so, if in vertex shader i do not specify a precision for a vertex shader output varying variable, and in the fragment shader i specify it with lowp or highp, will this cause a mismatch problem (have a risk of low performance) ?I seem to remember an issue of severe performance problems if your vertex shader output precisions mismatch with their corresponding pixel shader input precisions.
