'Req. tex.' column in that table means that texture mapping with this format should work (sample from in a shader), it does *not* mean that rendering to such format should work, for that there is column 'Req. rend.'.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
