Blotchy Graphics

[spruten 10]

In OA, at night especially, everything looks "blotchy," and as if colors on the screen don't transition smoothly and gradually into different shades, but have sharp gradations. This is most noticeable with clouds, smoke, dust, etc.

I think that this may be a problem with the drivers, because I get the same blotchiness on Grand Theft Auto III. There it is also most noticeable in dark areas. I have tried the 11.10 Preview 1 and 3, and the 11.9 drivers. I even installed them "properly" (safe mode, registry clean, etc.).

Also, my grass is white when I stand still. It gets its color back when I move straight, but when I turn and move it loses its color again.

I am using the default graphics settings (All Normal, 1600 view distance), except I've change the 3d resolution to equal the screen resolution. I am running OA on Win7x64, Phenom II x4 955, XFX 5850, and 4GB RAM. I have not overclocked anything.

How can I fix this?

Thank you.

does the video memory setting do anything? Maybe lower textures. That might get rid of the white grass.

About white grass, look here for example.

Have a play with the Gamma level for the blotchiness

That "blotchy" thing is actually color gradings. It will happens when the HDR color is lower than 16 bits. You can try to fix that by setting the HDR quality to "High" or "Very High".

The AToC setting and the HDR quality setting fixed everything. Thanks.

If you set HDR above it's default then there are a few quirks with it, like the lasers from the rifles looking all funky and massive performance drops. But other than that it does make it look much much better, especially at night.
