Strange. With version 176, I doubled the frame rate at sea on mine. The only difference with 177, is that I compiled that same code with Visual Studio 2019 and I get slightly better FPS at sea than #176. I wonder if I should switch it back to VS 2017?

Good to hear. I already had the 2017 ready to upload at a moment's notice if it was still a problem, but it sounds like I can continue moving forward with 2019 for the x64 bit. The 32 bit still uses 2017 because Microsoft has deprecated XP support in the newer VS2019 toolkit (I think you can configure to continue using it, but it is more work than I deem worth the effort) and it is simply easier to keep using 2017 for those 32 bit versions because I want them to remain compatible for WinXP.
