GameLoop using too much RAM / high memory usage while playing CODM on PC

close-background-apps-and-browser-tabs-before-launching-gameloop (sortOrder=1, isMostHelpful)

Background applications compete directly with GameLoop for the same physical RAM — closing them before launching the emulator is the single most effective step on an 8 GB system.

1. Before opening GameLoop, close your web browser (Chrome, Edge, Firefox each keep 200–800 MB of RAM per window open). If you need Discord, use the web version in a tab instead of the desktop app — the desktop app uses 200–400 MB more than the site in a browser tab.
2. Open Task Manager (Ctrl+Shift+Esc) → Processes tab. Sort by Memory. Identify any process using more than 200 MB that you do not need during gaming (e.g., Spotify, OneDrive sync, Windows Search indexer, antivirus scheduled scans, update agents).
3. Right-click unnecessary high-memory processes → End task. Do this before launching GameLoop.
4. Disable startup apps that consume RAM passively: open Task Manager → Startup tab. Disable any non-essential app (e.g., OneDrive, Teams, Discord auto-launch, Steam, Epic Launcher). These will not launch at next boot and will not consume background RAM.
5. After closing background apps, launch GameLoop and then CODM. Check Task Manager's Performance → Memory view — you should see significantly more memory available than before.

Why this works: Windows manages physical RAM using a "use everything, page what is least-needed" approach. When GameLoop needs more RAM, Windows must evict other apps from physical RAM to disk (paging). This paging process causes the stuttering and slowdowns you experience. By closing background apps before launching GameLoop, you give the emulator a clear pool of physical RAM that it can fill without forcing Windows to page anything — eliminating the stutter caused by paging activity.

reduce-gameloop-graphics-settings-to-lower-vram-and-ram-usage (sortOrder=2)

Higher graphics settings in CODM cause the game to load larger textures and keep more rendering data in memory — reducing settings directly lowers both VRAM and RAM consumption.

1. Inside CODM (not GameLoop settings), open Settings → Audio & Graphics → Graphics.
2. Set Graphics Quality to Low or Medium. At High/Very High, CODM loads full-resolution texture atlases that consume significantly more RAM.
3. Set Frame Rate to Max 60 instead of Unlocked/Max 90+. Higher frame rate targets cause CODM to maintain a larger render buffer in memory to feed the renderer.
4. Disable Shadow Quality (set to Off or Low) — shadow maps are one of the larger memory consumers in CODM's renderer.
5. In GameLoop's own settings (the gear icon in GameLoop), set the emulator's rendering mode to Compatible or DirectX 9 (if available in your version) rather than DirectX 11/12 — the older rendering path allocates smaller GPU and system memory buffers.

Why this works: CODM scales its asset loading based on the configured graphics quality. At High or Very High settings, the engine pre-loads high-resolution texture mips and keeps them resident in GPU memory (VRAM) and system memory. On integrated graphics, VRAM is shared with system RAM, so high textures directly reduce available RAM. Lowering graphics settings tells the engine to load lower-resolution assets that are 30–60% smaller in memory, directly reducing peak RAM usage during a match.

reduce-gameloop-emulator-memory-allocation-in-settings (sortOrder=3)

GameLoop allocates a fixed amount of system RAM to the Android VM at startup — if this is set too high for your system, it leaves too little for Windows and other processes.

1. Close CODM and return to the GameLoop home screen (do not close GameLoop entirely yet).
2. Click the gear icon (⚙ Settings) in the top-right corner of GameLoop.
3. Navigate to Engines → Performance or Advanced Settings → Memory Allocation (the exact path varies by GameLoop version — look for a slider or dropdown labelled "RAM allocation", "VM memory", or "Engine memory").
4. If your PC has 8 GB of total RAM: set the GameLoop allocation to 3–4 GB maximum. If you have 16 GB: 6–8 GB is safe. Setting it above these values forces Windows to page, which causes stuttering.
5. Click Save/Apply and restart GameLoop completely (close via system tray → Exit, then relaunch). The new allocation takes effect at the next startup.

Why this works: GameLoop's Android VM requests its full memory allocation from Windows when the emulator starts. If the allocation exceeds what Windows can give from physical RAM, Windows must keep a portion of the VM's memory on disk (page file). Every time the VM accesses a page that is on disk, there is a 1–100 ms delay — the "stutter" you experience mid-match. By capping the allocation to what physically fits, you ensure the entire VM lives in physical RAM and there is no paging.

disable-gameloop-background-services-that-run-after-closing-gameloop (sortOrder=4)

GameLoop leaves several background service processes running even after you close the emulator — these hold 200–500 MB of RAM passively, which adds up if GameLoop is installed but not actively being used.

1. Open Task Manager → Processes. After closing GameLoop's main window (not via Exit, just the X button), check if any of these processes are still running: GameLoop.exe, GLS.exe, MobileGamePC.exe, GLHelper.exe, or any process with "GameLoop" or "Tencent" in the name.
2. If they are still running: right-click each → End task to reclaim the memory. For a full shutdown use the system tray icon (bottom-right clock area): right-click the GameLoop icon → Exit.
3. To prevent these services from auto-starting with Windows: press Win+R, type msconfig, go to the Services tab, check Hide all Microsoft services, then find and uncheck any GameLoop or Tencent service you don't want auto-starting. Click Apply (requires restart).
4. Alternatively, in Task Manager → Startup tab, find GameLoop or related Tencent entries and Disable them — they will still be usable when you manually launch GameLoop, they just won't auto-start at boot.

Why this works: GameLoop is designed to maintain background services for faster startup times and push notifications. These services keep portions of the emulator's runtime loaded in RAM even when you are not playing. On a PC with limited RAM, these passive services are "dead weight" — they hold memory that could be used by other applications. Killing them frees 200–500 MB immediately and prevents them from accumulating RAM consumption over the course of a Windows session.

restart-gameloop-mid-session-to-clear-memory-leak-after-long-play (sortOrder=5)

GameLoop's emulation layer has a gradual memory leak — over a long session (2+ hours), RAM usage can climb by 500 MB–1 GB above its normal level; a full restart of the emulator clears the leak.

1. If you notice CODM performance degrading after playing for more than 2 hours (more stuttering, slower menu loading, higher ping due to slow packet processing), check Task Manager — if GameLoop is consuming significantly more RAM than it did when you first launched, a memory leak has accumulated.
2. Exit CODM fully (return to the CODM main menu, then tap the back button to exit the game). Wait 30 seconds for any match data to save.
3. Close GameLoop completely: right-click the system tray icon → Exit. Confirm all GameLoop processes are gone in Task Manager.
4. Wait 30 seconds for Windows to reclaim the released memory (you will see "Available" memory in Task Manager → Performance → Memory increase).
5. Relaunch GameLoop and CODM. This fully resets the Android VM's memory state and clears any leaked allocations. Performance should return to the level it was at the start of your session.

Why this works: A memory leak means the emulator allocates memory for objects (match data, asset caches, render buffers) but does not always release that memory when the objects are no longer needed. Each match, lobby, or cutscene that loads and unloads assets can leave behind small unreleased allocations. Over many matches, these accumulate into hundreds of megabytes of "lost" RAM that the emulator holds but does not use — reducing the pool available for the current match. Fully restarting the emulator process terminates all allocations and starts fresh, eliminating the accumulated leak.
