David is getting an incompatibility error when updating to Windows 10. Does he need a new video card? Leo says no, that isn't necessary. The updated drivers should be out in a relatively short period of time. So David should just wait for a new video driver to become available before he updates. He has up to a year to upgrade for free.
From the chatroom, there are some older video cards from NVidia that Microsoft said will not support DirectX 12 for Windows 10. If that's the case, then he will have to get a new video card. But they're pretty cheap these days.
