## Supported GPUs
As this uses a proprietary NVIDIA API, the supported devices are limited to NVIDIA GPUs.
Additionally, the NVFBC API is only officially supported on GRID, Tesla, or Quadro X2000+ GPUs.
Unofficial support is possible by applying a [patch](https://github.com/illnyang/nvlax/) to the NVFBC library.
Unofficial support is provided for other GPUs.

## Supported capture types
Currently only CUDA and system (RAM) capture types are supported.
