"Rydermark developers" make bold claims which turn out to be nothing more than a Photoshop hoax
It would appear
was quick to jump the gun on a story
accusing NVIDIA of lying about full DirectX 9 support
. The story accused NVIDIA of not allowing developers to use 24-bit or 32-bit shader precision. Instead it claims NVIDIA forces developers into using 16-bit shader precision as the technique is faster. This is a problem as DirectX 9 compliancy requires 24-bit shader precision or better. "Rydermark" is not a commercially shipping application yet, and has had very little information published to confirm its authenticity.
The original story lacked any type of physical evidence and
claimed its sources were developers for the program.
Images allegedly proving that NVIDIA forces developers into using 16-bit shader precision were posted on
. The posted images compared a rendered scene in Rydermark 2006 between
It turns out the images "proving" NVIDIA’s wrongdoings were nothing more than poorly done Photoshopped images. The NVIDIA rendered image appeared to have blurrier water while the ATI rendered image had sharper water detail. However, the ATI rendered image just didn’t look right with poor cut offs and a creation date three minutes after the NVIDIA rendered image. A difference image of the two JPG files can be seen to the right, with the outline of the modified area clearly visible in the ATI image. This would suggest the NVIDIA image was the original source image, and that the ATI version was modified afterwards.
A difference of the metadata from both images reveals that the NativeDigest delimiter is identical for both images, but has two different InstanceIDs. This would be consistent with an image that was modified and saved twice. In the author's defense, images that are created and saved on his computer have distinct metadata tags that are very easily identifiable. These are not present in the two images supplied by
for "Rydermark" -- suggesting the images may not have been modified by the author.
There’s been an outcry of
images on various forums including
something resembling a rebuttal to this article
. Incredibly, a user from the
forums managed to track down some of the stock art used in the screen renders, and believes
the entire image is actually fraudulent
