You should have patience during the installation in general. The process, which can take up to a couple of minutes in extreme cases, can be stopped, but the game will give you a warning that the performance might be affected. In return, the shaders have to be preloaded when you launch the game for the first time or change the hardware or the system, respectively.
While you still had to wait for multiple minutes before a mission started in the predecessor, even with a Solid State Drive, the missions now start surprisingly quick even on HDDs. We especially like that the developers worked on the loading times. Compared to a typical first-person shooter, Infinite Warfare does have its graphical highlights and looks decent up to good. Not even graphics blockbusters like Doom or Rise of the Tomb Raider, which raised the bar quite a bit, can beat Battlefield 1. This includes Titanfall 2, Mafia 3, Deus Ex Mankind Divided or Far Cry Primal, all of which were launched in 2016. However, we have to say that there is currently no action title that could challenge Battlefield 1 in the graphics department.
