Abstract: One embodiment sets forth a method for associating each stencil value included in a stencil buffer with multiple fragments. Components within a graphics processing pipeline use a set of stencil masks to partition the bits of each stencil value. Each stencil mask selects a different subset of bits, and each fragment is strategically associated with both a stencil value and a stencil mask. Before performing stencil actions associated with a fragment, the raster operations unit performs stencil mask operations on the operands. No fragments are associated with both the same stencil mask and the same stencil value. Consequently, no fragments are associated with the same stencil bits included in the stencil buffer. Advantageously, by reducing the number of stencil bits associated with each fragment, certain classes of software applications may reduce the wasted memory associated with stencil buffers in which each stencil value is associated with a single fragment.

Abstract: In typical embodiments a three GPU configuration is provided comprising three discrete video cards, each connected to a standard monitor placed horizontally for a 3× horizontal resolution. In this configuration, depending on the load on each GPU, the vertical split lines are dynamically adjusted. To adjust the load balancing according to these virtual split lines, the rendering clip rectangle of each GPU is adjusted, in order to reduce the number of pixels rendered by the heavily loaded GPU. These split lines define the boundary of the scene to be rendered by each GPU, and, according to some embodiments, may be moved horizontally. Thus for example if a GPU has a more complex rendering clip polygon to render than the other GPUs, the neighboring GPUs may render the rendering clip polygon it displays plus a portion of the rendering clip polygon to be displayed by heavily loaded GPU.
