Does Fallout 4 Use Sli?

Fallout 4 is an action role-playing game that has been developed and published by Bethesda Game Studios. It was released in 2015 and quickly gained immense popularity. This post-apocalyptic game is set in the Commonwealth, a wasteland that was once known as Massachusetts. The game’s graphics and performance have been praised by many gamers. However, players with a multi-GPU setup may wonder whether Fallout 4 is compatible with Nvidia’s SLI technology that allows for better graphics rendering. In this post, we will explore whether Fallout 4 uses SLI and its impact on gameplay.

SLI or Scalable Link Interface is a technology developed by Nvidia that enables a multi-GPU setup. This technology allows games and applications to divide the workload between two or more graphics cards, thereby improving graphics rendering. SLI support is essential for gamers who aim for high-performance gaming. The question that arises is whether Fallout 4 supports SLI technology. Understanding the compatibility of the game with SLI technology would help players determine how much performance enhancement they can expect from a multi-GPU setup. In the following section, we will delve deeper into whether Fallout 4 can benefit from an SLI setup.
