Full breakdown of a system that plays Diablo IV without problems:


I know many of you are having some issues. So I wanted to do a full breakdown of my system, every little setting that might contribute, from Windows, to drivers, to in-game settings, and what it’s running on. So here we go:

The system

I built this computer earlier this year back in May. This is a composition of new and used parts.

New Parts:

  • Intel 12900K. (i9) 5.2GHz, 125W
  • MSI Pro Z790-P WiFi (PCIe 5 support, DDR5 support, 4x M.2 slots)
  • MSI MAG CoreLiquid 360R V2 AIO
  • Kingston Fury Renegade 1TB NVME with up to 7300MB Read/7000MB Write
  • Kingston Fury Beast 32GB Kit DDR5 5600
  • BitFenix Spectre Pro RGB 140mm Fans x2
  • MSI Optix 32" Curved Freesync 165Hz

Open boxed or Used Parts:

  • Corsair AX1200i (was new in-warranty replacement)
  • MSI Gaming X Trio 3070Ti (Used from eBay, but complete with box)
  • CoolerMaster HAF 932 Advanced Full ATX Tower (Used with previous gaming build)
  • Samsung 2TB SATA based SSD (Used from previous build)
  • Other drives, including Blu-Ray, HDDs for large storage, and multi-ext interface drive (all used from previous build)
  • 280mm Fan (came with case)
  • Acer Predator 24" Gsync HD monitor (used)
  • Logitech Performance MX with Darkfield (ancient rechargeable)
  • Corsair Basilisk V2 (used)
  • Generic Keyboard (used till updated later - was on a Razor BlackWidow Chroma, but it died)
  • Altec Lansing 5.1 Analog multi-cable sound system (used)
  • APC UPS 1500 Pro Backups with extended battery pack (Used and under full game load with both monitors it maintains about a 90 minute run time)

Internet available:

  • Primary internet is Starlink. It is capable of speeds between 75MB to over 300MB. Works fine, except for when trees have leaves and/or really heavy weather. Then it can cause spikes in latency.
  • Secondary internet is Brightspeed DSL. It has a speed of 8MB. I pretty much just use it to game on for just this machine. It doesn’t connect to anything but the computer. And it will maintain a pretty solid latency between 60-90 in most games, including D4.

Operating system is Windows 11 Pro with the latest updates. The following are the Windows settings I run that have a direct bearing on game performance:

Base system settings:

  • Swap file is disabled.
  • I log in with a Local Admin account.
  • Sleep is prevented (disabled).
  • Fast Start is disabled.
  • Windows update is set to automatic and to get the latest as soon as possible.
  • Optional updates are checked manually every so often and done.
  • Focus is enabled and system is set to do not disturb.

Display settings for Windows:

  • Running a dual monitor setup.
  • 32" MSI Curved Freesync is my primary monitor. Set to 1440p Native and 165Hz (164.55) using a display port cable.
  • 24" Acer Predator G-Sync is my second monitor. Set to 1080x1920 (portrait) and 144Hz (143.98) to the left of the MSI monitor also using a display port cable.
  • Using a background that is spanned across both monitors.
  • HDR is enabled on the 32" and not available on the 24".

Under Graphics:

  • In the list of Apps, for Diablo IV Retail, it is set to High Performance Nvidia Geforce RTX 3070 Ti.
  • Hardware-accelerated GPU Scheduling is On.
  • Flip Presentation model is enabled (for HDR support).
  • Auto HDR is enabled.

Video Driver version and settings:

Currently (at the time of this post) using Nvidia Driver version 535.98 that was released on May 30th. I had installed it on June 1st. The same day I installed the 3070 Ti. The driver settings below may not be the same on all versions of the driver.

The result of all this?

The system plays this game near flawlessly. It will maintain the Ultra quality and stays at 100 FPS 99.9% of the time.

Its rare to see it dip down, and the most likely times it might are when teleporting back to a town, or clicking on a merchant once in a while. Even then, the disruption is a second at most then right back to 100.

Load times are quick, very little delays between teleports and practically no notice of zone changes.

It might be a tad more noticeable when around multiple players in a town, but even then its still smooth.

No freezing, no stutter, no latency (unless I play on Starlink) and can play for hours.

Temps never seem rise above 70C on any portion of the system. The GPU will average low to mid 60s across the GPU, Mem and hotspots, even at a vendor for an extended period.

I even played earlier tonight for an hour or so, and even took the risk on my Starlink connection. Had two instances where it had latency thanks to the rain storm we are having, but it was fine otherwise. Never lost connection, or crashed or froze.


I’m providing as much detail as I can to hopefully help some of you.

Any questions or something you want clarified, ask!

Good night and good luck. Those having issues, hang in there, I’m sure there is a way to resolve it, one way or another. :smiley:
