What is OVR_multiview2?
The OVR_multiview2 extension is part of the WebGL API and adds support for rendering into multiple views simultaneously, especially useful for VR/WebXR. Provides framebufferTextureMultiviewOVR() method and constants like MAX_VIEWS_OVR. Requires WebGL2 and GLSL 3.00, not available on all platforms (Windows+ANGLE and Android supported). Available in WebGL2 only.

Checking Extension Support
This extension is part of the WebGL2 specification.
Browser support varies based on:
- Graphics card model and capabilities
- GPU driver version
- Browser version and vendor
- Operating system
Usage in Web Scraping & Anti-Bot Bypass
Modern anti-bot systems verify WebGL extensions to detect automated browsers. Mismatches between GPU hardware and available extensions are strong bot signals.
What Anti-Bot Systems Check:
- Extension availability: Does the reported GPU support these extensions?
- Extension combinations: Are the extensions typical for this GPU model?
- Consistency checks: Do reported extensions match other GPU signals?
- Missing extensions: Are expected extensions for this GPU absent?
Scrapfly's Anti-Scraping Protection (ASP)
Scrapfly automatically manages WebGL fingerprint consistency, ensuring all extensions
match the emulated GPU profile. This prevents detection by anti-bot systems that verify WebGL data.
