Hi there, I’m trying to load a glb with a texture which is 8k / 80M, It takes about 3s to load in 4.2.0 while about 15s in 5.0.0(alpha63).

The performance record shows that the time is mainly cost by `getError`, but even if I rewrite the `_compileRawShader` function to skip the `getError`, the load time didn’t reduce(2nd picture).

Actually I’m not sure if it is the question with BJS as I found the similar problem in 3js v88 / v134.

UPDATE:  
After test, the width / height of the texture effects more on the load time than size.

This is about the color space of the texture and an internal bug in Chrome open from quite some times now ☹

Hi @tanpopo ! We’ve recently merged an issue related to slow loading times on 5.0.0 [Added option to force sRGB Buffer support state by RaananW · Pull Request #11758 · BabylonJS/Babylon.js (github.com)](https://github.com/BabylonJS/Babylon.js/pull/11758) can you update your project to check if it helps in your case too? 😄

There is no npm version with the fix yet, I am updating the preview release as we speak.

@carolhmj @RaananW, I didn’t clone the preview release but turn off `supportSRGBBuffers` and the problem is solved, Thank you!
