found out the problem is the memory clock dipping from 1700 to 1100 straight then come back up again sigh but not sure how to fix it..driver or hardware issue? many pp also experience same issue ****
I think need to wait for drivers mature then can buy.
Early adopters will be frustrated
It's been over a yearHow long more? Since 5700/5700xt released until now still not solved.
You can set the Dota2 launch options to "-dx11".
thanks bro.. anyway all i solved it with using vulkan render instead of directx..no more fps drop smooth like **** shiok.. apparently i read that amd sync better with vulkan
