I'm pretty sure I did test this at the time, and it didn't work. But I'll try again to make sure. I don't remember the details precisely, but there general idea is: - part of the scene is rendered - then the z buffer is converted to a linear texture - downscaled with a shader to a new texture - the new texture is then converted back to a htile zbuffer(*) - and some more rendering is done at that lower resolution, in parts not occluded - and then all is blended together for presenting So the problem is that the (*)transition does need to convert the data and not just clear the buffer.</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>
