I cant even open the game now?

a few days ago i was playing “just fine” but i had upgraded my monitors to 4k 165 hz refresh, had some random black flashing. whatever, dropped it down still didnt stop the flashing. thought it was my drivers, everything is up to date. so i thought it had to of been a bug and decided to just give diablo a break. ( mind you EVERY GAME i have been playing just fine at max graphs, no issues 100+ fps easily.) now, i tried to open the game, and it was VERY choppy, even dropped my refresh rate down, and turned the graphics down and tried to optimize them and still no no avail, 20 fps? super choppy, i also then tried to scan and repair and reinstall. nothing worked. what the hell is the issue here? im super confused as to why all these issues started once i changed monitors and added a 3rd.

Game doesn’t play well with multi monitor setups.

That said, there are a few things you can do.

For one thing. Regardless what the refresh rate of the monitor you are playing on. If either of the other monitors are capped to a lower refresh rate, it can bork up things with the game. I run two monitors:

32" curved 1440p freesync at 165hz, and a 24" 1080p g-sync at 144hz. And the smaller monitor is even setup in portrait to the left of the big monitor.

Now.

I run an RTX 3070Ti. I run the game capped to 100FPS, with full Ultra. Details on my full system settings can be found here:

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

This plays the game butter smooth still. It also plays other games equally well. Hell Overwatch 2 is the most taxing game on my setup at the moment, as I run it at a higher FPS than Diablo IV.

But your situation is not a new one. Many have had some issues.

Other simple thing you can try first:

Close out of the game AND the battlenet launcher.

Navigate to Documents\Diablo IV

In here, rename the file LocalPrefs.ini.

Then start up and re-launch the game. This will force a reset of the game defaults and will prompt you through first time setup for Gamma. You changed your graphics card setup, but you may want to review some of the Windows settings and stuff I outlined in my link above.

Good luck.

ill take a gander at that. i appreciate that. i was running x2 1080 24 inch monitors, and swapped to x2 2560-1440 monitors + a smaller 1080-720 monitor. i had no issues when running the dual 1080 set up . ive done the whole restart everything and default settings. its kind of annoying that any one has to go through this lol
