Yes you can remove shadows by changing the main shadow map resolution to 0, but for interiors this will gives me a 2 fps performance hit and a 30 fps performance hit outdoors. You can also change the shadow LOD settings to 0 but that removes the lighting effects on objects which have been present since Oblivion. Any other way to turn off shadows? In my rig, shadows impact performance the most. If I make all settings the lowest they can go in the launcher, I still get the same <20fps with ultra shadows. At both 1080p and 720p. Even at 720p, medium shadows have 10fps less than low. IMO, low-high shadows look terrible. Ultra aren't perfect but they look better. I'd like to turn them off altogether but don't think it is possible. Ideally, playing like Oblivion/FO3&NV would be nice.
