I updated my 580RX 8GB from the 19.9.2 to 19.12.2 this morning.
Previously I had been playing Destiny 2 with an average of 200fps running at the standard 1080p with the settings on High.
After updating my drivers the game dropped to 70-80fps during loading screens (previously at 400fps) and during game play would drop down to 7-10fps in active combat at around 30fps when in a area with little to no action taking place.
I attempted to roll back the drivers to the previous state of 19.9.2 using Device Manager, and restarted the machine.
The fps drop was still constant.
Prior to this update, I had the most recent Windows updates installed, and everything worked fine.
Windows 10 Home 64 on 500GB Samsung SSD 840
Intel i5 9400
16GB DDR4 3200
Gigabite Radeon 580 RX 8GB
Games are installed on a Seagate Bara 2TB 7200
Gigabite MOBO Z370 Gaming 5
Home internet is 200mb down and 10mb up.
Has anyone else experienced this?
Does anyone have any suggestions on how to fix this?
Exactly same thing happened to me too, Apex legends is so unplayable right now and I am suspecting this is the problem but I'm not sure since I've loaded fail-safe BIOS settings after the update for completely another reason that şs not related to this matter.
same problem in apex legends. unplayable game with new soft and drivers. i have now older soft and drivers 19.12.1 an everything is fine for me... i think .... graphic card 5700xt !
Same problem here.. in black desert it seems to be not using the discrete GPU after updating to adrenalin 2020 19.12.2-19.12.3
Weird stuff is that when I connect my external monitor and re launch the game the fps is back to normal.
Same here, I almost got the same comp as you but I have 8gb ram instead. I tried using DDU and reinstalling the driver from 0, but it seems like everytime I restart my computer my graphics are reduced again while using 100% of my GPU.
