Is there an external graphics card that supports directx 9?

Yes, there are external graphics card solutions that support DirectX 9, as most modern external GPUs (eGPUs) are backward compatible with older DirectX versions. However, the specific support for DirectX 9 will depend on the GPU model and the drivers provided by the manufacturer. Older eGPUs based on previous generation GPUs, such as NVIDIA GeForce GTX 600 series or AMD Radeon HD 7000 series, will typically support DirectX 9. Always check the specifications and compatibility of the particular model you are considering.
