rFDynHUD by CTDP

It is a new, feature rich, configurable and extendable dynamic HUD system for rFactor. It is configured through ini files, which are created and modified using the provided editor, which is kinda self-documentary.
rfDynHUD comes with its own intuitive editor which allows you to define when and which overlays are shown to you.

These overlays can be heavily customized to suit your needs. You can create different overlays for each session, car and mod.
