    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

       

      before:

      Powercolor HD7870

       

      before:

      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.

       

      Greetings,

      Lugge

       

      THANKS FOR ANY HELP! :-)
