PPSSPP Blur: Tips and Tricks to Improve Graphics Quality on PSP Emulator
How to Fix PPSSPP Blur on PC and Android
PPSSPP is a popular emulator that can run PlayStation Portable aka PSP games on computers, smartphones, and other devices. It offers many features and enhancements that make the games look better and run smoother than on the original PSP. However, some users may experience a blurry or pixelated graphics issue when playing PPSSPP games. This can ruin the gaming experience and make the games hard to enjoy.
Fortunately, there are some ways to fix PPSSPP blur and make the games look sharp and clear. In this article, we will show you how to fix PPSSPP blur on PC and Android devices, and explain why this problem occurs in the first place. Let's get started!
What is PPSSPP and Why Does It Blur?
PPSSPP is a PSP emulator for various platforms
PPSSPP is a free and open-source emulator that can run PSP games on Windows, Mac, Linux, Android, iOS, Nintendo Switch, and other platforms. It was created by Henrik Rydgård in 2012 and has since been improved by many contributors. PPSSPP can run most of the PSP games with high compatibility and performance. It can also upscale the graphics to higher resolutions, apply filters and shaders, save and load states, customize controls, and more.
PPSSPP is a great way to play PSP games on modern devices without having to buy a PSP console. You can enjoy classics like God of War, Grand Theft Auto, Naruto, Tekken, and many more on your PC or smartphone. You can also play multiplayer games with your friends using the online or local network features.
PPSSPP blur can be caused by different factors
While PPSSPP is a powerful emulator that can enhance the graphics of PSP games, it can also cause some issues like blurring or ghosting. This can happen due to various reasons, such as:
The original PSP games were designed to run at a low resolution of 480x272 pixels on a small screen. When they are upscaled to higher resolutions on larger screens, they can lose their sharpness and detail.
The graphics backend that PPSSPP uses to render the games can affect the quality of the output. Some backends like OpenGL or D3D9 may not support certain features or optimizations that can improve the graphics.
The graphics settings that PPSSPP uses to enhance the games can also have an impact on the blurring issue. Some settings like frameskipping, texture filtering, mipmapping, or post-processing effects can cause artifacts or distortions in the graphics.
The good news is that you can fix PPSSPP blur by changing some settings or options in the emulator. Depending on your device and game, you may need to try different combinations of settings to find the best one for you. Here are some tips on how to fix PPSSPP blur on PC and Android devices.
How to Fix PPSSPP Blur on PC
Change the graphics backend to Vulkan or D3D11
The first thing you should do to fix PPSSPP blur on PC is to change the graphics backend that PPSSPP uses to render the games. The graphics backend is the interface between PPSSPP and your graphics card or driver. It determines how well PPSSPP can use your hardware resources and features to improve the graphics.
There are four graphics backends available for PPSSPP on PC: Vulkan, D3D11, D 3D9, and OpenGL. Each backend has its own advantages and disadvantages, and some may work better than others for certain games or devices.
To change the graphics backend, you need to go to the Settings menu in PPSSPP, then select Graphics, then Backend. You can choose from the four options and see which one gives you the best results. Generally, Vulkan and D3D11 are the most recommended backends for PPSSPP on PC, as they support more features and optimizations than OpenGL or D3D9. However, some older or weaker graphics cards may not support Vulkan or D3D11, so you may need to use OpenGL or D3D9 instead.
After changing the graphics backend, you should also restart PPSSPP and the game to apply the changes. You may also need to adjust some other graphics settings to match the new backend.

Adjust the rendering resolution and screen scaling filter
The next thing you should do to fix PPSSPP blur on PC is to adjust the rendering resolution and screen scaling filter that PPSSPP uses to upscale the games. The rendering resolution is the internal resolution that PPSSPP uses to render the games before displaying them on your screen. The screen scaling filter is the algorithm that PPSSPP uses to scale the rendered image to fit your screen size.
To adjust the rendering resolution and screen scaling filter, you need to go to the Settings menu in PPSSPP, then select Graphics, then Rendering Resolution and Screen Scaling Filter. You can choose from different options for both settings and see which one gives you the best results. Generally, a higher rendering resolution will make the games look sharper and clearer, but it will also consume more resources and may cause slowdowns or crashes. A lower rendering resolution will make the games run faster and smoother, but it will also make them look blurrier or pixelated.
The screen scaling filter can also affect the quality of the upscaled image. Some filters like Linear or Bilinear will make the image smoother but also blurrier. Some filters like Nearest or Hybrid will make the image sharper but also more jagged. Some filters like xBRZ or SABR will try to enhance the image by adding more details and smoothing out the edges.
The best combination of rendering resolution and screen scaling filter will depend on your preference and device. You may need to experiment with different options to find the optimal balance between quality and performance.
Disable frameskipping and enable hardware transform
The last thing you should do to fix PPSSPP blur on PC is to disable frameskipping and enable hardware transform in PPSSPP. Frameskipping is a feature that allows PPSSPP to skip rendering some frames of the game to improve the speed and performance. Hardware transform is a feature that allows PPSSPP to use your graphics card to perform some calculations and transformations that are normally done by the PSP CPU.
To disable frameskipping and enable hardware transform, you need to go to the Settings menu in PPSSPP, then select Graphics, then Frameskipping and Hardware Transform. You can toggle both options on or off and see which one gives you the best results. Generally, disabling frameskipping will make the game look smoother and more consistent, but it may also cause lag or stuttering if your device is not powerful enough. Enabling hardware transform will make the game run faster and more stable, but it may also cause some graphical glitches or errors in some games.
The best combination of frameskipping and hardware transform will depend on your game and device. You may need to try different options to find the optimal balance between quality and performance.
How to Fix PPSSPP Blur on Android
Use the best graphics settings for your device
If you want to fix PPSSPP blur on Android devices, you need to use the best graphics settings for your device. Android devices have different specifications and capabilities, so you need to adjust the graphics settings according to your device's performance and compatibility. Some devices may be able to run PPSSPP games at high resolutions and settings, while others may need to lower them to avoid slowdowns or crashes.
To use the best graphics settings for your device, you can either use the default settings that PPSSPP provides for each game, or customize them yourself. To use the default settings, you need to go to the Settings menu in PPSSPP, then select Graphics, then Auto Frameskip. You can toggle this option on or off and see which one gives you the best results. Generally, enabling auto frameskip will make PPSSPP use the best settings for each game b
