EnglishBin heute auf den folgenden Absatz eines a Artikels auf Gamasutra hingewiesen worden: Traditionally, IHVs have had to disable Z acceleration structures and algorithms when shaders write to the depth buffer via the oDepth register. The conservative oDepth feature in DirectX 11 enables shaders to write to the depth buffer within a specified region guarantee. [...]
The following part of a Gamasutra article was brought to my attention: Traditionally, IHVs have had to disable Z acceleration structures and algorithms when shaders write to the depth buffer via the oDepth register. The conservative oDepth feature in DirectX 11 enables shaders to write to the depth buffer within a specified region guarantee. This [...]
As we all know, none of the TV pictures of this U2/Green Day song really happened – it’s all CG / compositing of outstanding quality. A ‘making of’ was shown at the SIGGRAPH 2007 electronic theater. Download!
I’ve just taken a look at the FX Shader Compiler’s output for the broken shader, and what changes when I comment a few lines so that it doesn’t crash my machine any more… and figured out what the problem is. Here’s a fairly minimal shader that crashes my machine: PixelShader = asm { ps_3_0 defi [...]
Since the shader I crashed my system with does so extremely reliably, I decided to submit it as a bug report to NVIDIA. Which is a bit problematic, because this usually requires a ‘repro case’, ie. a piece of code which can reproduce the problem as repeatably as possible. Repeatability is easy – my shader [...]
