GL places index clamping prior to adding the index offset and if hw follows this rule, there is nothing sane to be done. VAP_INDEX_OFFSET is completely orthogonal to VAP_VF_MAX_VTX_INDX. The latter contains a minimum allowed buffer-object size divided by a stride, having nothing to do with actual indices. To support index offsets, we would have to check content of every index buffer, which I am not a fan of. Opinions? -Marek
