Valheim FPS Boost Guide
Super FPS optimization guide for Valheim.
A user on Reddit has discovered a few quick fixes that could result in a huge increase in performance.
When running Valheim at all graphics settings at 1440p, you get around 60 FPS (usually lower in densely forested areas). After taking the three steps outlined in the Redditor RustyB3ans' manual, you can see the performance increase to 90 FPS. This is a massive 50 percent gain in performance.
Here is step by step Valheim FPS boost:
Right click on Valheim in your Steam library and go to 'Manage' and then 'Browse local files'.
This should open a window of Valheim's files. Click on the Valheim_Data folder.
Find the file named 'Boot' or 'boot.config' and open it with Notepad.
Add gfx-enable-gfx-jobs = 1 as a separate line at the top.
Add gfx-enable-native-gfx-jobs = 1 just below the first line.
Save and close the file.
Go back to Valheim in your Steam library, right click and choose 'Properties'.
Add -windows-mode exclusive to the launch options area.
Close the window.
Open Task Manager (press Ctrl + Alt + Delete) and find Valheim under the processes tab.
Right click and select "Go to details".
Right click on Valheim.exe, select 'Set Priority' and change it to 'High'.
You will have to repeat this last step with Task Manager every time you start the game.
And that's it! You should now notice a jump in your overall FPS. If you're getting any strange lighting or graphics errors, RustyB3ans suggests you delete the entry gfx-enable-native-gfx-jobs = 1 from the boot.config file.
If the solution works for you, mention it in the comments. Judging by the responses in the Reddit thread, many gamers are getting noticeably better performance.
