Customer Story: Running 3 Instances of Last War Survival Game on a K620 GPU Server

I am an individual user who runs multiple instances of Last War: Survival using the BlueStacks Android emulator. Since BlueStacks relies on GPU acceleration and OpenGL support for stable performance—especially when running several game instances simultaneously—I required a dedicated server equipped with a compatible GPU. This setup ensures that each game instance runs smoothly, enabling me to automate base building, resource collection, and account management around the clock without lag or interruption..

Application Scenario

This case demonstrates the deployment of Last War: Survival—a popular mobile strategy game—on a dedicated server powered by an Nvidia Quadro K620 GPU. The user utilized the BlueStacks Android emulator to successfully run and manage three concurrent game instances.

Last War: Survival combines base building, resource management, and real-time combat mechanics, making it highly suitable for automation. By leveraging in-game scripts, the user fully automated tasks such as construction, resource farming, and account progression—achieving continuous 24/7 operation without manual intervention.

This example showcases how GPU-accelerated virtualization enables scalable mobile game automation. It’s an ideal solution for users managing multiple accounts or seeking efficient background farming. It also underscores the stability and performance advantages of running Android emulators like BlueStacks on dedicated server hardware.

Server Specifications

✅ CPU: Intel Xeon E3-1270v3 (Quad-Core)
✅ RAM: 16GB
✅ Storage: 120GB + 960GB SSD
✅ Bandwidth: 100Mbps
✅ OS: Windows 10 Pro
✅ GPU: Nvidia Quadro K620 (2GB Vram)

Deployment Process

Login to the Server & Check GPU Driver

  • Once you choose a K620 GPU server from DBM, the latest official NVIDIA Quadro K620 driver is pre-installed, saving you time on initial GPU configuration.
  • Ensure the GPU is properly detected in the Device Manager.

Install BlueStacks Emulator

  • Visit the BlueStacks official site and download the latest version (preferably BlueStacks 5 or X).
  • During installation, allocate sufficient CPU cores and memory for better performance.

Optimize BlueStacks Settings

  • Set the graphics mode to “Compatible” or “Performance” based on stability.
  • Allocate at least 1 CPU cores and 2GB RAM (2 cores and 4GB+ recommended for smoother gameplay).

Install and Launch the Game

  • Open the Google Play Store inside BlueStacks, search for Last War: Survival, and install the game.
  • Launch the game and follow the in-game prompts. Initial loading may take some time.

Import or Record Auto-Play Script (AFK/Idle Mode)

  • Use the BlueStacks Macro Recorder to record repetitive in-game actions such as resource collection or auto-combat.
  • Alternatively, import pre-made macro scripts compatible with Last War to automate tasks and support AFK gameplay.
  • Adjust the loop interval and timing as needed to avoid detection and ensure smooth automation.

Network Configuration (Optional)

  • Make sure the server has a stable internet connection and can access Google services.
  • If Play Store is restricted in your region, consider installing the APK manually or using a VPN.

Reliability Evaluation

Running Last War: Survival on BlueStacks using a server equipped with the NVIDIA Quadro K620 GPU demonstrates stable and consistent performance for general gameplay and AFK (idle) sessions. While the K620 is an entry-level workstation GPU, it supports hardware acceleration well enough for lightweight Android emulation. Under optimized conditions—such as disabling Windows updates, allocating sufficient resources, and reducing background activity—users can expect reliable uptime with minimal crashes or interruptions. However, for more graphically demanding gameplay scenarios, or if multitasking with multiple instances, performance may be limited. Overall, the setup is well-suited for AFK grinding and basic interaction within the game.

🍞 Bread: 25.9K
💰 Metal: 1.8K
🪙 Coins: 2.7K

Optimization Tips

Disable Ads and Pop-ups

  • Avoid optional in-game ads or video rewards to reduce interruptions and save system resources.

Turn Off Windows Automatic Updates

Prevent unexpected reboots during long AFK sessions:

  • Run services.msc
  • Find Windows Update → Set Startup Type to "Disabled" or "Manual"

Close Unnecessary Background Apps

  • Shut down Chrome, OneDrive, Steam, or any unused applications to free up CPU and RAM.

Disable Background Sync and Suggestions in BlueStacks

  • Turn off “Background sync,” “App store recommendations,” and similar features under Settings.

Clear BlueStacks Cache Periodically

  • Helps avoid lag after prolonged use. Use the internal cleanup option under BlueStacks settings.

Conclusion & Recommendations

Based on my experience, the Express GPU Dedicated Server – P1000 fully meets the requirements for running up to 6 concurrent instances of LDPlayer with automated gameplay scripts for AFK Arena. The server handles the game’s daily tasks—including auto-battling, summoning, and collecting rewards—smoothly.
For use cases like game automation, Android emulator testing, or GPU-light workloads, this setup proves to be both cost-effective and reliable.
