      Motherboard: ASUSTeK COMPUTER INC. Z170-AR

      RAM: 2 8GB 2400MHz

      PSU: Corsair CSM 550W 80+ Gold Certified Semi-Modular ATX Power Supply

      Operating System & Version: Windows 10 home

      GPU Drivers: Crimson 16.7.3

      Chipset Drivers: 10.0.10586.0

      Monitor: ViewSonic VX2475SMHL-4K 24-Inch 4K Ultra HD LED Monitor (3840x2160, 60Hz, 3ms, 120M:1 DCR, HDMI 2.0 (MHL), DisplayPort)

      HDMI cable: AmazonBasics High-Speed HDMI Cable

      Background Applications: Firefox/Steam/Origin

      Description of Problem: After trying to update to 16.7.3 and failing, then getting a hang, and having to hold the power button to shut down tf2 with the same settings I've played at started tearing. BF4 got unplayable on 4k with medium settings, which is what I previously played at.

      Troubleshooting: Re-install 16.7.2, problem remained. Uninstall with ddu, install 16.7.3 then disable power savings. Disable ULPS, reboot. Problem persists.

          I noticed this on my motherboard specs:

           

          2 x PCI Express 3.0/2.0 x16 slots (single at x16 or dual at x8/x8 mode)
          1 x PCI Express 3.0/2.0 x16 slot* (max. at x4 mode, compatible with PCIe x1 and x4 devices)
          * The PCIe x16_3 slot shares bandwidth with SATA6G_56. The PCIe x16_3 is default set at x2 mode.
          Was thinking maybe I have my card installed in the PCIe x16_3 slot defaulted at x2 mode and shaed with SATA6G. Looked in GPUz though and it says x16.

            Besides the ominous DPC stacking causing the audio to stutter and framerate to drop significantly, when screen animations are being done, a noticeable screen tearing is observed.   The game uses Unreal Engine 3
