Not at all. GL_DOUBLE is just plain not supported on swr. If AVX2 presence/absence causes changes in behaviour, you have some configuration issue on your end (e.g. perhaps you're using llvmpipe with one, and swr with the other). [Note that GL_DOUBLE is an almost completely pointless feature - the "GPU" will still convert your doubles to 32-bit floats. If you want to feed actual fp64 values to your vertices, you need GL_ARB_vertex_attrib_fp64 or whatever.]</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
