: You really could have just removed the "2.0"s yourself; it's OK to edit the Wiki. The original text was apparently written before ES 3.0 came out, so 2.0 was all there was as far as shader-based ES is concerned. [[User:Alfonse|Alfonse]] ([[User talk:Alfonse|talk]]) 20:40, 18 October 2019 (UTC)

OpenGL ES Versions

The note about precision qualifiers being specific to OpenGL ES 2.0 only and has no functional effect does not appear to be true. If you read this OpenGL ES 3.0 Quick Reference on page 5 section 4.5 it shows that they do exist. In practice I have seen the qualifiers function on Android 8 Tablets specifically. Another words, when the precision highp qualifier is present the results are different when the precision highp qualifier is not present.

You really could have just removed the "2.0"s yourself; it's OK to edit the Wiki. The original text was apparently written before ES 3.0 came out, so 2.0 was all there was as far as shader-based ES is concerned. Alfonse (talk) 20:40, 18 October 2019 (UTC)
