      Just do the 'Graphics Feature Status', 'Driver Bug Workarounds' and 'Problems Detected' sections if that makes it easier. Below you'll see my output. Its fairly standard for a Windows machine.

      Use four spaces at the beginning of each line to indicate a block of pre-formatted text, such as code samples.

      Example:

      Graphics Feature Status
      Canvas: Hardware accelerated
      Flash: Hardware accelerated
      Flash Stage3D: Hardware accelerated
      Flash Stage3D Baseline profile: Hardware accelerated
      Compositing: Hardware accelerated
      Multiple Raster Threads: Enabled
      Rasterization: Software only, hardware acceleration unavailable
      Threaded Rasterization: Enabled
      Video Decode: Hardware accelerated
      Video Encode: Hardware accelerated
      WebGL: Hardware accelerated
      
      Driver Bug Workarounds
      clear_uniforms_before_first_program_use
      exit_on_context_lost
      scalarize_vec_and_mat_constructor_args
      texsubimage2d_faster_than_teximage2d
      use_current_program_after_successful_link
      Problems Detected
      GPU rasterization is blacklisted on non-Android: 362779
      
      Disabled Features: gpu_rasterization
      Always call glUseProgram after a successful link to avoid a driver bug: 349137
      Applied Workarounds: use_current_program_after_successful_link
      Some drivers are unable to reset the D3D device in the GPU process sandbox
      Applied Workarounds: exit_on_context_lost
      TexSubImage2D() is faster for full uploads on ANGLE
      Applied Workarounds: texsubimage2d_faster_than_teximage2d
      Clear uniforms before first program use on all platforms: 124764, 349137
      Applied Workarounds: clear_uniforms_before_first_program_use
      Always rewrite vec/mat constructors to be consistent: 398694
      Applied Workarounds: scalarize_vec_and_mat_constructor_args

        lando242 May I ask a question. I have used Opera for many years, but am not a computer expert by any means. I am also experiencing the problems mentioned here. I am not able to find the Opera profile folder to see if I have the files with 'sessions' there! Can you help me navigate there please?

          Opera Menu > About Opera. It says the location of the profile folder near the bottom of the page.

              Ditto, same problem, except my lags are about 3-5 seconds long every 20-30 seconds. Opera is now impossible to use.

                  Did you try the deleting of the sessions files?

                      Read the first reply to this thread, that should cover it.

                        When I go to the AppData\Roaming\Opera Software\Opera Stable there are no files in that folder with "session" in them
