Short description of error

Sorry if my english it´s not perfect. I´ve just bought my new PC with the specifications that I´ve put before. When I have a scene (LOW POLY) with (114.700 verts 138.000 faces 209.000 trips 2300 objects Memory 90.30M ) The scrolling, and the navigation into the scene is so slowly, with a lot of lag, 1 second aproximately. The scene have no lights, and only simple materials, with a colour. All the drivers of my graphics card are OK and I think that the PC with those specifications and a scene LOW POLY dont have to have these problems. I´ve opened the same scene in a very much worse PC, and the scroll and navigaton is OK. I dont know what to do. Please help

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

  • Install the latest graphics driver from the AMD website. I guess you have an "RX 570", since there is no "570 X" as far as I know.
  • Try using File > Load Factory Settings and then opening the file, to check that there are no specific user preferences causing this.
  • Try using the viewport without Ambient Occlusion (in the 3D viewport Shading panel), or reducing the number Samples since they are quite high in this file.
  • Try disabling Background Images, Texture Solid, and similar settings to figure out if any specific one is causing the issue
  • Try tweaking settings under User Preferences > System (Window Draw Method, Multisample, Region Overlap, ...)
  • Attach the file generated by Help > Save System Info.

It was the ¨texture solid¨ that was active, if I disable that, it works OK. A lot of thanks!!!!
