Thought id ask the community, I have a Sapphire RX 6800 reference card with syncretic patch, single 3.46CPU, 1440p monitor. when running W10 game fps is being limited on some occasions, windows power management has a big impact on the card, for example power saving will limit fps to around 90, switch to balanced and fps will shoot up to 180fps,... 100% load on GPU. Then next time switch on the mac its down to 90 again, you can see the load on the GPU is 50%, CPU is at 40%? The GPU will not consistently run at 100%, its like its running in power saving even with balanced or high performance is chosen. Any ideas? I have an RX 5700 reference that runs just fine.
 
I don't know what exactly the problem is, but did you go to the Radeon software, enable Powertune, and allow the card to use max power?

Some card will be defaulted to use a very low (e.g. 50%) power setting in the Radeon Software.
