What are the features of aethersx2?
Support
Aethersx2 Emulator Supports Almost All Platforms such as Android, IOS, Windows, MAC and Linux provided that the platform uses arm64 architecture.
Controller
Aethersx2 supports game pad controller for easier playing, it also supports usb and bluetooth connection. 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 : designed to take full advantage of hardware capabilities, especially on modern multi-core processors and GPUs. Vulkan often provides more stable results in complex or demanding games compared to other backends. Certain games that may struggle with OpenGL tend to run smoother on Vulkan.
- Software : used for maximum accuracy when Vulkan or OpenGL has rendering issues, although the performance is much heavier because it uses the CPU instead of the GPU.
Resolution Scaling 8X
Resolution Scaling in AetherSX2 refers to the internal resolution multiplier used to render PS2 game graphics. The native resolution of the PS2 is typically around 512x448 pixels or lower, depending on the game and display mode (interlaced or progressive). With this feature, AetherSX2 allows users to increase the internal resolution up to 8 times the original resolution, which significantly enhances visual sharpness and clarity.
Bilinear filtering
Bilinear filtering in AetherSX2 is an important feature to improve the visual quality of PlayStation 2 games run on Android devices. This feature works by smoothing image textures, reducing pixelation effects, and creating a smoother display.
- Nearest-Neighbor (Point): Without smoothing, the image is sharp but rough.
- Bilinear (Forced): Full smoothing, the image is smoother but can be slightly blurry.
- Bilinear (PS2): Mimics the original PS2 smoothing, balanced between smooth and sharp.
- Bilinear (Forced Excluding Sprite): Smoothing, except for 2D objects (sprites), maintaining their sharpness."
Mipmapping
Mipmapping is a feature in the AetherSX2 emulator to enhance the visual quality of PlayStation 2 games. It utilizes lower-resolution versions of image textures to minimize pixelation and flickering when objects are viewed at a distance.
Mipmapping Options in AetherSX2:
- Automatic (Default): The emulator automatically selects the appropriate mipmapping type.
- Off: Mipmapping is disabled, improving performance but reducing graphic smoothness.
- Basic (Generate Mips): The emulator generates its own mipmaps.
- Full (PS2 Mips): Uses mipmaps provided by the original PS2 game, offering the best graphics.
Mipmapping improves graphic fidelity, though it might impact performance. Choose the option that best suits your device's capabilities.
Trilinear Filtering
Trilinear Filtering enhances texture quality in AetherSX2, the PS2 emulator. This technique smooths textures in three dimensions, reducing visual artifacts and blurriness, especially on distant objects.
Trilinear Filtering Options:
- Automatic (Default): The emulator automatically adjusts trilinear filtering usage, balancing quality and performance.
- Disabled (Off): Trilinear filtering is deactivated, boosting performance at the cost of texture smoothness.
- Enabled (PS2): Mimics the original PS2 trilinear filtering, providing authentic visual representation.
- Enabled (Forced): Trilinear filtering is forcefully applied, yielding smoother images but demanding more device resources.
Trilinear filtering in AetherSX2 is a crucial feature for graphic enhancement, offering smoother and more realistic texture quality. With options like Automatic, Disabled, PS2, or Forced, users can tailor their visual experience as needed. Remember, device performance should be considered when enabling this feature.
Anisotropic Filtering
Anisotropic Filtering is a texture filtering technique that enhances image quality, especially when textures are viewed at oblique angles. It reduces blurriness and preserves texture detail, resulting in a sharper and more realistic display in PS2 games emulated on AetherSX2.
Anisotropic Filtering Options in AetherSX2:
- Disabled (Default): This feature is deactivated, using basic texture filtering.
- 2x, 4x, 8x, 16x: Anisotropic filtering levels, increasing texture sharpness. The higher the value, the better the quality, but also the greater the burden on the device.
