GameLoop PC Not Working in 2026 — Common Errors and Fixes

If GameLoop PC is not working, the failure almost always falls into one of five categories: installation and virtualization problems, game load failures, input problems, performance issues, or network and anti-cheat errors. This guide goes through each category with the fixes that actually work, in order of how often they appear.

Before you start: check the basics

Before running any fix, confirm these three things:

Your PC supports virtualization. GameLoop runs Android inside a virtual machine. If hardware virtualization is disabled in your BIOS, GameLoop cannot start any game. Check: open Task Manager → Performance → CPU. If "Virtualization: Enabled" appears, you're fine. If it says "Disabled", enter your BIOS (usually Del or F2 on startup), find "Intel VT-x" or "AMD SVM", and enable it.

You're not running Hyper-V. Hyper-V and GameLoop's virtualization layer conflict on older Windows versions. Open an Administrator Command Prompt and run bcdedit /set hypervisorlaunchtype off, then restart. On Windows 11 22H2+, GameLoop uses a Hyper-V compatible mode — check for a GameLoop update if you're on a recent build.

Your GPU drivers are current. Graphics-related crashes almost always trace to an outdated AMD or NVIDIA driver. AMD in particular releases driver updates that affect DirectX 11 compatibility (which GameLoop uses internally). Download directly from amd.com/support or nvidia.com/drivers.

GameLoop won't start at all

Symptom: Double-clicking GameLoop does nothing, or a splash screen appears briefly then closes.

Fix 1 — Run as Administrator. Right-click the GameLoop icon → "Run as administrator". GameLoop requires elevated permissions to launch its virtualization layer. If it works when run as administrator, set it permanently: right-click the icon → Properties → Compatibility → check "Run this program as an administrator".

Fix 2 — Clear the engine lock file. If GameLoop crashed previously, it may have left a lock file that prevents restart. Navigate to C:\Program Files\TxGameAssistant\AppMarket\ and delete any file named engine_lock or GameLoop.lock if present.

Fix 3 — Reinstall the runtime. Open the GameLoop folder → find VmEngine or AndroidCore subfolder → run the included Setup.exe or Repair.exe. This re-installs the virtual machine runtime without touching your game data.

Fix 4 — Antivirus exclusion. Some antivirus software (particularly Windows Defender with cloud protection enabled) flags GameLoop's virtualization processes as suspicious and kills them on launch. Add the entire C:\Program Files\TxGameAssistant\ folder as an exclusion in your antivirus before opening GameLoop.

Black screen when a game loads

Symptom: GameLoop opens, you launch a game, and the screen stays black. The game music may play, or there may be silence. After 30-60 seconds, GameLoop crashes or returns to the library.

Fix 1 — Switch the rendering engine. Open GameLoop Settings → Engine → switch between "Compatibility" and "Performance" modes. The Performance mode uses Vulkan-based rendering; Compatibility uses software rendering. If your GPU driver is slightly outdated, Compatibility mode often resolves black screens.

Fix 2 — Reduce the resolution. Go to GameLoop Settings → Display → set the emulator resolution to 1920×1080 or 1600×900. Some GPUs struggle with the default 2560×1440 GameLoop resolution on specific driver versions.

Fix 3 — Check VRAM. If you have a GPU with 2GB or less VRAM, black screens are common on games with high-resolution assets (CODM, PUBG Mobile, Genshin Impact). GameLoop targets 4GB minimum VRAM for these titles. Lowering texture quality in-game (if you can reach settings) or switching to Compatibility rendering mode are the workarounds on limited-VRAM GPUs.

Fix 4 — Grant storage permissions. Some game versions check for file access permissions on first load. Open GameLoop → Library → right-click the game → "File Manager" → confirm the game folder is not marked read-only. If it is, right-click the folder → Properties → uncheck "Read-only" → Apply to all subfolders.

Mouse and keyboard not working correctly

Symptom: The mouse cursor doesn't capture, keyboard bindings don't register in-game, or movement feels "disconnected" — like tapping rather than holding.

Fix 1 — Use the Keyboard Mapping editor. GameLoop's default key mapping covers common layouts, but game-specific mappings often need manual setup. Click the keyboard icon at the top of the GameLoop window while a game is running, then drag controls to match where you want them. If a control is not responding, it likely has no binding — add it by clicking the "+" button in the mapping panel.

Fix 2 — Enable mouse lock. For games like CODM and PUBG Mobile, the mouse should lock to the GameLoop window during play. If it keeps escaping: GameLoop Settings → Keyboard → enable "Lock mouse in window when game is running". The default toggle to release/capture the mouse is usually F12 — check your binding.

Fix 3 — Disable Windows mouse pointer enhancement. Windows adds pointer acceleration and "Enhance pointer precision" by default. These interfere with GameLoop's raw mouse input. Go to Windows Settings → Bluetooth & Devices → Mouse → Additional mouse settings → Pointer Options → uncheck "Enhance pointer precision".

Fix 4 — Reinstall GameLoop input driver. Open the GameLoop install folder → find DriverInstall or InputHelper → run the installer inside. This re-registers the HID driver that GameLoop uses to translate keyboard/mouse events into Android touch events.

FPS drops and stuttering

Symptom: The game runs but drops frames frequently, even on a capable PC. Or it runs at a fixed low FPS (30) that won't go higher.

Fix 1 — Set CPU cores and RAM correctly. GameLoop Settings → Engine → CPU Cores. Allocate 4 cores minimum for CODM and PUBG Mobile; 6 cores for Genshin Impact. Allocate 4GB RAM minimum. Under-provisioning is the most common cause of performance problems — GameLoop's defaults are conservative.

Fix 2 — Set Power Plan to High Performance. Windows 10/11 often runs on "Balanced" power by default, which throttles CPU clock speed to save power. Search "Power Plan" in Windows → select "High Performance" or "Ultimate Performance" (if available on your edition). If you're on a laptop, also go to GameLoop Settings → General → ensure it's using your discrete GPU, not integrated.

Fix 3 — Disable background CPU consumers. Game streaming software (OBS, XSplit), Discord overlay, and background Windows updates all compete for CPU time with GameLoop. During gameplay: close OBS capture if not needed, disable Discord's "Game Overlay" in Discord Settings → Overlay, and pause Windows Update in Settings → Windows Update → Pause Updates.

Fix 4 — Clear shader cache. GameLoop accumulates a shader cache over time. On some GPU drivers, this cache corrupts and causes intermittent stutters. Navigate to C:\Users\[username]\AppData\Local\Tencent\GameLoop\shaders\ and delete the contents (not the folder, just the files inside). GameLoop rebuilds the cache on next run — expect stutter only on the first few sessions.

Fix 5 — Unlock in-game FPS cap. Some games default to 30fps on first launch regardless of device performance. Inside CODM: Settings → Graphics → set Frame Rate to "Max" or "Ultra". Inside PUBG Mobile: Settings → Graphics → Frame Rate → "Ultra" (if your account qualifies). GameLoop itself cannot override the in-game cap — you must change it inside the game's own settings.

Anti-cheat errors and game bans

Symptom: The game launches, then immediately closes with an error about "unauthorized software", "cheat detected", or "system modification". Or your account receives a ban notification.

Context first: GameLoop is published by Tencent (the same company that publishes CODM, PUBG Mobile, and many other titles), which means the official GameLoop emulator is explicitly whitelisted in these games' anti-cheat systems. If you are using the official GameLoop build from gameloop.com, you should not be flagged by the anti-cheat in Tencent games. The errors below have specific causes that are NOT "emulator detection".

Fix 1 — You're using a modified GameLoop. Third-party "GameLoop Pro", "GameLoop Ultra", and similar rebranded versions exist that are not from Tencent. These are not whitelisted and will trigger anti-cheat. Uninstall completely and reinstall from gameloop.com.

Fix 2 — Virtual machine detection by non-Tencent anti-cheat. Games using anti-cheat systems like EasyAntiCheat (EAC) or BattlEye block virtual machine environments entirely. This includes Fortnite Mobile (if applicable in your region), and any other non-Tencent game that uses these systems. There is no fix — these games are incompatible with GameLoop and any emulator that uses a virtual machine layer.

Fix 3 — Macro or auto-clicker software. If you have Logitech G Hub, Razer Synapse, or SteelSeries GG running with scripting enabled, CODM's anti-cheat (Hyperion) will flag it as macro-assisted input. Disable all game-specific macros and scripts in peripheral software before running CODM via GameLoop.

Fix 4 — Account violation (not a GameLoop issue). If you received a ban and play legitimately, contact the game's support team directly. GameLoop does not issue bans — the game's own servers do. Support links: CODM at support.activision.com/codmobile, PUBG Mobile at support.pubg.com.

Network errors and high ping

Symptom: "Connection lost", frequent disconnects mid-match, or ping that shows 200ms+ in a region that should be closer.

Fix 1 — Use a wired connection. GameLoop's virtual network adapter adds latency on top of your existing connection. Wi-Fi with a wireless-adapter → virtual adapter chain is the worst-case path. Ethernet cuts 20–40ms off typical Wi-Fi latency.

Fix 2 — Change DNS. GameLoop's virtual network adapter uses your system DNS by default, which may be slow on some ISPs. Try switching to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) via Windows network settings → Change Adapter Settings → your network adapter → IPv4 Properties.

Fix 3 — Select the correct server region. In CODM, the game selects your region at first login. If you created your account while traveling or via VPN, the region may be wrong. Check: CODM → Settings → Account → Server Region. Changing server region resets your ranked data — check before doing this.

Fix 4 — Disable GameLoop VPN. Some GameLoop versions ship with a built-in "Network Booster" or VPN feature that routes game traffic differently. If enabled, disable it: GameLoop Settings → Network → disable "Accelerate game network" or similar toggle. In many cases this adds latency rather than reducing it.

Voice chat not working

Symptom: Other players cannot hear you, or you cannot hear them, when using voice chat inside a game running on GameLoop.

Fix 1 — Grant microphone permission. GameLoop needs Windows microphone permission. Open Windows Settings → Privacy & Security → Microphone → enable "Let apps access your microphone" AND find GameLoop in the list below and enable it individually.

Fix 2 — Set the correct audio device in GameLoop. GameLoop Settings → Sound → select your headset microphone explicitly (not "Default" or "Communication Device" — pick the specific device name). If you have multiple audio devices, "Default" can pick the wrong one.

Fix 3 — Enable the virtual speaker. Some GameLoop installations include a "TxGameAssistant Audio" virtual speaker. If your game audio is routed through this but your physical speakers aren't listening to it, you'll get no sound. Open Windows Sound Settings → Playback → ensure your actual headset/speakers are set as the default device, not the virtual one.

Quick diagnostic table

Error	Most likely cause	First fix to try
GameLoop doesn't start	Virtualization disabled	Enable VT-x/SVM in BIOS
Black screen on game load	Rendering engine conflict	Switch to Compatibility mode
Game crashes mid-match	Driver or VRAM issue	Update GPU driver
Mouse won't capture	Missing mouse-lock setting	Enable "lock mouse in window"
FPS stuck at 30	In-game cap not set	Raise frame rate in game settings
Anti-cheat block	Modified GameLoop or macro software	Reinstall from gameloop.com; disable macros
High ping	Wi-Fi + virtual adapter overhead	Use Ethernet; disable network booster
No voice	Missing microphone permission	Grant mic access in Windows Privacy

If none of these work

A full reinstall resolves the majority of persistent GameLoop issues. The correct procedure:

Uninstall GameLoop via Windows Settings → Apps → GameLoop → Uninstall
After uninstall, manually delete C:\Program Files\TxGameAssistant\ if it still exists
Delete C:\Users\[username]\AppData\Local\Tencent\GameLoop\ (this contains settings and caches, not game files — game installs are stored separately)
Restart Windows
Download a fresh GameLoop installer from gameloop.com (not a mirror)
Install and launch — the wizard re-detects your hardware and sets defaults

Game data is typically stored at C:\ProgramData\TxGameAssistant\ and survives the reinstall. CODM and PUBG Mobile do not need to be re-downloaded, only GameLoop itself.
