Why Does Firefox Handle Large 3-4GB Models Better Than Chromium on Windows?

I've observed that when loading very large models (around 3-4GB) on Windows 10/11, Firefox manages them much better than Chromium-based browsers.
Using Firefox, I was able to load three models of 3-4GB of position/index data without issues. In contrast, Chromium-based browsers could load only one model (two with ANGLE set to OpenGL); starting another resulted in frequent 'context lost' errors.
Notably, on Linux, the Chromium-based browser handled four large models without causing this problem.
On a small laptop, Chrome/Edge couldn’t load the model at all, while Firefox managed to load two successfully.
Although loading such large models may be unusual, it seems like a potential bug in Chromium. Has anyone else experienced similar issues?

WebGL Memory Management Differences Between Browsers
Your observation about Firefox handling large WebGL models better than Chromium-based browsers on Windows is interesting and likely related to differences in GPU memory management between browsers.
Possible Explanations
-
Different WebGL Implementations: Firefox and Chromium have different WebGL implementations. Firefox might have more efficient memory management for large models on Windows.
-
ANGLE Differences: Chromium uses ANGLE (Almost Native Graphics Layer Engine) by default on Windows, which translates WebGL calls to DirectX. Your observation that setting ANGLE to OpenGL improved performance supports this theory.
-
Memory Limits: Chromium-based browsers on Windows might have stricter GPU memory limits or different memory allocation strategies than Firefox.
-
Platform-Specific Behavior: The fact that Chromium performs better on Linux suggests this is a Windows-specific issue, possibly related to how Chromium interacts with Windows graphics drivers.
Potential Workarounds
If you need to continue using Chromium-based browsers with these large models:
- Try enabling hardware acceleration flags in chrome://flags
- Continue using the ANGLE OpenGL backend that gave you better results
- Consider splitting your models into smaller chunks if possible
- Implement progressive loading techniques
This does sound like it could be a limitation or bug in Chromium's WebGL implementation on Windows. You might want to report this to the Chromium bug tracker with your specific test case.
