An open source re-implementation of the “NvDisplayConfigLDJ" tool with additional enhancements. This can be used to tweak your nvidia GPU driver settings to create custom display timings to address IIDX’s requirement if expecting proper display timings. This can also be used for any legacy IIDX versions that even expect very specific display timings, e.g. 59.95 or 60.05 hz. Furthermore, creating application profiles allows further tweaks to important GPU settings such as the current performance mode setting. This is crucial to ensure the GPU is not going into any kind of power saving states which results in non-smooth scrolling during gameplay and micro stuttering that cannot be measured on application level.

// FUNCTION NAME: NvAPI_D3D11_CreateDevice

//
|
|
//! DESCRIPTION: This function tries to create a DirectX 11 device. If the call fails (if we are running
|
|
//! on pre-DirectX 11 hardware), depending on the type of hardware it will try to create a DirectX 10.1 OR DirectX 10.0+
|
|
//! OR DirectX 10.0 device. The function call is the same as D3D11CreateDevice(), but with an extra
|
|
//! argument (D3D_FEATURE_LEVEL supported by the device) that the function fills in. This argument
|
|
//! can contain -1 (NVAPI_DEVICE_FEATURE_LEVEL_NULL), if the requested featureLevel is less than DirecX 10.0.
|
|
//!
|
|
//! NOTE: When NvAPI_D3D11_CreateDevice is called with 10+ feature level we have an issue on few set of
|
|
//! tesla hardware (G80/G84/G86/G92/G94/G96) which does not support all feature level 10+ functionality
|
|
//! e.g. calling driver with mismatch between RenderTarget and Depth Buffer. App developers should
|
|
//! take into consideration such limitation when using NVAPI on such tesla hardwares.
|
|
//! SUPPORTED OS: Windows 10 and higher
