Yes. For full DirectX 11 hardware acceleration and performance, your graphics card driver must support DirectX 11. Ensure you have the latest official driver from NVIDIA, AMD, or Intel for Windows 7 64-bit.

Windows 7 natively supports DirectX 11. No separate, standalone “DirectX 11 installer” is required for the core runtime. However, many older games and applications may prompt you to install “DirectX” because they require legacy DirectX 9, 10, or 11 components not included by default in Windows 7.
