I think my desktop is underperforming, it can barely run fortnite, having roughly 26fps. Csgo at 40fps, and Dota 2 at 40fps. The settings that I set when playing are 1080p with medium graphics. When I check my radeon drivers, it says vega 8 apu is being used. Is my rx550 used? I've also updated the drivers for the gpu.
My specs are
A320 Asus Prime
Ryzen 3 3200g
1x8 Ram 2666mhz
I'm new to setting up computers,
so I guess I'm pretty much blank about this problem.
You've likely plugged into the wrong HDMI port on the back of your PC. Your Radeon RX550 has its own HDMI input, separate from motherboard's built in HDMI input. head around to the back of your PC and see if there's another place to plug your video cable into.
They won't work together it's one or the other.
Open up Device manager.
Under display adapters find your vega graphics.
Right click on it and select disable.
This will force your computer to use the video card.
Was your rx550 showing in device manager?
Is it showing in the radeon software under settings>System>hardware?
Is the monitor plugged into the graphics card or the motherboard?
