Rage3D have released another update to their tweak tool

Here's what their saying

This is a Beta! I've tested the Overclocking on the 7500 and 8500, and it works, but there is a kludge tweak that you Must change to have the OCing work right on the 7500/8500 for now. An update to the OC libraries should remove the need for this kludge in the future. For now, please let us know in the feedback thread your experieces with OCing on the 7500/8500.
