Hi,

A few days ago i bought a Radeon VII GPU, and i have a few issues with it.. Not the common child diseases you might have heard of.
No, i'm lacking serious low FPS in low-medium games, such as League of legends, GTA V and Assetto Corsa.
I run:
16gb RAM
Win 7
1440p screen
I7 4700k
750Watt PSU
Z87 pro motherboard

In GTA V with ultra settings i get roughly 40 FPS.
In league of legends i get 50 FPS, but it feels like 5-10 FPS, i can barely move around.
And the story continues, i have the latest drivers - the first thing i did, was to download the AMD client and update the drivers. Before installing the card, i reinstalled my Nvidia drivers.
The card performs so badly, i currently took my old GTX 780 back in use..

Could the reason for my ridiculous low FPS by that my CPU is a bottleneck or is the card faulty?

A 4770K (or 4790K) wouldn't be a issue, I think the problem is your PSU, what is the exact model?
Hi Wildcard999,

my PSU should be alright i think, i used to run SLI 780 in the past with this PSU.

the model is: Netzteil Seasonic 850W X-850 Gold (80+) Modular retail (SS-850KM F3)

Ok so the PSU is fine.

You may need to use DDU to uninstall both Nvidia & AMD drivers then reinstall the AMD drivers. You can use the iGPU on the CPU in the meantime.

I haven't used DDU but you may want to uninstall everything offline so Windows doesn't try to update the GPU, then go online and get the newest drivers.
Great, thanks for the tip.. I will try that within a few days :)
