Ran perfectly. AC3 has suddenly started using integrated graphics. Other, more intensive games (Hitman 2), run very well so its a program unique issue. Even my work laptop runs it better now. Checked and there is 0% GPU usage when I'm playing. I have a 1060 3GB. Also used NVidia control panel, 3D settings, changed openGL settings on the program to use the graphics card but no difference. Any guidance on how to make it use the GPU?
