What is this option for.. when i turn it off my gpu clock will bounce all over the place. As soon as i turn it on my clocks are rock solid, should it not be the other way around
its AMDs power saving features. Clocks are supposed to bounce around. Theoetically you should see any difference in performance between it and full clocks, but just in case you do there is an option the turn in off in crimson. It only for on 390/fury.
I hear what your saying but if i turn that option on then my clocks are solid 1050 but if i turn the option off then it jumps between 980 to 1023. its working the wrong way for me
Power Efficiency on my R9 380 doesn't really reduce fps i think, but what it does introduce is Stutter cause of frame timing i guess. It's very obvious, feels like i have 40-50fps instead of 60.
I don't think so. If I'm no mistaken this option is to turn OFF/disable power saving. So if you turn it ON you turn OFF/disable power saving features.
Setting it to off most likely restores the pre-crimson power saving behavior. Instead of offering this stupid option they should rather have rolled back to pre-crimson behavior for all cards by default. When it's set to off, there's still downclocking going on as you'd expect it, and with it on, there's hardly less power consumed on the cost of nasty stuttering. Really, really stupid and confusing. Not just for the users, but also for AMD itself, since they look bad when there are frametimes monitored by reviewing sites.
