How to Increase FPS: Comprehensive Guide

How to increase fps? Game developers and testers must implement strategies to increase games' FPS speed by optimization of CPU, GPU, memory and assets.

In the gaming universe, FPS (frames per second) is a significant index that helps to define the quality and accuracy of the gaming experience and there is a continuous urge about how to increase fps among the game testers and developers. A higher FPS refers to the lack of stuttering and smoother movement of the animations, reduction of lag, and the creation of a more immersive environment. 
In addition, achieving a smoother and higher FPS over the long term is often a tricky undertaking, primarily for intense games which require high hardware specifications. In this article, we will review the methods and approaches which can be applied by game developers and testers to achieve better game performance with high FPS. 

Understanding the Bottlenecks

Before increasing FPS in games, it is essential to identify performance-limiting factors. These bottlenecks may occur in hardware components such as the CPU, GPU, RAM, storage, or even the game engine itself. Identifying the root cause of performance issues is the first step toward developing efficient solutions to achieve higher FPS in games.

CPU Optimization

Optimizing CPU performance is crucial for high-end gameplay, as it handles the game's logic, AI, and physics simulations. Developers can follow these steps to create CPU-optimized games:

  1. Multithreading: Distribute the workload across multiple CPU cores for higher efficiency.
  2. Code Profiling: Analyze runtime code to identify and optimize bottlenecks during gameplay.
  3. Data Structures: Choose efficient data structures and algorithms to save time and memory, avoiding processing overhead.

GPU Optimization

GPU optimization is another critical aspect of increasing FPS, as the GPU handles graphics bitmap rendering. Its performance directly affects FPS. Developers and testers can adopt the following techniques:

  1. Level of Detail (LOD): Create a hierarchy of meshes, textures, and effects based on the camera's direction.
  2. Occlusion Culling: Identify and remove renderable objects that are not visible to the player.
  3. Deferred Rendering: Modernize the rendering pipeline by implementing geometry and lighting rendering stages.

Memory Management

Efficient memory management is essential for smooth gameplay, especially in complex gaming environments. Streaming techniques such as object pooling, resource caching, and texture compression reduce the memory footprint and improve game performance.

Asset Optimization

Game objects, like models, textures, and audio files, are significant sources of FPS loss. Optimizing these assets using techniques such as polygon decimation, texture compression, and audio compression can help developers reduce loading times and memory usage, contributing to higher FPS.

Engine-Specific Optimizations

Different game engines provide a wide range of optimization tricks and strategies. Developers should familiarize themselves with the engine's guidelines and best practices to fully utilize engine-specific optimizations and develop games with higher FPS.

Testing and Profiling

Regular testing and profiling are crucial for detecting and addressing performance issues in the game development lifecycle. Tools such as performance profilers, frame debuggers, and automated testing frameworks help developers and testers identify performance bottlenecks and verify the effectiveness of optimization efforts. WeTest offers a comprehensive PerfDog solution to help game testers and developers conduct thorough testing and implement strategies to increase game performance by optimizing FPS.

Progressive Enhancement

Instead of targeting a single performance level, developers should consider different levels of performance and use engine scaling technology to adapt the game's visual fidelity and complexity to available hardware resources. This ensures smooth gameplay with high FPS across various devices and configurations.


Optimizing performance and increasing FPS require expertise in hardware, software, and engine-specific details. By following the methods described in this article, game developers and testers can create high-quality, flawless, and thrilling game experiences for gamers across a wide range of hardware configurations.
