If there is a thread like this....oh well :(

The reason why I say the real one is that apparently there is a bug with the game that does not disable the extra DX10 features (water ripple, soft particles, enhanced shadows) even when set to of. I noticed that some sites were unaware of this and actually presented DX10 vs DX10 visual comparisons rather than DX9 vs DX10.

Thus if you want to see how bioshock looks (and runs) in DX9 mode and have got Vista you have two options. Either downgrade to Windows XP or add the line -dx9 to the bioshock shortcut essentially forceing DX9 and effectively disabling the DX10 head candy. Here are the results, stumbled upon accidentally when forcing DX9 mode in order to study visual quality with AA. IMHO big difference visually especially in motion. It was the first thing i noticed when I enabled dx9 mode.

Added a couple of movies. Movies are in 1280x800. Rightclick and save as.

Focus on the behaviour of the water in both the screenshots and videos

There's an obvious difference in the pictures, in the way the water reacts
to the characters moving through it.

I haven't watched the video's yet.

No way, there is an enormous difference in the way the water reacts. Check out my video:

Watched the videos and it's even more apparent in motion.

The DX10 effects in this case look great!

This makes me want to go play the game..lol..I'm off ! :captnkill:

I only looked at the pics. If you go just by that, then there isn't really any difference.

So its the water, then its not much im missing then, hardly worth it. Maybe in crysis the difference will be bigger.

Meh, not very impressed. Got a few more water ripples, big whoop.

The water actually reacts as opposed to it just making some white stuff.

You can do the same effect with DX9, I think Oblivion did it if I remember correctly.

Even Morrowind did it.

I know, I was just noting the difference in Bioshock.

The game does have the best water effects to date though.

I still think HL2 comes pretty close, slightly better reflections on Bioshock

I think EQ2 takes it for the best Water Effects...

Actually you might need your cataracts removed. :D The difference is plainly obvious and I have only seen the screenies.

I always thought the water effects were lame, as far as the way it responds to movement. I don't see any reason they couldn't have used the same effect in d9x.

I don't think any of us are qualified to make such a statement.

We do not know the exact way that 2K Games implemented these effects, maybe this makes use of the geometry shader?

The water effects as far as the dynamic rippling and distorting that you get when walking under pouring water are great. The splashes are the only thing that needs work.

Overall the game looks really good, but it's clear it's using low-res textures in some places. This isn't the first time I've seen a dynamic rippling effect, though. FEAR implemented this in DX9, and I also think it looked better.

So they created an effect with an exclusive api capability even though the affect can be created to give everyone the same experiance... ya wonderful.

We have seen better water in other games its not something special... the game makes it DX10 exclusive to please MS... not because it couldn't have been done.

Could it have been done in DX9?
Yes.

Could it have been done as efficiently?

I think that is the main question.

Yes it could have... I see NOTHING related to the water that hasn't been done already...

Other than the textures they use to simulate character interaction in DX9 I think the water is about the best I've seen.
