OK, so after not being able to run FO4 because it crashes when I try to start a new game I realized a few things. It was the Intel driver crashing. I also remembered that a few weeks ago I suddenly couldn't see underwater in Skyrim. So after much installing and uninstalling of drivers to no avail I ran Skyrim from Steam rather than SKSE. It detected settings as low and shows only my Intel card.
The nVidia control panel shows that my nVidea card should be being used but it isn't. I've tried the newest and previous drivers for my card to no avail. Everthing in my system says my NV card is OK and set to work but niether Skyrim or FO4 seem to see it.
Help please!
