More on Video CardsMost modern cards made in the last 3-4 years should support DirectX 11. If your card does not support DirectX 11, you can use a compatibility mode but some features will not be available to you. It is strongly recommended to use a graphics card that supports DirectX 11.
If you use a 4K display (typically 3840x2160 or similar), 4 GB of Video RAM (VRAM) on your video card will likely be required, based on your designs. 6 GB of VRAM is recommended for 4K displays. If you do not have enough VRAM, you may experience sluggish visual performance during screen updates, for example during model rotation.
My system has the 16 gig of ram that I ordered but I know nothing about the V ram. The video card is an intel (R) 4600 which my It immersed buddy says is really basic low perfomance.. I am at a place where I need to be able to move sub assemblies and roll models which though rather simple it just freezes up on!!
Any comments would be appreciated. I cannot afford a 6-8hundred dollar video card. I Am running a decent Dell 20 inch monitor!!!! BUT NOTHING IS GETTING DONE OVER THE FREEZING UP ISSUE
