1. My graphics card is the AMD Radeon HD 7640G + 7670M Dual Graphics. It has a total of 5 GB of memory and 1.4 GB of dedicated video memory. (7640G is integrated, 7670M is dedicated)
2. I have all of the EP's installed.
3. I have High End loft stuff installed.
4. The only mod I have installed is overwatch.
5. I have 5-10 items of custom content. Sorry I couldn't do the size.
6. 30-40 fps
7. I cannot provide a screenshot but all of my settings are on high. I cannot download paint at the moment.
I have read that the AMD Radeon HD 7670M is better than the dual graphics due to micro stuttering. So perhaps you could add that graphics card as well?
