RX 480 low fps in all games except Benchmarks

Hello everyone,

as I´m new to this community, let's introduce my system:

Ryzen 7 1700 (OC to 3,8 Ghz)

16 GB GSkill Ripjaws4 2666 MHz

XFX RX 480 8GB Black Edition

Asus Prime B350 Plus

Corsair Force LS 240GB SSD

Seagate 2TB + 500GB HDDs

Enermax Triatlor Eco 550W semimodular

Coolermaster Nepton 240m

Win 10 Pro 1803


Powercolor HD7870


FX 8350 RX460 etc..

So as you can see, my system is optimized for videoediting, and that works fine. But from time to time, I also want to play Farming Simulator 15, Euro Truck Simulator 2 and Spintires.. all not that graphic-intense.. they worked fine with my FX system and later with my Ryzen + HD 7870.. fps never dropped below 30. Btw.. you can see the euphoric me finally upgrading with this Ryzen system some weeks ago: HighEnd Videoschnitt-PC selber bauen | Ryzen 7 | Wasserkühlung | Fractal Design - YouTube

However, about two weeks ago I finally had the money to upgrade to a RX480. 4 times the VRam of the HD7870 and overall better performance.. I hoped to get. But no, I dident. Why.. I still don´t know, I was searching the internet for about 16 hours, having support with the AMD-team, an IT-friend.. Here is what I did:

When upgrading to Ryzen, I did a clean install of win 10 and all the drivers, graphics driver was the latest of AMDs website.

Support suggested to try several other options of drivers and settings

3D-Marks and userbenchmarks results are the same as of other RX480s

Powerlimit is at +50

same problems in other PCIe slot, 3.0x16 works

ingame, clock stays at 1338/2000MHz, temps at 70°C

No other problems as bluescreens at all!

But why do I get only about 30 fps in FS15, 15 in ETS2 and 40 in Spintires, whilst I got 40/45/60 with the HD7870?

To make sure the VRAM is fine, I tried Notruf 112, there about 6 GB were full and no even deeper drops in clocks/fps, but also there much lower fps than the HD7870.

No other Programs were open in the background.

Since I don´t get warranty (its already two years and three weeks old) I really whould be happy if you could help me solving that problem; if you need further information, I`ll provide :-)

And sorry about my bad Englisch, I´m from Bavaria.

Well, I tried 3D Mark time spy once again and found out that I messed up with time spy and time spy extreme... i got about 4300 points in time spy but compared it to <4000 in time spy extreme... so i looked out for a bench sample of another RX480 in time spy, and... it got about 7600 points there, whilst mine only got 4300.. so something definitly is wrong.

My RX480: AMD Radeon RX 480 video card benchmark result - AMD Ryzen 7 1700,ASUSTeK COMPUTER INC. PRIME B350-PL...

another one: AMD Radeon RX 480 video card benchmark result - AMD Ryzen 7 1700,ASUSTeK COMPUTER INC. PRIME X370-PR...

Any ideas yet? :-)
