Features AetherSX2 Emulator

Platform support

AetherSX2 Emulator supports almost all platforms such as Android, iOS, Windows, Mac, and Linux, provided that the platform uses ARM64 architecture.

Supports modern controllers

AetherSX2 supports gamepad controllers for easier playing; it also supports USB and Bluetooth connections. But you have to adjust the controller settings in the controller settings menu.

Graphics

AetherSX2 has quite complete and efficient graphic support features according to your device's needs, here are some GPU renderers in aetherSX2 :

  • OpenGL : tends to be more compatible with a wider range of Android devices than other backends, such as Vulkan, especially on devices with older GPUs or less Vulkan support.
  • Vulkan : the Vulkan driver in AetherSX2 APK is designed to optimize the capabilities of powerful hardware, especially on multi-core processors and the latest GPUs. Vulkan produces more stable and smooth graphic output in complex games or forces the game to be stable in the user experience so as not to experience crash, lag, and glitch problems.
  • Software : this is a driver provided by AetherSX2 to overcome if Vulkan and OpenGL graphic rendering are not supported on your device. this is a solution that can be used, but this driver is sometimes experiencing poor performance.

Resolution Scaling 8X

AetherSX2 supports the resolution scale feature, which functions to double the internal resolution used to render PS2 Emulator game graphics. The standard PS2 resolution is usually around 513x447 pixels or lower, depending on the game that supports the display mode (interlaced or progressive).

With this feature, AetherSX2 APK allows users to force increase the internal resolution up to 8 times the native resolution of the PS2, this can significantly improve visual sharpness and clarity.

Bilinear filtering

Bilinear filtering in AetherSX2 apk is an important feature by improving the graphic quality of PS2 games running on the aethersx2 emulator. This feature smooths the texture of images or videos, reduces the repixel effect, and makes the display smoother.

  • Nearest-Neighbor (Point): a texture filtering method that maintains the original pixel appearance of PS2 games without interpolation or blur effects. This method is very useful for users who want optimal performance or a retro-style visual appearance.
  • Bilinear (Forced): Full smoothing, smoother images but can be a little blurry.
  • Bilinear (PS2): makes smoothing similar to the PS2 console to the aethersx2 emulator, between smooth and sharp balanced.
  • Bilinear (Forced Excluding Sprite): Image smoothing, except for 2D objects (sprites), still provides sharpness.

Mipmapping

Mipmapping is one of the features of the AetherSX2 emulator to improve the graphic quality of PS2 games. AetherSX2 uses a low-resolution image texture mechanism to minimize repixels and flickering when the image object is viewed from a distance.

Some Mipmapping Options in AetherSX2

  • Automatic (Default): AetherSX2 APK automatically adjusts the type of mipmapping that suits the game.
  • Disabled: Mipmapping is disabled, improving graphics performance but sacrificing smoothness of the graphics image.
  • Basic (Create Mip): AetherSX2 APK creates its own customized version of the mipmap.
  • Full (PS2 Mip): Aethersx2 Uses the mipmap provided by the original PS2 console, which offers the best graphics performance.

Mipmapping improves graphical fidelity, although it can affect graphical performance. Use the option that best suits your device's capabilities.

Trilinear Filtering

Trilinear Filtering is used to improve the quality of graphic textures in AetherSX2 apk. This feature works to smooth textures in three dimensions, reducing unused visual artifacts and blurring in the image, especially on distant and small image objects.

Trilinear Filtering Options:

  • Automatic (Default): Aethersx2 apk automatically adjusts the use of trilinear filtering, balancing image quality and performance.
  • Disabled (Off): If you enable the Trilinear Filtering feature (Off), it will increase graphics performance at the expense of texture smoothness.
  • Enabled (PS2): This feature imitates the trilinear filtering of the pure PS2 console, aethersx2 apk uses an authentic PS2 visual representation.
  • Enabled (Forced): This feature will force Trilinear Filtering to always be applied, providing smoother images but using high hardware performance power.

Trilinear filtering in AetherSX2 APK is one of the useful features for improving graphics performance, it offers smoother and more realistic image texture quality.

Anisotropic Filtering (AF)

Anisotropic filtering is one of the aethersx2 features to fix the texture of the oblique angle on the graphics so that the display is sharper and more realistic. This feature fixes the texture displayed by making a lot of data processing from the direction of the viewpoint seen by the aethersx2 player. activating this feature means that the GPU performance load will increase so adjust it to your device specifications.

Anisotropic Filtering Options in AetherSX2 APK:

  • Disabled (Default): By disabling this feature, AetherSX2 will use the default texture filtering from PS2.
  • 2x, 4x, 8x, 16x: The greater the value of the anisotropic filtering level selected, the sharper the texture will be. adjust the value according to your device because the higher the value, the more GPU usage.

How to Optimize AetherSX2 Performance

Get the best performance out of the emulator with these simple settings.

GPU Rendering

You should set the graphics renderer in the aethersx2 emulator settings, to optimize the hardware and aethersx2.

  • For Snapdragon:
    we recommend using the OpenGL graphics renderer on Snapdragon devices as it has proven to be more optimal on Andreno GPU.
  • For Mediatek:
    For devices with mediatek processors, we recommend using the Vulkan graphics renderer, which has been proven to be more optimal and maximal on Mali GPU.

Enable Multi-Threaded VU

We recommend enabling Multi-Threaded VU, which improves the performance of all multi-core CPUs.
