Edit: Do not use with v1.09 firmware, it is not compatible
I have been looking at the gtab update and it appears that most of the tegra drivers have not been updated with v1.08. I have remade the pack for that firmware. The quadrant score remains the same at 2400+ but i have noticed a big improvement in the overall smoothness of the device. Games like angry birds and 8ball seem to play smoother. Also, it might be me but iplayer also looks better. Please try it out and report any feedback.
I have packaged it as a update.zip so it can easily be installed on any os. Clockwork Mod is not required.
1 - Download Performance_packv1.08.rar parts 1 and 2 and unzip them (you only need to open one of them), Copy peformancev1.08_update.zip from the performance folder, and place on sdcard of device.
2 - Navigate to settings/software tool, and browse to Performancev1.08_update.zip.
3 - Run the update, the device will reboot and a "out of the box android" will appear, after the device will reboot.
4 - Check the pack has installed by navigating to settings/about Device, under the model there should be "performance pack".
Please make sure you have sufficient power to apply pack, i would recommend 50%
You will not lose any of your apps/data from this process.
Sorry for the 2 .rar parts, its the only way to fit it onto site.
