# Hardware Optimization

The following are considerations for selecting GPU drivers mode on Windows:

Tesla Compute Cluster (TCC)

- Only for NVIDIA Quadro®, Tesla® and GeForce® GTX TITAN (though not officially communicated by NVIDIA).
- The GPU cannot be used for display.
- For Quadro, the default mode is WDDM.

Windows Display Driver Model (WDDM)

- For the NVIDIA GeForce® or Quadro.
- GPU shared for display and computation.

Memory allocation time

- WDDM >> TCC

Multi-GPU configuration improvement

- WDDM << TCC

Solutions:

1. Only use NVIDIA professional or GeForce® GTX TITAN cards with TCC.
2. Use the ViDi GPU Memory Optimization feature.
