When I play Deus Ex GOTY, I have problem with 32-bit color depth. Some areas do not look right. You can look at screenshots below.

I have latest display drivers installed (Radeon X1950GT). System is Win XP SP3.

Does anyone know what is the problem?

Thanks for reply. Yes Im talking about shadows and light and different levels of it. Funny thing is that 16-bit looks better, but in 16-bit there is some kind of small pixel grid over the screen.

For example shadow between boxes. Thats what Im talking about.

I tried different renderers D3D9 and Open GL. Didnt help. How can I change renderer settings? Do you mean display settings in the game?

It should not look like this in 32-bit.

If you don't have DX10 the renderer will be useless to you.

No DX10 card no DX10, how hard can this be?

So it's "hypothetically, if I had a DX10 card, would DX10 fix this?"

I don't think so, no. I've just tried my own install with basically every renderer going (that is sub-DX10, admittedly) and the ultimate conclusion I come to is that DX simply can't handle very, very small differences in darkness.

If you imagine a light source, immediately around it you've got "max light" falling off at the inverse square, so the gradient in illumination is wide, over a short distance: Well-lit areas look pretty.

Further from the light, it drops off much slower, over larger distances. And DX has to map this to a linear gradient of lighting, which means you have a huge swathe of texture at "0", a huge swathe at "1", a slightly less huge swathe at "2", and so on, and it just doesn't do it very well: Dark areas look less good.

More modern games probably fake it with dynamic range and so on, and/or simply have a better range in the first place, but yeah: conclusion is (if it's the muddy shadows you're taking issues with) that it's fundamentally a game thing, not a renderer issue.

However, it does look BETTER under some renderers than it does under others (on mine the latest openGL looks nicest), and of course, because DX texture lighting is based somewhat on the texture size to be lit, bigger textures render better than smaller ones, so install (http://www.moddb.com/mods/new-vision) new vision.

Oh, and install HDTP too (personal plug etc). :)
