A graphics system may include a frame buffer and a hardware accelerator. The frame buffer may include a sample buffer and a double-buffered display area. The hardware accelerator may be coupled to the frame buffer, and configured (a) to receive primitives, (b) to generate samples for the primitives based on a dynamically adjustable sample density value, (c) to write the samples into the sample buffer, (d) to read the samples from the sample buffer, (e) to filter the samples to generate pixels, (f) to store the pixels in a back buffer of the double-buffered display area. A host computer may be configured (e.g., by means of stored program instructions) to dynamically update programmable registers of the graphics system to reallocate the sample buffer in the frame buffer in response to user input specifying a change in one or more window size parameters.
