Hence, we’ll take you through some methods of fixing FPS drops, lag & stuttering in Fallout New Vegas on your device.

Why do I suddenly have FPS drops?

Requirement issues with your computer: Users are liable to encounter many issues with their game if their computer meets the standard stipulated as the minimum required for the game. Hence, such may be the case, resulting in the Fallout: New Vegas 120 FPS issue.
Outdated graphics driver: The drivers on your computer are responsible for processing and organizing the programs on your computer. So, not keeping them up to date may affect how they interact with the component they are responsible for.
Outdated OS: When your operating system is outdated, your computer will not be able to access updates and patches for improving its performance and fixing bugs. So, it may cause FPS issues.

Is New Vegas locked to 60 FPS?

Your game can be capped at 60 because VSync is active by default in the game settings. Although the game may not have a lock system, the presence of VSync may lock it at a 60-frame rate.

An easy way of uncapping or unlocking New Vegas is by disabling VSync in the game settings.

When should I cap my FPS?

Capping your FPS should depend on your PC’s performance and capability to run the game smoothly. First-shooter games may experience stuttering and lag if the FPS fluctuates.
