I have a c++ program I’m developing that uses OpenGL. When I compile it as 32-bit it works fine, when I compile it as 64-bit the OpenGL is very, very slow. I’m using Windows SDK version 10.0.17763.0. I’ve tried a few others and see the same thing.
Make sure that you have the latest graphics drivers for your GPU installed. See this page for details:

that fixed it, runs fine on 32 and 64 bit, thanks!
