quite a noob with all this AA, SSAO HBAO stuff so if someone can be kind enough to brief me via mp or else it would be very nice of him
This is quite a good "Simple English" explanation of the different AA techniques

That would be nice. I just watched one video that claimed to show the difference and it just hurt my eyes.
You do realise that if someone points out to you what to look for, you'll see it EVERYWHERE in your games from now on, and it'll start to really bug you?Oh Fuck Yeah. lol...

Anyway, that being said:
1. A sparkling effect on surfaces, often described as shimmer or twinkling, especially on surfaces that are highly-detailed with a lot of contrast at pixel level, like stonework, ground cover, concrete.
2. An effect like ants crawling up the side of hard-edged objects, especially if the object is diagonal.
In both cases, it's only there when there's movement in the scene. Personally, I find it more obvious when the movement is otherwise smooth - someone walking fast or running through an unobstructed area.

HaHa.. good call, 2 girls 1 cup! I'll take your advice and learn from your great wisdom.

I seem to get exactly this effect that I notice constantly on shadows, particularly during movement, in a very lot of games. I've never found a solution to fix the issue and it's jarring and nearly gamebreaking to me at times. Would TXAA or something similar actually solve that?
Alright here is my attempt at trying to capture Temporal Aliasing and Anti-Aliasing. I can see why there aren't any satisfactory videos... because it's very hard to capture it for some reason, compression etc makes it seem harder to notice. I've made it as 1:1 of a comparison as I can, and that's almost 99.5% same I must say.(Here's hoping this doesn't hurt your eyes, @Dragonbird)
First is SMAA which has no temporal properties by itself in this game and then it's TXAA, download and watch, short video, small filesize. Hosting on YT kills it with substandard compression:

Things to notice are everything except the protagonist, look AROUND him not at him. Shadow flickering is unaffected.
As soon as the video starts, look at the net on the barrel to your right, Then focus mostly towards the centre building - Rooftops, Windows, Barrels, Ropes, the stairs right in front of you. In the first section it will all flicker like mad as you move. There's also a lantern to your left that appears, notice how the entire structure on which its hanging flickers too. TXAA On eliminates most of the flickering or reduces it considerably.

Great example, and no, it didn't hurt my eyes. And yes, I suspect that the reason that we don't see good examples on Youtube is because compression destroys the evidence.
So what causes shadow flickering? Is it imperfect AO or something else?
Gather round, kids. There's plenty of articles you can read about Ambient Occlusion(AO) but why not a few pics from someone who's willing? I will again use AC4 in my example because it has everything I need.
Instead of putting two separate images and asking people to eyeball them between two tabs, I put some effort for something I've wanted to do... for two years and made a comparison slider for images(assuming it works).
So here you go, No Ambient Occlusion vs HBAO+

The difference is obviously visible so, what does AO actually do?
It adds shadows where two objects meet and calculates what kind of shadows to cast if something is blocking light from hitting another object.
As for SSAO and HBAO/HBAO+ the original method is SSAO, created by Crytek, that's been further modified over time into SSDO, HDAO, HBAO, SSBC and who knows what else, right now the highest quality solution we have so far is HBAO+.
They all have their 'issues' and limitations, SSAO for example adds haloing to objects at times or even overshadowing. HBAO+ solves some of these, hence why it's the preferred solution right now.
