there a reason my game went from yeah, really good, no game hick ups, so texture issues, quests aren't bugged that you cant finish them to like... everything i just said?

i run around the game, I'm seeing parts through the world. I'm in a cave, and i can see a big fat triangle that when i look through it, i can see the outside world! i can see the sun and everything! and I'm well deep into this cave where there shouldn't be no giant ass triangles that deify reality... but i could possibly look past a few of these issues... but my main issues is that fact that!

i Cannot complete a lot of quests or world places i go to is because its bugged... okay... example... i got to a bandit camp, and there's a bandit leader who has a key to a cage to let someone out... fairly simple... i kill everyone, very simple enough... cant find the bandit leader... so i look around and i finally find him, hes stand still. not doing anything. i hit him, he doesn't move. i kill him. and hes still alive and doesn't drop any loot... wouldn't be a big issue... but the fact is i needed his loot to get the key to get the guy out of the cage... now that's just a side thing...

I'm at a quest where i need to go in the dungeon and kill some guy from the wild hunt, i get him down to low health because hes not moving, then he pops a shield and summons these little dog things... while the dog things are up he gets a shield that you cant attack him, so i killed the dogs, and once again, the bugs set in, he still has his shield up, and hes not moving. every time i got to attack the shield. it takes off like. 25% of my health or something... so i cant complete this MAIN story line quest to move on with the game... it does it for a hand full of side quests and other bandit locations around the game... ill see if i can attach some photo's or something soon. but its a big bloody stuff up if its to do with the new add-on there bringing out.

Sorry for the long post. trying to give you an idea on what I'm dealing with...

Well, he will put up his shield a certain amount of times only (if I remember this right, he does it three times).
And yes, while he is under his shield
- hounds will attack
- his shield will throw you back.

The only thing you will have to do is
- defeat the hounds
- hit him between shields
- eradicate him when he finally does not shield anymore.

All outside any bug issue, at the least for this perceived only "bug".

Right, there are some issues that will hit you under certain circumstances (outdated mods, NG+, wrong settings, etc.), but in general there are a lot less "bugs" (real ones) in W3 then the posts here on this forum might give the impression.

i think game with this bugs is unplayable - try reinstalling it.

Out of your three examples of how "bugged" W3 is, one has already be solved (see other answer).
For the rest:

- if you encounter graphical problems at a certain point in game (when it behaved quite well before), I would surely expect the video board misbehaving, maybe look for the most actual driver.
- you might have changed the version of your system (going from WinXX to WinYY), and there might be some problems there.
- you might run a mod/several mods that (after you might have patched W3) are not compatible with the patch.

There is more, but what I mean: you, like a lot of other folks here, are fast at hand in calling out "bug" when in fact you

- misunderstood one or more plot related things in game
- had not been aware that things you have done/installed/adjusted in fact were the culprit(s).
- did not download every part of a patch (no joke: there are people who did not).

I am not related in any way to CDPR/GoG, but W3 worked on my (at first slightly outdated) machine without a reason for me to nag.
And, because I can assure you that I am as average as average can get :) >>> I think that I did nothing special, meaning that W3 is in fact working quite well, right out of the box, for anyone.

Sorry for the long post, trying to give you an idea on what you are really dealing with :)...

I have the same problem with Mithral in the cave. He just stands there in the bubble. Can't continue the game.
