This page checks whether your browser can use hardware-accelerated WebGL, which is important for smooth performance in ArcGIS Experience Builder apps like the
GeoNB Map Viewer.

How to Interpret Your Results
This test helps identify why some computers may have difficulty loading the GeoNB Map Viewer (Experience Builder). Use the guide below to understand your result:
🟢 Excellent (40+ FPS) — Hardware-accelerated WebGL 2.0 is active and should perform well.
🟡 Moderate (20–39 FPS) — Performance may be slow. Update your browser and graphics drivers.
🔴 Poor (<20 FPS) — The Experience Builder viewer may freeze or fail. Use the GeoNB Map Viewer Lite.
⚠️ WebGL 2.0 not supported — Only WebGL 1.0 is available; some layers may not display correctly. Use the GeoNB Map Viewer Lite.
⚠️ Outdated DirectX (Direct3D9 / Shader Model 3.0) — Very old GPU/driver path. Update drivers or try Edge/Firefox. Use the GeoNB Map Viewer Lite if issues continue.
⚠️ DirectX 10 (Shader Model 4.0) — GPU too old for WebGL 2.0 even if FPS is high. Use the GeoNB Map Viewer Lite.
⚠️ Software rendering (SwiftShader/LLVMpipe) — GPU acceleration disabled; enable hardware acceleration or update drivers. Use the GeoNB Map Viewer Lite for best results.
❌ WebGL not supported — Your browser or GPU cannot run WebGL. Use the GeoNB Map Viewer Lite.
Tips:
Update your browser (Chrome, Edge, or Firefox recommended)
Ensure hardware acceleration is enabled in browser settings
Install the latest graphics driver from your computer or GPU manufacturer
Alternative Viewer:
If your computer continues to show warnings or poor performance, use the GeoNB Map Viewer Lite, which does not rely on WebGL and runs well on older hardware.
