A new version of ATI Tool that has been in development for awhile, is now released. There are many fixes, and they highly recommend you get this version. Here are a few of the new features:
• When multiple ATI cards are installed, you can now select the one to use
• Crash issues when returning from standby/hibernate with Catalyst 4.8+ fixed
• Added Memory Timings options to profile
• Added Gamma options to profile
• Added option to control artifact detection sensitivity
• ATITool will now try to use the D3D device which matches the active card
You can get the new version over at Tech Powerup.
