HD is the label on courses built for GSPro 4.0, released November 3, 2026. Version 4 moved GSPro to Unity 6 and supports all three of Unity's rendering pipelines (BIRP, HDRP and URP). GSPro has not published a detailed list of what changes inside an HD course.
GSPro 4.0 added an HD collection filter to its course list. The courses on this page are the HD courses listed on Simulator Golf Tour as of November 2026; the in-game filter may show more as designers release them.
GSPro said during the 4.0 beta that version 4 keeps full backward compatibility with existing courses.
