Micro stuttering is a term used in computing to describe a quality defect (https://en.wikipedia.org/wiki/Software_bug) that manifests as irregular delays between frames (https://en.wikipedia.org/wiki/Film_frame) rendered by the GPU(s), causing the instantaneous frame rate (https://en.wikipedia.org/wiki/Frame_rate) of the longest delay to be significantly lower than the frame rate reported by benchmarking applications, such as 3DMark (https://en.wikipedia.org/wiki/3DMark), as they usually calculate the average frame rate over a longer time interval. In lower frame rates[note 1] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-1) when this effect may be apparent the moving video appears to stutter, resulting in a degraded gameplay (https://en.wikipedia.org/wiki/Gameplay) experience in the case of a video game (https://en.wikipedia.org/wiki/Video_game), even though the frame rate seems high enough[note 2] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-2) to provide a smooth experience. Single-GPU configurations do not suffer from this defect in most cases and can in some cases output a subjectively smoother video compared to a multi-GPU setup using the same video card (https://en.wikipedia.org/wiki/Video_card) model. Micro stuttering is inherent to multi-GPU (https://en.wikipedia.org/wiki/Graphics_processing_unit)configurations using alternate frame rendering (https://en.wikipedia.org/wiki/Alternate_Frame_Rendering) (AFR), such as nVidia SLi (https://en.wikipedia.org/wiki/Scalable_Link_Interface) and AMD CrossFireX (https://en.wikipedia.org/wiki/AMD_CrossFireX) but can also exist in certain cases in single-gpu systems.[1] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-3)[2] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-4)[3] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-5)[4] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-6)The effects of micro stuttering varies depending on the application and driver (https://en.wikipedia.org/wiki/Device_driver) optimizations (https://en.wikipedia.org/wiki/Program_optimization). Beyond dual-GPU setups, CrossFireX/SLI setups do not seem to be as affected by micro-stuttering; the frame rate variability in a three-way CrossFireX/SLI setup approaches the smoothness achieved by a single GPU.[5] (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-toms_hardware-7)As of May 2012, with the latest release of hardware and drivers from nVidia and AMD, AMD's Radeon HD 7000 series (https://en.wikipedia.org/wiki/Radeon_HD_7000_series) is severely more affected by micro stuttering than nVidia's GeForce 600 Series (https://en.wikipedia.org/wiki/GeForce_600_Series). In tests performed inBattlefield 3 (https://en.wikipedia.org/wiki/Battlefield_3), a configuration with two GeForce GTX 680 in SLi-mode showed a 7% variation in frame delays, compared to 5% for a single GTX 680, indicating virtually no micro stuttering at all. A configuration with two Radeon HD 7970 in CrossFireX-mode, on the other hand, showed an 85% variation in frame delays, compared to 7% for a single card, indicating large amounts of micro stuttering. These results are reflected in the perceptual experience when looking at the outputted video.[6 (https://en.wikipedia.org/wiki/Micro_stuttering#cite_note-swec-8)
