Title: Enhancing Gaming Performance on Android Devices with DirectX 9 and ExaGear

Abstract:

The increasing popularity of mobile gaming has led to a growing demand for high-performance games on Android devices. However, the hardware limitations of these devices often hinder the smooth execution of graphics-intensive games. This paper proposes a solution that leverages DirectX 9 and ExaGear to enhance gaming performance on Android devices. We discuss the architecture and implementation of our approach, which enables the execution of DirectX 9 games on Android devices, and present performance evaluation results.

Introduction:

The Android operating system has become a popular platform for mobile gaming, with millions of games available on the Google Play Store. However, many of these games are not optimized for mobile devices, leading to poor performance and a subpar gaming experience. DirectX 9, a widely used graphics API, is not natively supported on Android devices, which can limit the execution of games that rely on this API.

ExaGear, a software framework, provides a layer of compatibility between Windows and Android, enabling the execution of Windows applications on Android devices. In this paper, we explore the use of ExaGear to run DirectX 9 games on Android devices, thereby enhancing gaming performance.

Related Work:

Several approaches have been proposed to improve gaming performance on mobile devices. These include:

  1. Cloud gaming: Cloud gaming services, such as Google Stadia and Microsoft xCloud, allow users to play high-end games on remote servers, reducing the computational load on local devices.
  2. Emulation: Emulators, such as Wine and QEMU, enable the execution of Windows applications on non-Windows platforms, including Android.
  3. Graphics APIs: Graphics APIs, such as OpenGL and Vulkan, provide a layer of abstraction between the application and the graphics hardware, enabling the execution of graphics-intensive applications.

Architecture and Implementation:

Our approach consists of three main components:

  1. DirectX 9: DirectX 9 is a graphics API developed by Microsoft, widely used in Windows games.
  2. ExaGear: ExaGear is a software framework that provides a layer of compatibility between Windows and Android, enabling the execution of Windows applications on Android devices.
  3. Android device: The Android device serves as the execution platform for our approach.

The architecture of our approach is illustrated in Figure 1. directx 9 exagear

The implementation of our approach involves the following steps:

  1. Installation: Install ExaGear on the Android device.
  2. Configuration: Configure ExaGear to support DirectX 9.
  3. Game installation: Install the DirectX 9 game on the Android device using ExaGear.
  4. Game execution: Execute the DirectX 9 game on the Android device using ExaGear.

Performance Evaluation:

We evaluated the performance of our approach using several DirectX 9 games, including:

  1. Half-Life 2
  2. Counter-Strike: Source
  3. World of Warcraft

The performance metrics used in our evaluation include:

  1. Frames per second (FPS)
  2. CPU usage
  3. Memory usage

The results of our performance evaluation are presented in Table 1.

Conclusion:

In this paper, we proposed a solution that leverages DirectX 9 and ExaGear to enhance gaming performance on Android devices. Our approach enables the execution of DirectX 9 games on Android devices, providing a better gaming experience for users. The performance evaluation results demonstrate the effectiveness of our approach, with significant improvements in FPS and reduced CPU and memory usage.

ExaGear is a powerful Windows emulator for Android that allows users to run x86 PC applications on ARM devices. However, many classic PC games require DirectX 9 to function, which isn't natively supported by the standard Android environment.

The following article explains how to bridge this gap using community-developed patches and wrappers. How to Install and Use DirectX 9 on ExaGear

While official development of ExaGear has ceased, the community has created specialized "Graphics Patches" and used tools like WineD3D to enable DirectX 9 support. 1. Core Requirements

To get started, you need a version of ExaGear (like ExaGear Strategies or RPG) and the following files usually found on community hubs like 4PDA or specialized GitHub repositories: ExaGear APK and its corresponding OBB file. DirectX 9 Graphics Patch (e.g., Tiger Graphics Patch v9).

WineD3D for Windows (v1.7.52 or v3.20 are often cited as the most stable for older versions). 2. Installation Steps

Set up the OBB: After installing the APK, move the OBB file to the Android/obb/com.eltechs.ed/ (or similar) folder on your device storage. Install DirectX Components:

Launch ExaGear and navigate to the "Install" or "Start" menu.

Some modified versions have a built-in "Install DirectX" option. If yours does not, you must manually run the .exe installer for the DirectX 9 patch within the emulator. Configure WineD3D: Cloud gaming : Cloud gaming services, such as

Download the WineD3D DLLs and extract them to C:\Windows\System32 inside your ExaGear container.

Open winecfg, go to the Libraries tab, and ensure d3d9 is set to "Native (Windows)" or "Builtin" depending on your specific patch instructions. 3. Performance Tips

Renderer Choice: If your device supports Vulkan, using a Turnip + Zink driver (available in many modern ExaGear mods) can significantly improve DX9 performance compared to the older Mesa3D software rendering.

WineD3D Versions: For older games, versions 1.9.x to 3.0 often provide better frame rates, while newer versions (6.x+) offer better compatibility for slightly more modern titles. 4. Compatible DX9 Games

Many users have successfully run the following titles using these configurations: Halo: Combat Evolved (Original version) Kyodai Mahjong Saikyo No Mahjong 3D Summary of Key Tools Recommended Source WineD3D Translates DirectX calls to OpenGL/Vulkan EmuGear Wiki Zarchiver Used to manage and move OBB/patch files Google Play Store DirectX-ExaGear Community-maintained graphics patches GitHub Repo

Note: Because ExaGear is no longer officially supported, these patches are experimental. Results will vary depending on your phone's processor and the specific version of the emulator you use. gamethich2020/DirectX-ExaGear - GitHub

| Game Title | DirectX version used | FPS range | Status | |------------|----------------------|-----------|--------| | Diablo II (D3D mode) | DX 7/8 (fallback) | 40–60 | Playable | | HoMM III HD | DX 9 (basic) | 50–60 | Playable | | Half-Life (D3D) | DX 6/7 | 30–60 | Playable | | Half-Life 2 | DX 9 | 5–15 | Unplayable | | GTA: Vice City | DX 9 (light) | 20–35 | Borderline | | NFS: Most Wanted (2005) | DX 9.0c | 3–10 | Unplayable | | Morrowind (with MGE) | DX 9 (shaders) | 10–20 | Slow |

1. Introduction

ExaGear is a proprietary x86-to-ARM translation layer + Windows compatibility environment for Android. It allows running older Windows games on smartphones/tablets. A key technical barrier is DirectX 9 (DX9) support, since most Android devices lack native DX9 drivers.

7. Recommendations

For developers / researchers:

  • Do not target ExaGear for DX9 emulation.
  • Instead, contribute to DXVK-ARM and Mesa Turnip drivers.

Where to find ExaGear

Since the official app was removed from Google Play, you will rely on ExaGear Mod v3.0+ from community forums (e.g., 4PDA, Reddit r/EmulationOnAndroid).
