I've tried multiboxing two clients at the same time, and my PC freezes to the point where I have to manually restart it. Sometimes it happens after a couple of minutes, sometimes after 20 minutes. It doesn't matter what I'm doing ingame, recently it crashed after just five minutes of idling in town with both characters.

I'm using the lowest possible settings, NVIDIA DLSS is off, windowed mode is enabled, and the framerate is capped at 60 for both clients. I also added D2R.exe and set the "Background Application Max Frame Rate" to 30.

I've tried everything, but nothing works. I don't think it's a hardware issue, because my specs are pretty high:
Windows 11
13th Gen Intel(R) Core(TM) i7-13700KF (24 CPUs), 3.4GHz
32GB RAM
NVIDIA GeForce RTX 4090
2TB SSD

Let me know if someone has a solution for this, thanks!

Also this is how my Task Manager looks after crashing

Windows 10 or 11?

Apparently windows 11 recent update has had some issues relating to d2r.

I can’t say as only my laptop and ally is windows 11 and I only run single instances on them.

# Method 1
Download Process Lasso.
Run D2R.
Find D2R.exe in the processes, right-click:
CPU Priority -> Always -> High
CPU Affinity -> Always -> Uncheck CPU 0
Power Configuration -> High Performance


# Method 2
Open the registry path Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\D2R.exe\PerfOptions. If the path does not exist, create a new item by yourself. For example, in this case, you need to create D2R.exe\PerfOptions.
Then create a new DWORD (32) named CpuPriorityClass under PerfOptions.
Double click to modify it to 3.

This ^^

Wrong forum dude this is d2 not d2r

aye bro, goto blizzard settings

APP - Scroll all the way down and disable hardware acceleration. Thank me later

Get Windows 11 23H2 version instead of what ever newer version you have. Microsoft have fuked up online gaming somehow and newest version on Windows causes freezez and lags on D2R, like on other games also. You have to google that older version of windows by yourself because what ever bitch reason Microsoft doesn’t support ”downgrade” to theyr product. This maybe sounds stupid but it’s fact what helped me also.
