quote: Without knowing what that image was supposed to be, you simply cannot conclude that the author's claims (which were related to the precision of some nVidia shaders) were true or false.
quote: SOME TWO weeks back we promised you screenshots to back up a story about a fudge on Nvidia benchmarks.
quote: But since the benchmark's author did not say what the image was supposed to be, for all you or I know, it could simply be the result of running a pre-rendered bitmap through some shader code, using a manually defined mask.
quote: Unfortunately it seems a lot of people like to comment on issues related to pixel shaders without even understanding what a pixel shader is. Pixel shaders operate in pixel space
quote: Saying that "it looks just like a filter was applied in Photoshop, which proves it wasn't a pixel shader" is a demonstration of ignorance
quote: Of course, it's easier to make a lot of noise and vote down posts that point out your ignorance than it is to actually go learn something about it. But the problem with that approach is that you continue to be ignorant.
quote: First, Fudo (who will believe just about anything, and misunderstands half of what he's told) is not the author of the benchmark ..(blah blah blah).. as a way to dismiss (or avoid addressing) that claim.
quote: Second, tons of benchmarks use stock / public domain images that can be found on the web (does the name "Lenna" ring any bells?). Your point was...?
quote: Third, "screenshot" is not the same as saying "a 3D render". Lots of benchmarks include 2D tests, and there is no fundamental difference between running a pixel shader on a 2D bitmap or on a 3D scene.
quote: If, as you claim, you've "had your hands on tons of game code" (more than I can possibly image - whoah! you must be John Carmack's smarter brother), you must know that.
