Re: Low fps after new gpu

Sounds like the Power Limit is at default > AMD graphics performance

Re: Low fps after new gpu

Kingfish has you on the right track I think! You sound like somebody who might need a little help on what and where this power limit thing is. Open Radeon Settings Click on the Gaming Tab Click Global Settings Click Global Wattman, which is directly to the right of Global Graphics, it's the center tab currently. Then down below the fan settings slide the slider for the for power limit to the right to it's maximum setting this may be +20 or +50 depending on make and model of the card. If this doesn't fix things just reply back with more system details and hopefully someone can get you going from there. Good luck and happy gaming!

Re: Low fps after new gpu

More power is always going to add more heat. The question is how much. Typically those sliders in wattman not like the ones in afftermarket tweakers are within the normal operating range of the card and shouldn't add too much heat. You can always use a custom fan profile to turn on the fans earlier and run them faster if needed too.  I think in your case I would set it at 50 and see what happens you can always go to 75 and try again from there. If the 50 works you can also play with dialing it back from there until you find the sweet spot. I hope this fixes things. It did for me! Always tough to know if someone else really has the same issue. Let us know what ends up working or not working.

Best of luck & happy gaming!

Re: Low fps after new gpu

No sir....the Power Limit is there to disable the throttling that is set at default (0). Set it at the maximum + value (if yours is 75, then set it at 75...cards are different as to what the default is set at...depending on the manufacturer. Do not worry about the heat right now. Post a screenshot of your settings.
