# GPU Driver Mode Selection

Consumer-grade gaming-oriented NVIDIA devices only support the WDDM device driver model. 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.
Note: If using a GeForce-branded card, be aware that NVIDIA drivers are updated frequently and may not be compatible with VisionPro Deep Learning.
