GameLoop dedicated GPU — how to force your NVIDIA or AMD card

Open Task Manager, click the Performance tab, and watch the GPU readings while GameLoop runs. If the GPU listed first — usually GPU 0, the integrated Intel or AMD Radeon graphics — is working hard, and GPU 1 (your discrete NVIDIA or Radeon card) is idle or near-idle, GameLoop is running on the wrong GPU.

This is the default behaviour on any laptop or desktop with hybrid graphics. Windows assigns low-power applications to the integrated chip to save battery and heat; GameLoop does not automatically override that. The game still launches and plays, but at integrated-graphics performance levels rather than what the discrete card can deliver.

The fix is a per-application GPU preference, set in one of three places depending on your hardware.

Step one: confirm which GPU is actually running

Before changing anything, confirm the problem is real.

Open Task Manager → Performance tab → scroll down to your GPU entries. You will see GPU 0 and, if you have a second card, GPU 1. The label next to each one shows the manufacturer and model.

While GameLoop is running and a game is loaded, look at the 3D or Copy engine bars on each GPU. The one doing work is the one GameLoop is using.

If GPU 0 is an Intel or integrated AMD chip and it is the active one, continue below. If your discrete card is already showing activity, the problem is elsewhere — see the renderer section of the high-CPU article instead.

Fix 1 — Windows Graphics Settings (works for both NVIDIA and AMD)

This method works on Windows 10 and Windows 11, regardless of GPU brand. It is the simplest fix and the one most players should try first.

Windows 11:

1. Open Settings → System → Display → Graphics
2. Click Browse and navigate to the GameLoop executable. It is typically at:

C:\Program Files\TxGameAssistant\AppMarket\GameLoop.exe On some installs the path is C:\Program Files\GameLoop\GameLoop.exe — use the one that exists on your machine.

1. Once added to the list, click the app entry and select Options.
2. Choose High performance and click Save.

Windows 10:

1. Open Settings → System → Display, then scroll to the bottom and click Graphics settings.
2. Under "Choose an app to set preference", select Desktop app from the dropdown.
3. Click Browse and locate GameLoop.exe as described above.
4. Click Options, select High performance, and save.

Restart GameLoop after saving. The OS will now route it to the discrete card on the next launch.

Fix 2 — NVIDIA Control Panel (NVIDIA cards only, more control)

If you have an NVIDIA card and want per-process control beyond what Windows Settings offers, the NVIDIA Control Panel gives you a direct rule.

1. Right-click the desktop and open NVIDIA Control Panel (if it is not visible, find it in the Start menu or Windows Settings under Display adapters).
2. In the left panel, go to Manage 3D settings → Program Settings.
3. Click Add and locate GameLoop.exe. If GameLoop is not in the list, click Browse and find it manually at the path listed in Fix 1.
4. Under "Select the preferred graphics processor for this program", choose High-performance NVIDIA processor.
5. Click Apply.

The change takes effect the next time GameLoop opens. No restart required, but close and relaunch GameLoop.

You can verify it worked immediately: in NVIDIA Control Panel, the GPU activity indicator for GameLoop should appear under the NVIDIA card, not under the display GPU.

Fix 3 — AMD Radeon Software (AMD discrete cards only)

1. Right-click the desktop and open AMD Radeon Software (or search for it in the Start menu).
2. Go to Gaming → Add a Game. If GameLoop is not already in your game list, click Add and browse to GameLoop.exe.
3. Once added, click the GameLoop entry to open its profile.
4. Under Graphics, find the GPU workload or Graphics profile setting and set it to your discrete Radeon card. The exact label depends on your driver version; look for any setting that references "discrete" or "high performance" as opposed to "power saving" or "integrated."
5. Save and relaunch GameLoop.

After the fix: what to expect

After setting the GPU preference and relaunching GameLoop, go back to Task Manager and watch the GPU readings again. You should see:

• GPU 1 (discrete): 3D activity present while a game is loaded
• GPU 0 (integrated): near-zero or idle during gameplay

Frame rates in-game will improve in proportion to how large the gap is between your integrated and discrete GPU. On a mid-range laptop — say, a Core i5 with an integrated GPU versus a dedicated RTX 3050 — the difference is typically 1.5× to 2× the frame rate at the same settings.

The gain is larger when running at higher resolutions or with better graphics settings in GameLoop. If you were previously locked to 30 fps to keep the game stable, try 60 fps after the fix.

What does not help

If after all three fixes the discrete GPU still does not show activity during GameLoop, the remaining cause is usually one of two things: the laptop's BIOS has the discrete card disabled in a power-saving firmware profile, or the display is physically wired to the integrated GPU only (common on many laptop designs), which means the rendered frames still pass through the iGPU before appearing on screen even if the discrete card did the work. Both are hardware-level constraints that settings cannot override.

For most players on a standard desktop or a laptop without BIOS-level GPU disabling, one of the three fixes above will move GameLoop to the right card.
