Go to the system blade and then memory. Press Y on either the HDD or a MU and then press X, X, Left Bumper, Right Bumper, X, X. Once you do this a blade will pop up saying: This will perform maintenance on your Xbox 360 storage devices. Do you want to continue? Select "Yes".
I have also played a backup on my buddies Benq 12X 1.41 Flashed drive. It was an original copied retail disc using XBox Backup Creator and was burned at 2.4x on a Verbatim Singapore with Image Burn 2.4.1. I have seen the render issues on his machine and also the texture pop-ups. When playing the "Pressed Retail Disc" this is not the case only with the Verbatim copy. We have also tried TDK discs and the same result is found. On a Samsung drive the copied Verbatim burned games do not have pop-ups and play just fine.
Just some info to think about...
P.S. Things do seem better with 12X flash rather than an 8X flash of the Benq.
