gpu upgrade performing worse

[max2195]

i just upgraded my gpu from a gtx 1650 to a radeon rx 6600

on paper this is meant to be a much better gpu but it is hitching a lot and getting high fps drops and lower fps

my pc specs
i7-9700k

64gb 3600mhz corsair vengeance ram

z490 motherboard

corsair 650w psu 

 

i have been monitoring the temps and they havent been getting very high so it cant be that

I would try DDU: https://www.guru3d.com/files-details/display-driver-uninstaller-download.html

 

This will nuke the old nvidia drivers (an I would nuke the AMD driver as well) and start over with fresh drivers from AMD.com
