Ultimate Guide: Fix Elden Ring FPS & Stutter Issues with CPU Affinity Settings (Works Online)

The Complete guide in fixing Elden Ring's FPS & stutter issue that involves using CPU Affinity settings that isn't talked about much online. This guide shows you two methods in fixing it, one that works with online multiplayer and one with the traditional way of playing offline only. I also included other fixes that other users reported that fixed their issues which you can try. If you don't want to download any additional software, you can use the offline method with the task manager & setting it manually yourself. This guide is inspired by Phyrok & soulgamer31br.

Online Method

This method works with online mode & you are able to play multiplayer. If this does not work out for you, or are not interested in downloading external programs, check the offline method or the other fixes section.

1. Download Process Lasso[bitsum.com]
   
2. At the Toolbar at the top, Click Options -> Power -> Bitsum Highest Performance -> Install/Initialize
   
3. At the Toolbar at the top again, Click Options -> Power -> Start Process Lasso with Power Profile -> Bitsum Highest Performance
   
4. Options -> CPU -> CPU Affinities -> Process Match: start_protected_game.exe -> CPU Affinity, Select, check ALL except CPU 0. Do the same for EasyAntiCheat_EOS.exe
   
5. Restart Elden Ring

Offline Method

First download the Anti-Cheat Toggler[www.nexusmods.com] & disable EAC. Next, there's 3 ways you can do it

1. You can go to task manager, right click elden ring, go to details, right click again, and click CPU Affinity, uncheck CPU 0. (But you have to do this everytime you open up the game)
   
2. Is using this mod[www.nexusmods.com] with mod engine 2. (Set modengine2_luauncher.exe go Properties - Compatibility - Run the program as an administrator. Make sure you're doing this on the actual exe and not a shortcut) for it to work.
   
3. This is what I use, I download Process Lasso[bitsum.com] & set it wherein everytime I open elden ring, it automatically changes the CPU affinity for me. Options -> CPU -> CPU Affinities -> Process Match: eldenring.exe -> CPU Affinity, Select, check ALL except CPU 0. (Do note if you are using mods together with this method, click advanced & set a 30 second delay to not crash)

Just restart after doing it and it should fix the FPS issues.

Mods to use with Offline Mode

On an unrelated note, since you already are forced to play in offline using the main method, here's some mod recommendations that doesn't change game mechanics but gives QOL features.

1. Transmogrify [www.nexusmods.com](Change your appearance to any armor while keeping the stats and bonuses from the armor you actually have equipped)
   
2. Camera Offset[www.nexusmods.com] with Lock Player Rotation[www.nexusmods.com] (Make's the camera while in combat way less clunky for me. Be sure to go to the config file for camera offset & change 'auto-toggle' to 'no' to make it compatible with Lock player rotation.
   
3. Pause the Game[www.nexusmods.com]
   
4. Skip the Intro[www.nexusmods.com]
   
5. Temporal Super Sampling[www.nexusmods.com] (Adds integration for NVIDIA DLSS/DLAA, AMD FSR and Intel XeSS. Give's me an FPS boost as well for not much quality loss)
   

Additionally, you can buy Lossless Scaling in Steam to have the ability to use Frame Generation.

Other fixes

Disabling Microsoft Device Association Root Enumerator

Credits to Watermelon for finding this fix

1. Open up Device Manager
   
2. Under "Software Devices", right click Microsoft Device Association Root Enumerator & Disable Device

What it is: Legacy support for old peripherals such as connecting to old printers, MIDI Devices (used for music creation), Serial port (for hardware repair), CDs & Usb Floppy drives. You can always re-enable this if you ever need to use it.

Setting Custom Frame limit

Other users reported that setting a custom frame limit of 59.930 fixed their stuttering issues. Using native frame limiters to limit it to 60 or 59 does not seem to work.

• Download RTSS[www.guru3d.com]
  
• In RTSS, on the lower right Click Add, locate your Elden Ring.exe which should be commonly in your SteamLibrary\steamapps\common\ELDEN RING\Game.
  
• Click eldenring.exe & on the right side, Set Framerate Limit 59.930

I did the Process Lasso method, and the difference was insane. My game is normally ok with 50-60 fps at most times but at times it would drop to 20-30 fps at certain places like after first grace in Leyndell Capital, now i dont even drop below 60 fps there. I advice you to be careful with Process Lasso though, dont try go extra with changing stuff you dont know about. Awesome guide! :)

Will steam achivements will work when diable anticheat ?
Thanks.

[Ctreix]

Process Lasso made the game crash for me, idk what to do to fix this

[sanbarbing]

I am not sure why I can't change the affinities, already turnoff the UAC and set the file permission to everyone. Already try online and offline, notthing happen to affinities.

[Pave Papi]

Online method no longer seems to work. Elden ring will close on startup if any of the affinities or priorities are changed on eldenring.exe (which is caused by chaning the priorities or affinities on "start_protected_game" during EAC startup afaik)

[Erbista]

hmmm this is not working for me even though i traced every step right :( even tried delay... my 1st core on the graph still runts at 100 %, any help? :/

[Romarus]

did not help me =(

[Buura]

Process Lasso is doing nothing to my stuttering issue :(

[Punch Rockgroin]

Yo this is insane. Fighting consort radahn, my fps went from 40s to dips into the 20s to solidly above 50 the whole time after doing this. Ancient i5 4690 with Rx 6600xt
