Are your loading videos showing black area that should be transparent?

Are your videos of playfields washed out or looking grey?

Here's the proper nvidia control panel settings that you need to use.

Remember to do these changes ON EACH AND EVERY DISPLAY!!!

Also, make sure you're not running 10-bit HDR modes with TVs and your HDMI cable is rated for 4K if you have 4K

Most IMPORTANT!! If your playfield TV has a GAME MODE or PC MODE in the TV'S MENU(OPTIONS), make sure its set to that to reduce LAG as much as possible. During gameplay, its very important to try and minimize DISPLAY LAG when playing virtual pinball.

Stuttering and performance issues in emulators (such as Yuzu, PCSX2, Ryujinx) when using NVIDIA GPUs and OpenGL are frequently caused by the NVIDIA GeForce Experience Overlay or the new NVIDIA App Overlay. These overlays can introduce significant stutter, FPS drops, and mouse input lag.
Here are the solutions based on user reports and technical analysis:

1. Disable NVIDIA In-Game Overlay (Primary Fix)
Disabling the overlay is the most common and effective solution for stuttering, especially if you are not actively using Shadowplay to record.

Via GeForce Experience: Open GeForce Experience → Settings (gear icon) → General → Toggle In-Game Overlay to OFF.
Via New NVIDIA App: Open the app → Settings → Features → Overlay → Toggle OFF.
Note: If you want to keep recording capabilities, simply toggling “Instant Replay” off can sometimes help, but completely disabling the overlay is more reliable.

2. Optimize NVIDIA Control Panel (OpenGL Focus)
If the overlay is already off, configure the Control Panel to handle OpenGL better:
Open NVIDIA Control Panel → “Manage 3D Settings”.
OpenGL rendering GPU: Manually set this to your NVIDIA GPU (do not leave it on “Auto-select”).
Power management mode: Set to “Prefer maximum performance”.
Threaded optimization: If you have issues, try disabling this, although for most it should be on.
Vertical sync: Try setting this to “Use the 3D application setting” or “Off” in the panel, and handle it within the emulator instead.

3. Emulator Specific Settings
Vsync/Frame Pacing: Ensure Vsync is enabled in the emulator, but potentially disabled in the NVIDIA Control Panel to prevent conflicts.
Shader Backend: Using “Plain GLSL” is generally smoother than other options.
Force 60 FPS: If an emulator runs at 59.94 FPS, it might stutter on a 60Hz monitor. Force 60 FPS in the emulator's configuration file (e.g., PCSX2_VM.ini).
4. Other Potential Fixes
Disable Windows MPO (Multiplane Overlay): This can cause stuttering, especially with high refresh rate monitors.
RivaTuner Statistics Server (RTSS): Use RTSS to cap the framerate and enable “Scanline Sync” to fix stuttering.
Update/Reinstall Drivers: Use Display Driver Uninstaller (DDU) to remove old drivers and do a clean install.

If you are using the new NVIDIA App, it has been reported to cause up to 15% performance drops, making disabling its features crucial.
