I have two XFX R7700 video cards. I want to run OpenSCAD, but it requires OpenCSG support. I updated the XFX R7700 drivers, but OpenSCAD still isn't finding the OpenGL support it needs.
I'm running Windows 7 Pro. I really don't want to upgrade my OS... I'm concerned that if I buy a newer video card, I'll still have to upgrade my OS to get the OpenGL support I need.
So my questions are:
Is there OpenCSG support for the XFX R7700 card in Windows 7 64 bit Pro?
If I upgrade to Windows 10, are there newer drivers for the XFX R7700 that will give me the OpenCSG support I need?
If the above answers are both no, then is there another card that will work with Windows 7 that will give me the OpenCSG support I need?
If not, what card and OS do I need???
