- Adjust FOV (Field of View): Reducing the FOV can improve performance by decreasing the number of objects rendered on-screen, leading to higher FPS, especially in crowded areas.
- Disable Unnecessary Effects: Turn off effects like motion blur, depth of field, and ambient occlusion. These can heavily tax the GPU without providing significant visual benefits.
- Use Mods for Optimization: Consider using performance-enhancing mods that help streamline the game, such as optimizing textures or reducing the number of NPCs in certain areas.
Can Mods Impact CPU and GPU Usage?
Yes, mods can increase CPU and GPU usage. Graphical mods with 4K textures demand more from the GPU, while mods that add NPCs or gameplay changes put extra strain on the CPU.
Too many mods or poorly optimized ones may cause frame drops or crashes. Balancing mods with your hardware’s capability ensures smoother gameplay.
Does Resolution Influence CPU or GPU Usage?
Resolution affects the GPU more than the CPU. Higher resolutions like 1440p or 4K require more GPU power for rendering, while 1080p puts less strain on the graphics card.
However, CPU-heavy areas—like battles or large towns—still need a strong processor. Raising resolution shifts more workload to the GPU, reducing CPU bottlenecks.
Which GPU Works Best for Fallout 4?
The Nvidia GTX 1060 or AMD RX 580 work well for smooth 1080p Ultra settings. Better cards like the RTX 2060 or RX 6700 XT are recommended for playing at 1440p or 4 K. A strong GPU ensures smoother performance, especially with features like shadows and anti-aliasing turned on.
