Quick Fix Checklist (Try These First)

Before diving into deeper fixes, run through this 2-minute checklist:

• [ ] Update GameLoop — Settings → About → Check for Updates
• [ ] Run as Administrator — right-click GameLoop shortcut → Run as administrator
• [ ] Update GPU drivers — NVIDIA GeForce Experience / AMD Adrenalin / Intel Arc Control
• [ ] Disable antivirus temporarily — Windows Defender or third-party AV may be blocking GameLoop files

If none of these work, continue below.

Fix 1: Update GPU Drivers

Outdated GPU drivers are the #1 cause of GameLoop crashes, especially after Windows updates.

NVIDIA:

1. Open NVIDIA GeForce Experience (or download from nvidia.com/drivers)
2. Click Drivers tab → Check for Updates → Download → Express Installation
3. Reboot after installation

AMD:

1. Open AMD Adrenalin software (or download from amd.com/support)
2. Click Updates → Check Now → Install

Intel (integrated graphics):

1. Go to intel.com/support → search your processor → download the latest Graphics Driver
2. Or use Intel Driver & Support Assistant (auto-detects)

After driver update, reboot and relaunch GameLoop.

---

Fix 2: Switch Graphics Rendering Mode

GameLoop supports DirectX 11, DirectX 9, and OpenGL. A mismatch between your GPU's capability and GameLoop's selected mode causes crashes.

1. Open GameLoop → click the engine icon (top-right gear/settings) → Engine Settings
2. Under Rendering, switch from DirectX 11 to OpenGL (or vice versa)
3. Restart GameLoop

When to use each mode:

• DirectX 11: Best for most modern NVIDIA/AMD GPUs, Windows 10/11
• OpenGL: Better compatibility for Intel integrated graphics and older GPUs
• DirectX 9: Fallback for very old hardware (2010-era GPUs)

---

Fix 3: Enable Virtualization (VT-x / AMD-V)

GameLoop uses Android virtualization. If your CPU's virtualization extensions are disabled in BIOS, GameLoop crashes at startup or during engine initialization.

How to check if VT is enabled:

1. Open Task Manager → Performance tab → CPU
2. Look for "Virtualization: Enabled" at the bottom

How to enable if disabled:

1. Restart PC → enter BIOS (usually Del or F2 during boot)
2. Look for "Intel Virtualization Technology" (Intel) or "SVM Mode" (AMD)
3. Set to Enabled
4. Save and exit BIOS (F10)

Hyper-V conflict: If you use WSL2, Docker Desktop, or Windows Sandbox, Hyper-V may compete with GameLoop's virtualization layer.

To disable Hyper-V:

Run as Admin in Command Prompt:
bcdedit /set hypervisorlaunchtype off

Reboot. Retest GameLoop. (Note: this disables WSL2/Docker until you re-enable with hypervisorlaunchtype auto)

---

Fix 4: Run GameLoop as Administrator

Some crash scenarios involve GameLoop being denied access to system directories it needs.

1. Find the GameLoop shortcut on your desktop or in C:\Program Files\TxGameAssistant\AppMarket\
2. Right-click → Run as administrator
3. To make this permanent: right-click shortcut → Properties → Compatibility tab → check "Run this program as an administrator" → OK

---

Fix 5: Add GameLoop to Antivirus / Windows Defender Exclusions

Antivirus software (including Windows Defender) sometimes incorrectly flags GameLoop's virtualization files, deleting or quarantining them and causing crashes.

Windows Defender:

1. Search "Windows Security" → Virus & Threat Protection → Manage Settings
2. Scroll to Exclusions → Add or Remove Exclusions → Add an Exclusion → Folder
3. Add: C:\Program Files\TxGameAssistant\ and C:\Users\[YourName]\AppData\Local\Tencent\
4. Restart GameLoop

Third-party AV (Kaspersky, AVG, ESET, etc.):

• Add the same two folders as "trusted" or "excluded" paths
• Check your AV quarantine for any recently deleted GameLoop files and restore them

---

Fix 6: Check RAM Allocation

GameLoop's default RAM allocation is often too low for modern game sizes (especially CODM Season 7+, BGMI).

1. Open GameLoop → Engine Settings → Memory
2. Set memory to at least 4096 MB (4 GB); use 6144 MB if you have 16 GB system RAM
3. Restart GameLoop

Also check total system RAM usage: if your PC is already using 7+ GB when GameLoop opens, crashes are caused by memory exhaustion. Close Chrome tabs, Discord, or other background apps before launching.

---

Fix 7: Clear GameLoop Cache and Temporary Files

Corrupted cache files cause crashes and black screens.

1. Close GameLoop completely (including tray icon — right-click → Quit)
2. Open File Explorer → Navigate to C:\Users\[YourName]\AppData\Local\Tencent\
3. Delete the GameLoop folder (or just the cache subfolder inside it)
4. Also delete: C:\Program Files\TxGameAssistant\AppMarket\cache\
5. Relaunch GameLoop — it will rebuild the cache on startup

---

Fix 8: Reinstall the Game (Not GameLoop Itself)

If GameLoop itself launches but a specific game crashes, the problem is often a corrupted game installation.

1. In GameLoop → My Games → right-click the crashing game → Uninstall
2. Reinstall from GameLoop App Center
3. Launch and test

This is faster than reinstalling all of GameLoop and solves game-specific crashes that aren't related to the emulator engine.

---

Fix 9: Update Windows and DirectX

Outdated Windows or missing DirectX redistributables cause GameLoop crashes on some configurations.

Windows Update:

1. Settings → Windows Update → Check for Updates → Install all

DirectX End-User Runtime:

1. Go to microsoft.com → search "DirectX End-User Runtime Web Installer"
2. Download and run — installs DirectX 9.0c through 11 redistributables
3. Reboot

---

Fix 10: Increase Virtual Memory (Page File)

If you have 8 GB RAM or less, Windows may run out of virtual memory during gameplay, causing GameLoop to crash.

1. Search "Advanced system settings" → Advanced tab → Performance → Settings
2. Advanced tab → Virtual Memory → Change
3. Uncheck "Automatically manage paging file size for all drives"
4. Select C: drive → Custom size
5. Initial size: 4096 MB; Maximum size: 8192 MB
6. Click Set → OK → Reboot

---

Fix 11: Repair or Reinstall GameLoop

If none of the above work, reinstall GameLoop cleanly.

Repair first (faster):

• Control Panel → Programs → Tencent GameLoop → Repair (if available)

Full reinstall:

1. Uninstall GameLoop via Control Panel → Programs → Uninstall
2. Run a registry cleaner (CCleaner or Revo Uninstaller) to remove leftover entries
3. Delete any remaining folders: C:\Program Files\TxGameAssistant\, C:\Users\[YourName]\AppData\Local\Tencent\GameLoop\
4. Reboot
5. Download the latest GameLoop installer from gameloop.fun
6. Install to a drive with at least 10 GB free space

---

Fix 12: Check for Windows Compatibility Issues

Some Windows 11 security features conflict with GameLoop's virtualization.

Core Isolation / Memory Integrity:

1. Search "Windows Security" → Device Security → Core Isolation
2. If "Memory integrity" is ON, turn it OFF and reboot
3. Test GameLoop

Note: Turning off Memory Integrity reduces one layer of security. Re-enable it after testing if GameLoop doesn't need it to function.

Frequently Asked Questions

Why does GameLoop crash only in CODM and not other games? CODM (especially after season updates) has the highest memory footprint of any GameLoop title. Increase RAM allocation (Fix 6) to at least 4 GB, and check that your GPU drivers are up to date (Fix 1).

GameLoop crashes after 10-15 minutes of play — what's wrong? This is usually a thermal issue (GPU/CPU overheating) or memory leak. Check your PC temperatures using HWiNFO64 or MSI Afterburner. If temperatures exceed 90°C, clean your PC fans or add a cooling pad. Also try reducing in-game graphics from Ultra to High.

GameLoop says "Failed to start the engine" — what does that mean? The Android virtualization engine failed to initialize. This is almost always VT-x/AMD-V disabled in BIOS (Fix 3), or a Hyper-V conflict (also Fix 3).

Can GameLoop run on Windows 11? Yes, but Windows 11 Security features like Core Isolation / Memory Integrity can conflict. Try Fix 12 if other fixes don't work.

Does reinstalling GameLoop delete my game progress? No. Game progress for titles like CODM and BGMI is stored server-side (Activision/Krafton servers), not locally. After reinstalling GameLoop and the game, log back into your account and all progress is intact.

Is GameLoop safe to use in 2026? GameLoop (Tencent Gaming Buddy) is Tencent's official Android emulator for its titles. It's legitimate software, though like all Tencent software it has been scrutinized for data collection. Some players use a dedicated gaming PC or sandbox environment for emulators.

---

Summary

Most GameLoop crashes are solved by: updating GPU drivers (Fix 1), switching the graphics rendering mode (Fix 2), or enabling CPU virtualization in BIOS (Fix 3). For persistent crashes, increasing RAM allocation (Fix 6) and clearing cache (Fix 7) typically resolve the remaining cases.

Run through the fixes in order — most players resolve their crash in the first three steps.
