A few hints for dedicated AMD GPUs on Windows and good settings i found working well.
Use a recent driver version, at least "AMD Software: Adrenalin Edition 22.7.1." which added massive improvements to OpenGL performance. Newer tends to be better.
Enable "OpenGL Triple Buffering" and disable VSync (called "Wait for vertical refresh"):
Don't bother with HBCC Memory Segment, its just slower, keep it disabled.
If your GPU is new enough (RX 6xxx) and your motherboard supports it, you should enable the "PCIe Resizeable BAR" support. This usually takes some form of BIOS Setting that must be enabled, and a setting in the AMD driver, where it is called "Smart Access Memory".
If you have a GPU that is too old (e.g. RX Vega), you may tweak some registry setting to still allow it to be activated. This thread has some hints how to do it:
