# ES1 Status
|
||
|
|
|
||
|
|
ES1 is implemented entirely in the front-end using features from GLES3.0. Therefore, every backend
|
||
|
|
with GLES3 support (i.e. everything other than D3D9) supports GLES1 as well.
|
||
|
|
|
||
|
|
ANGLE passes GLES1's `MustPass`, however there are known missing features.

### Notes [1]
|
||
|
|
* Logic op is implemented through the `ANGLE_logic_op` or `EXT_framebuffer_fetch` extensions.
|
||
|
|
* Currently, these are supported on the Vulkan and GL backends only.
