Claypool, Mark L.
The goal of this study was to determine the effects of gamma and high dynamic range lighting on user performance and user perception of image quality in computer games. A user study was run in which participants played four different sessions of Counter-Strike: Source with varying gamma and high dynamic range values, while measuring user performance and gathering user opinions. Analysis of the results found that user performance was not affected by gamma or high dynamic range lighting. In addition, game playability and picture quality were similarly unaffected by these settings.
