Only limited research in the literature focused on assessment of different spatial and temporal resolutions. In addition, the field of synthetic video compression, such as video compression in game streaming, was the focus of only a few research papers. This paper will consider a wide range of synthetic video textures and motion speeds. The visual quality of the compressed video sequences is perceptually evaluated using the Double Stimulus Impairment Scale (DSIS) assessment metric. Extensive subjective viewing tests to evaluate user satisfaction are performed. A methodical analysis to study the influence of different dimensions on Mean Opinion Score (MOS) is presented. The study considers a wider scope of dimensions that affect the perceptual visual quality. MOS results are shown in details for different bit rates, frame rates and frame resolutions. This study contributes novel ideas that should provide common rules for online game streaming over transmissions with relatively low bit rates.
