This is for multicore processors, which pretty much every system is. Low is best if you have a low-end system with basic graphics. You can set it to low or medium based on your preference. This setting controls the amount of texture detail on the game characters. This option takes a lot of graphics resources so low is the way to go. It’s best to set it at low to get the max performance. Basically, special effects in the game will be at the lower end but this will save you a lot of FPS. Effect Detail: LowĮffect detail controls the amount of detail to be displayed during advanced physic effects such as explosions and blood spatter.

Set it at Bilinear for the best performance. Bilinear filters 2x whereas you can go up to 16x. This option forces texture render using specific methods for filtering. Experiment between on/off and determine what’s best for you according to your system. Note: On some Nvidia cards, you will actually get better FPS if you leave this option on at 2x. This will save you a lot of FPS in-game because this setting does not have a high impact on graphics Set anti-aliasing to None to get the best performance.

Resolution plays a very important role in optimizing performance and gameplay experience. Unless you have an ultrawide monitor you will have an aspect ratio of 16:9, set it to the default. The default is the best when it comes to performance and gameplay experience. Select Advanced Settings under your video options Advanced Settings in Video Options Aspect ratio: Default
