This is almost not worth responding to, but I'll give you the benefit of my doubt.

My crate images clearly show SSAO is off. My instructions said:

Yours is on. That is the only shading you see. It is not responsible for entire walls of darkness, and it is cannot be not responsible for the blackened crate plank if the setting was off.
This is getting silly ..

I did not post a single pic with a crate because there is no point to do so. The darker panel on the lower side of the crates which you are prolly refer to is added alone by switching Rendering Quality from "Low" to "High", with all other settings staying the same ("Low"/"Off"). Any shade/shadow added further is drawn by enabling SSAO in "High" quality mode but changing the Shadow setting adds absolutly nothing to a crate.

If you insist i will upload a series of pictures showing both crate and my setting in effect on the same screen but since anyone out there can do this by themself it's totally pointless.

Here's what the game looks like for me with those settings. Look at the difference between these two screenshots. Yours has horrible color banding on the entire screen.

What's your [video] hardware?

This is what I 'm seeing, but I've got an old Nvidia Card; and that's on the highest settings.

GT 610, Linux x86_64 drivers 331.38.
I doubt I can usefully reproduce the problem in the OpenGL version of the game. I just thought it would be useful to show a screenshot of how it should (roughly) look, since at least one person appears to be convinced that the wrong behaviour is the right behaviour.

I can't be certain with only JPEG screenshots to go off of, since that format does not have any useful pixel information, but it looks like the shadow and SSAO interpolation in those screenshots is only using 12 or 16 color bits instead of 24. Looks pretty jarring when the other areas are 24-bit.

Looking at the upper part of the pillars in your pic this does not look like "High" render to me.
Compare it with my "Low" render pic, they are almost identical.

You can clearly see SSAO in my screenshot. Look at the back wall. If you look carefully you'll see the pillars' shadows too.

Of course it doesn't look like your screenshot. That's the point. Your screenshot shows messed up rendering.

Sorry, but this looks pretty much like this to me (beside different dimensions):
If that's SSAO in your pic it's very very slight.

Then again we compare pix taken from Linux with pix from Win and AFAIR they use different render algorithms.

Here is a side-by-side comparison with the difference highlighted.

Well what can i say? My regular settings are like Issac's all on "High", the color depth of the resolution is 32 bit and BMP's taken with Fraps alike with JPG's taken with Steam Overlay both state they use 16M colors.

For those that can't discern any difference...

I have Fraps, but I actually used Grimrock's built in support for the 'print screen' key, and saved as Jpegs of 96% quality.

I think it must be OpenGL... I wish the Windows version optionally supported OpenGL. :?

Most of my favorite games supported both.
