Graphics card upgrade lowered fps ingames.

[Andrewofpisg]

I got a new gfx card a r9 390x xfx 8gb and i also have a fx 6350. I used to have a gtx 660 so I was expecting an increase in speed. I have experienced fps drops in many games and i was wondering is due to my 550w psu or did i not uninstall the nvidia drivers correctly

What psu do you have? 550watts is pushing it a bit for a 390x especially if its a low quality psu. However I doubt this would cause performance issues it would likely just crash or blue screen if there was a power related issue. I would guess their is some issues with your drivers.

Use DDU (Display Driver Uninstaller) to completely remove the old Nvidia drivers.
Make sure you are using the latest AMD drivers from the website and not the drivers included with the card on the disc.

A 550w PSU is a little on the low side for a 390x but as long as it's a good quality unit it will have no issues powering the card.

Hi, also you have to consider the game you play.

Games that are CPU intensive will perform worse on a better GPU due to bottleneck.
Is your CPU overclocked ?

No they wont they will perform the same or better. If the 6350 was bottlenecking a 660 and you put in a 380 it would not perform worse or at least it shouldn't, it should perform the same or better.

Your power supply is lower then the 700w recommended for the GPU that will be an issue. If it were a driver issue you'd have more serious issues not just a lower FPS, so I don't think that is the problem. If you want to be sure boot up in safe mode and go into device manager and see what drivers your seeing for your VGA card. SO you need a better power supply then see if you have the same issue.
