So i have a Intel i7 8700k @ 3.70GHz , Nvidia GTX 1080 Ti and 32gb of Ram which is way more than enough to run D2R yet i was normally stuck at 30-40 FPS max even though i could run way more graphically intensive games with 200+ FPS... After changing these settings i'm now at 90-100 FPS consistently.

And if you do a quick search on google there's countless Blizzard Forum Threads : https://us.forums.blizzard.com/en/d2r/t/30-40-fps-on-a-3080/14826
of people with even better PCs than me having the same issues, then theres people with totally trash PCs getting even better FPS than us lol....
I tried tons of things to fix this, even wrote BNET support just for them to basically say "Yea we arent aware of such performance issues, therefore they dont exist"

First thing i recommend is disabling all Overlays including Steam, Discord and Nvidia Geforce Capture..

Second and most importantly is to enable "Ultimate Performance" mode for your power options. For some reason this option isnt even available by default on most Motherboards and has to manually be activated through command prompt

Press WINDOWS KEY + X then open Windows PowerShell (Admin)
Type this command : powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61



Third step is to change the Windows Graphics Settings for the D2R applicaton
Go to PC Settings and search for Graphics Settings
In there Browse for the D2R.exe, add it and set it to High Performance as shown below



Finally there is 1 last thing that i noticed can cause serious performance issues and that is having a USB controller plugged in but not using it and instead using Mouse + Keyboard.
I play Fighting games like Tekken 7 so i normally have my Arcade Stick plugged in and set aside but i actually noticed this to be a cause of performance issues not only in D2R but other games like Killing Floor 2 and Smite ... So make sure if youre using a keyboard + mouse and have a USB controller plugged in to unplug it..

I hope this solves your issues. And if it did feel free to donate some Forum golds
