I've been playing the game Halo 2 Vista recently on two different computers, a tablet and Intel NUC. Both are running on Intel HD Graphics 4200 and 5000 respectively. However, while playing Halo 2, I see lines, outlining the polygons on textures, usually shiny or glowing textures, constantly flash. It looks almost like the game is running in a hybrid of wireframe and regular graphics mode. Why is this happening?
