The question of whether you lose frames per second (FPS) in borderless windowed mode compared to fullscreen exclusive mode has plagued PC gamers for years. The short answer is: it depends. Generally, yes, you can lose some FPS in borderless windowed mode compared to a true fullscreen exclusive mode. However, the magnitude of the loss varies greatly depending on your system, the game, and your settings. Modern operating systems and “fullscreen optimizations” have blurred the lines, making the difference less pronounced than in the past. Let’s dive deeper into why this is and explore the factors that influence your performance.
The Core Differences: Fullscreen vs. Borderless
Understanding the underlying differences between these display modes is crucial to understanding the performance implications.
- Fullscreen Exclusive (True Fullscreen): In this mode, the game has exclusive control of your display. It directly communicates with your graphics card, bypassing the Desktop Window Manager (DWM). This means that the game can optimize resource allocation for maximum performance. Older games typically used this.
- Borderless Windowed (Fullscreen Borderless): In this mode, the game runs in a window that is the same size as your screen, without the visible window border. It’s essentially a maximized window. The DWM is still active, compositing the game along with other desktop elements.
- Windowed Mode: The game runs in a regular, resizable window, allowing you to see other applications simultaneously.
Why Borderless Can Impact Performance
The potential performance hit in borderless windowed mode stems from the fact that the DWM remains active. The DWM is responsible for managing all the windows and graphical elements on your desktop. While it is designed to be efficient, it still consumes resources.
- Double Buffering and VSync: Borderless windowed mode typically forces double buffering with VSync. This can introduce input lag and limit your FPS to your monitor’s refresh rate.
- Resource Contention: The DWM needs to share system resources (CPU, GPU, and memory) with the game and other running applications. This competition for resources can lead to performance degradation.
- Compatibility Issues: Some older games may not be fully optimized for borderless windowed mode, leading to unexpected performance issues.
Fullscreen Optimizations: A Modern Twist
Windows 10 and 11 introduced “fullscreen optimizations” designed to improve the performance of games running in borderless windowed mode. These optimizations aim to provide a near-fullscreen experience, often leading to minimal performance differences between the two modes. However, these optimizations are not perfect and can sometimes introduce their own set of problems, such as stuttering or input lag.
Factors Influencing Performance
The actual difference in FPS between fullscreen and borderless windowed modes depends on several factors:
- Hardware Configuration: High-end systems with powerful CPUs and GPUs are less likely to be bottlenecked by the DWM, resulting in smaller performance differences.
- Game Optimization: Well-optimized games are more likely to perform similarly in both modes.
- Resolution and Graphics Settings: Higher resolutions and demanding graphics settings will exacerbate any performance differences between the two modes.
- Background Processes: Running resource-intensive applications in the background can further impact performance in borderless windowed mode.
- Operating System and Drivers: Newer operating systems and up-to-date graphics drivers often include optimizations that improve performance in borderless windowed mode.
The Upsides of Borderless Windowed Mode
Despite the potential performance hit, borderless windowed mode offers significant advantages in terms of convenience and multitasking:
- Seamless Alt-Tabbing: Switching between the game and other applications is much faster and smoother in borderless windowed mode.
- Multi-Monitor Support: Borderless windowed mode makes it easier to use multiple monitors, allowing you to quickly glance at other applications or information without minimizing the game.
- Streamlined Workflow: It integrates more seamlessly with your desktop environment, allowing you to easily access chat programs, web browsers, or other tools while gaming.
Making the Choice: Fullscreen or Borderless?
Ultimately, the best display mode for you depends on your priorities. If you prioritize maximum performance and are willing to sacrifice convenience, fullscreen exclusive mode is generally the better choice. If you value convenience, multitasking, and seamless alt-tabbing, borderless windowed mode is a viable option, especially if your system is powerful enough to mitigate any potential performance loss.
Frequently Asked Questions (FAQs)
1. Does Fullscreen Borderless Give More FPS?
Generally, no. Fullscreen exclusive (true fullscreen) can potentially provide higher FPS compared to borderless windowed mode, especially on older systems or with poorly optimized games. However, modern “fullscreen optimizations” have narrowed the gap, and in some cases, the difference is negligible.
2. Does VSync Reduce FPS?
Yes, VSync can reduce FPS. It synchronizes the game’s frame rate with your monitor’s refresh rate to prevent screen tearing. If your game’s FPS is higher than your monitor’s refresh rate, VSync will cap the FPS, potentially limiting your maximum performance.
3. Is Fullscreen Better Than Windowed Borderless for Gaming?
It depends on your priorities. Fullscreen exclusive can offer better performance but restricts multitasking. Borderless windowed offers convenience and easy alt-tabbing but might come with a slight performance penalty.
4. What are the Pros and Cons of Borderless Window?
Pros: Easy alt-tabbing, seamless multi-monitor support.
Cons: Potential for slightly lower FPS, potential for input lag.
5. Do You Lose Performance By Playing In BORDERLESS WINDOWED?
You can lose performance, but the impact varies depending on your hardware, the game, and your settings. Modern “fullscreen optimizations” often minimize the difference.
6. What is the Difference Between Fullscreen and Exclusive Fullscreen?
Fullscreen often refers to borderless windowed mode in modern games. Exclusive fullscreen gives the game exclusive control of the display, bypassing the DWM.
7. Does Fullscreen Increase FPS?
Exclusive fullscreen can potentially increase FPS by giving the game exclusive access to system resources.
8. Does Full Screen Optimization Increase FPS?
Fullscreen optimizations in Windows aim to improve the gaming experience in borderless windowed mode, but they can sometimes introduce slight performance drops or stability issues.
9. Does Fullscreen Improve Framerate?
Potentially. Exclusive fullscreen can improve framerate by allowing the game to fully utilize the graphics card and CPU.
10. What is Better for FPS Windowed Fullscreen or Fullscreen?
Fullscreen (exclusive fullscreen) is generally better for FPS, while windowed fullscreen (borderless) is better for convenience.
11. Is Fullscreen Borderless Better Than Fullscreen Exclusive?
Fullscreen exclusive is usually better for performance, but borderless windowed offers convenience. There is no benefit from using fullscreen if there is borderless windowed, unless the game is broken in borderless.
12. What Does Exclusive Fullscreen Do?
Exclusive fullscreen gives the game exclusive control of the display, allowing it to bypass the DWM and potentially optimize resource allocation for maximum performance.
13. Why do I Get More FPS in Windowed Mode?
This is less common but can occur on some systems where the discrete GPU sends frames to the integrated GPU for output in fullscreen, causing a bottleneck.
14. Does FXAA Increase FPS?
FXAA (Fast Approximate Anti-Aliasing) is a less GPU-intensive form of anti-aliasing compared to MSAA and can potentially improve FPS.
15. Should I use VSync on 144hz?
Whether you should use VSync on a 144Hz monitor depends on whether you experience screen tearing. If you do, VSync can help eliminate it, but it may also introduce input lag. Experiment to see what works best for you.
Final Thoughts
Choosing between fullscreen and borderless windowed mode involves a trade-off between performance and convenience. While fullscreen exclusive can offer a slight performance advantage, modern “fullscreen optimizations” have narrowed the gap, making borderless windowed mode a viable option for many gamers, especially those who value seamless multitasking and multi-monitor support. Ultimately, the best choice depends on your individual needs and preferences. Be sure to experiment with both modes to see which one works best for you and your system.
