ATIccelerator II buns alter ATI graphics cards frequencies live, on-the-fly, under Mac OS X. It's much more sophisticated and convenient to consumption than ATIccelerator I for the following reasons: no potentially dangerous flashing required no cumbersome three-steps outgrowth (ditch, modify, then reflash ROM) no pauperism to reboot for every frequency alter no OS 9 required (that's correct, G5s and other recent OS 9-free Macs are nowadays supported!) What's New: Versopn 1.0.4: Support for the Radeon 9200 Mac Edition. Pressing Option when opening ATIccelerator II ignores frequencies saved in the preferences file (useful in sheath of a too high frequency). Uninstaller (assort of). And a few hemipteran fixes: Set custom frequencies at startup option works again for everyone (hemipteran introduced in an earlier version...). Real and displayed frequencies no longer get out of sync (an alert sheet appears should a frequency alter bomb); line that changing core frequency of some chips, equivalent some Radeon 7000, motionless won't get any force. Frequency changes should no longer bomb with a 10000003 erroneousness logged on the console. Frequency changes failed when the ATIccelerator II preferences pane was selected for the irregular time or more without quitting System Preferences. Erroneous percentage reckoning in some cases. Wrong decimal separator character in some cases.
