GVExamples in the distro (unzip and run). This is just v0.1.0, more examples and features coming in subsequent releases.
GV was folded into DGK when I switched to SDL2 and it optimized for more recent versions of Delphi.
GPT uses SDL3, it is designed to work on more compiler/windows versions and will have more/advanced features that will eventually be included. Will not be hampered by limitation of a compiler version not having feature X which prevents you from using it. As long as your compiler version can target win64 and have Unicode, then it should be able to work.
