I'm trying to port my application to use 64-bit architecture which I have done so it can compile and start properly. However if I'm launching my 64-bit build my viewport is black, while it still works fine on my 32-bit build.
Any ideas why this could be happening? I've tried building the Earth example shipping with GLScene as 64-bit and it works fine. As far as I can tell it does not do anything special?

Hm, please, describe in more details your environment and the version of GLScene that has been used.

I used the latest version from the SVN with RAD Studio 10.1 (Berlin). I'm testing on Windows 10 with Anniversary Update (14393). I'm using a GTX980 with the latest drivers from Nvidia (373.06).
I should probably mentioned that I've used an older version of GLScene up until now from 2007.

Hi ScarT,
More older versions of GLScene had mixed asm and delphi code in VectorGeometry and other units, now it's forbidden in RAD Studio. I've fixed it partially but in current version on Earth and other demos for win64 I have "floating point overflow" errors and can not find where to edit it yet.

Oh, that might explain it. Do you have any idea if previous versions failed as well? Or it is something that needs to be fixed?
