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.
