A videogame journalist flies over his hometown and nostalgically looks down, through rarified clouds, at a soccer field where he once played; a researcher navigates an eerie sky before realising that all clouds are inverted, as if inhabiting an alternative troposphere; a multitude of players gather in a sunlit, submerging Pacific archipelago, to which they have no more than a remote connection. Computer game images of weather and climate, as in these vignettes describing experiences with Microsoft Flight Simulator, may speak to memory culture, the aesthetic pursuit of photorealism, or the enjoyment of natural phenomena in safe, if not sanitised, environments. While attending to the atmospheric address of game images, this lecture deliberately recedes to the background, asking instead: what do these images, and how they are made, disclose about contemporary algorithmic image pipelines and the technical culture that produces them? Turning toward the archival present of networked game design and performance, the talk traces the macro-ecologies and micro-temporalities of media support systems through which weather is operationalised as a procedural gaming experience.
