I would like to upgrade from X-Plane 10.5 to X-Plane 11; I tested my current computer, it was found to be lacking & in-order to purchase X-Plane 11, an upgraded computer is needed. May I ask, if X-Plane 11 is used primarily as a hard IFR (low ceiling, low visibility) trainer with minimal need for outside scenery, is a separate video card needed? This is the hardware that's being considered: HP Pavilion Desktop, Windows 10, Intel Core i7-7700 Processor, Quad-Core, 3.60GHz 8032; 12GB RAM; Integrated Graphics Coprocessor. Will this hardware be sufficient? Thank you.
