Extension name defined even if not supported or enabled #99

Closed BoyBaykiller closed 1 year ago

BoyBaykiller commented 2 years ago

Using RGA 2.6.2 the name of the following extensions are defined even though the RX 5700 XT I am running this on doesnt support them.

GL_NV_compute_shader_derivatives
GL_NV_shading_rate_image
GL_NV_viewport_array2

Example:

#version 460 core

#ifdef GL_NV_compute_shader_derivatives 
// code in here is supposed to be ignored but it's not
#endif

If I run this code through a OpenGL application it behaves as expected.

I assume this is the case for more extensions than the ones I listed.

I noticed these extensions were added in the recent driver release 22.7.1. As far as this goes this issue can be closed.

I have a question about GL_NV_shading_rate_image though. Why can I use glsl functionality from this extension but can't load the functions introduced by it. Are client side functions like BindShadingRateImageNV not implemented yet?

GL_NV_compute_shader_derivativesshould be supported by the driver soon. There is no plan for supporting GL_NV_shading_rate_image and GL_NV_viewport_array2. These should have been disabled in the driver - will be fixed in a future driver release.
