Terminology

> External Sync
External Sync refers to a sync signal generated external to the system and used
as a reference to synchronize the frame update of displays attached to the
system.
> Framelock
Framelock occurs when multiple displays are synchronized so that the start and
end of the frame align for all displays.
> Mosaic
Mosaic creates one large desktop of monitors and appears as a single Desktop
to the operating system. Taskbars span across the monitors and applications
maximize across the Mosaic configuration.
> SLI
SLI is an acronym referring to an NVIDIA technology called Scalable Link
Interface that allows multiple GPUs to be linked together to improve rendering
performance. SLI implements multiple algorithms to improve performance, such
as Alternate Frame Rendering (AFR) or Split Frame Rendering (SFR).
Explicit SLI
•
Graphics APIs have evolved to give applications significantly more control
over GPU resources. Vulkan and DirectX 12 are often referred to as explicit
APIs, meaning that an application explicitly controls the GPU instead of the
driver. This explicit application control also applies to SLI where with Vulkan
and DirectX 12, applications can implement whatever scaling algorithm is
best for their needs. This is referred to as explicit SLI.
Implicit SLI
•
The SLI SFR and AFR algorithms were a GPU driver feature and transparent
to applications, meaning that applications would benefit from improved
rendering performance without modification. This is called implicit SLI.
> Swap Barrier
A swapbarrier refers to a mechanism where multiple displays or swapgroups on
multiple systems are synchronized so that all displays across all systems update
the displayed frame simultaneously. The term swapbarrier is also used to define
an API interface within a graphics API, such as OpenGL.
