Greetings!

Two weeks ago I plug in second R9 270X in my PC and have some problem in GTA V that I can't undestand. I call this "asynchron load".

My system:

  • AMD Graphics Card
  • Desktop or Laptop System
    • Desktop
  • Operating System
    • Windows 10 Pro 64bit
  • Driver version installed
    • Radeon Software Adrenalin 17.12.1
  • Display Devices
    • Asus PA238Q 1920*1080 @60Hz via DVI cable.
  • Motherboard + Bios Revision
    • MSI Z77A-GD55, Bios version: 1.11
  • CPU/APU
    • Intel Core i5-3570K
  • Power Supply Unit  Make, Model & Wattage
    • Aerocool Strike-X 1100W 80Plus Gold
  • RAM
    • 16GB DDRIII (4*4GB Samsung 1600MHz CL11)

 

In GTA V I use high-ultra setting in most options considering 2GB Vram. Suddenly, i have problem with different settings, not important how much Vram it required (below 4096MB or more). Game can work without any trouble for 6+ hours with average framerate 60 (Vsync in GTA V settings and FPS limit in RTSS) even with ultra textures, but not always. I can't explain whats happening, in some moment (after loading from bunker to surface or just while I driving the car) I have "over9000" stutters with insane Framerate and Frametime graphs. It can be GPU's usage like 30%\99% or 99%\30%, or 99%\99%. Sometimes it goes away in a few minutes, sometimes alt+enter helps me (strange when after alt+enter in windowed mode I see 60fps and normal synchronous GPU's usage), in most cases I just reload the game. Problem is seen on Windows 7 Ultimate 64bit with 17.12.2, Windows 10 Pro 64bit (clear installation after formatting HDD) with 17.7, 17.12.1, 17.12.2 and 17.4.4 AMD drivers.

 

I have this not only in OC CPU@4.2GHz and RAM@2200MHz but with stock Bios settings too.

I prepared six screenshots with MSI AB Overlay, 1-3 with normal gameplay and 4-6 just after... lag\bug?

 

What it can be? Problem with PCIE lines in MB? PSU voltage drop maybe? Software problem? With single R9 270X this doesn't happen. First R9 270X works fine since 2013, second R9 270X was purchased in summer 2014 and works fine in CrossfireX until summer 2015 then second GPU was put in other PC. I dont remember something like this after GTA V release in 2015. Since summer 2015 until december 2017 one contact lag in MB socket was broken, now it was replaced and both PCIEx16 slots works again.
