Hello to everyone,
minor problems i noticed were:

1. Shadow quality was low even at highest setting (console like quality)

2. After every fight i noticed latency (5-6 sec) before you can loot or climb over obstacles

3.Door mechanic as mentioned before

Not so much concerned with shadows myself, though it could use improvements I do admit. They've got great lighting though, so I'm fine with the shadows being a bit dodgy.
That has nothing to do with the engine. It's deliberate in order to avoid exploitation and getting out of fights to easily. Granted, I was able to cheap out of combat many times, but they want combat to be strictly combat and not about looting and swinging.

Having just an option is pretty bad…
Having an informed option or an option used in context is good…
Having your own option and realising that so does everyone else and that they are all different takes some getting used to… :)

So, let me then say it that this thread is pretty good, but the quoted post of yours sounds like you expected everyone to share your opinions? :)

A valid observation…

I am simply conveying the feeling that threads like this are rare on major developers sites (or they get ignored and locked down pretty quickly)…
What I am asking for it for people to be honest with their comments and apply them to all products of interest…
I simply feel that very few people are seeing the bigger picture and actually comparing products and achievements on their demonstrated merits.

I was referring to the guy who said that having tessellation as an option for high end pcs would be bad.

My 2 cents:

The game runs decently in machines that can be call middle-end, at best.
It can be run in win xp 'cos doesn't requieres DX11, so you don't have to upgrade your OS to play game.

And if you run the game in high-end machine, is the best looking RPG ever.

The engine is not perfect, but it is great.

As MichiGen says...
"Witcher 2 is awesome (but my english is not,sorry)"

The comment can still apply to his reply then :)

"Ever" is a very long time :)

I can understand that. I just made the comment that I did because alot of times those kinds of comments come from fans who are so in love with the game they don't want to see anything bad being said about it. But I agree with you completely in this regard.

Not sure if "threads like this" would get "ignored and locked down pretty quickly", for what it's worth, it's mostly about what could be improved about the engine. It's not about bashing or baseless criticism.

There are haters and overzealous fans. So far I have seen none of those (yet) in this thread, and I hope it keeps this way.

p/s: If you consider "Bioware" and "Obsidian" to be "major developers", the "complain threads" or hate threads do exist. A lot.
Who is MichiGen? Just because a game "supports" DX11 doesn't mean that lower end computers won't be able to handle it. More than often, there are options to play in DX9, DX10 mode. So I don't see why game developers have to avoid from developing in DX11 (if they have the resources) because of the low-end computers.

I must have typed it long ago..

Did you OP mean

"Weakness of how graphics are present in Witcher 2"

or

"weaknesses_of_the_red_engine" (because I am quite confused, since no one has access fo RED engine either via SDK or tools except the developers/those involved in the development of Witcher 2)

Also there are certain features not mentioned to public in RED engine, without access to such info or tools, how can we discuss the weakness of RED engine in the first place.

About DX11 in the game.

Its not like copy paste DX11 command calls into a code and have a switch will magically appear to flip it on and off, its not like DX11 SDK will automatically split DX9 based API into multi threading rendering with a touch of a button.

There is no batch to automatically port existing Game's graphic engine which has a different base and had been developed with the base (DX9) code path from the initial stages..to be converted by a press of a button into DX11 code path.

For a game to be DX11, the game's graphical engine (ideally) has to be made with DX11 placeholders/implementation from the start....

I repeat again, non-existence of DX11 in Witcher 2 is not a weakness of the graphical engine in the first place. Its just the users(who are complaining) that its not there, zombies who are brain washed with AMD or Nvidia's marketing which forced them to by HIGH END GPU's and that tessellation is Mandatory without which the world will end. (cough cough) ..it is called Marketing and selling your product to customers by creating an environment of unnecessary need.

Best example, Witcher 2 with its Directx9 base graphics looks so GOOD....compared to other RPG games.

Pop-ins? Trying to sell Viagra again?
I am pretty sure Geralt has no need for it :)

Thanks for your insightful comment, once again.

Maybe to avoid the complications of having different rendering paths for different DX versions?

Also, maybe because they have nothing to say that requires DX11 to say it. Jumping on the latest technology just because it is there is a very good way to spend too much money. Using it because it allows you to make an artistic statement in a way you could not do otherwise is the proper justification. I cannot say that the art of TW2 was compromised by not having been rendered in DX11.

Yes, I agree with that. I'm just responding to the "fear" that if DX11 were to be implemented in TW2, the low end computers would have no chance to play the game at all.
