that despite the numerous steps taking to force the program to use my dedicated GPU it's still using the integrated graphics. Might this have something to do with it?
1. Make sure your power options are set to High Performance
2. Make sure your video card control panel is forcing the 3D card for this game
3. If you have Geforce Experience, disable that (it is a know problem for games, ironically)
This whole 2D/3D switch is why I bought a motherboard that has no video capabilities. Although my laptop seems to sort this just fine with the Power Options.
If the above is not working to fix this, and your game was working last week, then use the Launcher to do a Repair.
