Wattman crashes to much and resets to default. It has a lot of awesome features. What worries me about afterburner is seeing the clock jump up way beyond boost in GPU-z when a application crashes coupled with an OC. I don't think that happens with Wattman. idk if that's a valid concern about AB, it is in Beta a stage. MorePowerTools is definitely ftw. I wish they had a turn Wattman on and off toggle button at least until they fix it. So I could change settings like anti lag\RIS then turn it off.
If you are using AB and something crashes, it may reset your OC settings, you have to chose new settings for your clock\power\core etc, apply, then you can apply your old settings. Some kind of bug. Easily confirmed with GPU-Z.
