# GPU Driver Mode Selection

Consumer-grade gaming-oriented NVIDIA devices only support the WDDM device driver model A specific spatial arrangement of a set of features (Blue Locate and Blue Read tools only.) During a post-processing step, the Blue Locate and Blue Read tools can fit all of the features detected in an image to the models defined for the tool. The overall pose and identity of the model is then returned.. This driver is intended to support graphics display, not computation. Professional-grade NVIDIA cards support the TCC driver mode, which provides better performance and stability.

The following table describes some considerations for selecting the GPU drivers mode:

Tesla Compute Cluster (TCC) | Windows Display Driver Model (WDDM)
Memory allocation time is faster with TCC. Only for NVIDIA RTX / Quadro®, Tesla® and GeForce® GTX TITAN (though not officially communicated by NVIDIA). Only use NVIDIA professional or GeForce® GTX TITAN cards with TCC. The GPU cannot be used for display. Using TCC mode driver prevents the use of Video output on the GPU card; use onboard video instead. For NVIDIA RTX / Quadro®, the default mode is WDDM. Diminishes or eliminates the advantages of using Deep Learning optimized memory. Configured using the NVIDIA-SMI utility. | WDDM allows for better multi-GPU configuration. For the NVIDIA GeForce® or NVIDIA RTX / Quadro®. GPU shared for display and computation.

Note: It is recommended to use the GPU Memory Optimization feature A feature is a visually distinguishable area in an image. Features typically represent something of interest for the application (a defect, an object, a particular component of an object)..
Note: If using a GeForce-branded card, be aware that NVIDIA drivers are updated frequently and may not be compatible with VisionPro Deep Learning.
