The Last of Us Part 1 PC Memory Leaking Fix

The Last of Us Part 1 PC memory leak is just one of many issues currently plaguing the experience of playing TLOU on the PC. After almost ten years, the legendary post-apocalyptic adventure is finally available on the PC. However, the launch has been disastrous in technical terms. In this guide, we explain how to fix the TLOU P1 PC memory leaking issue.

How to Fix Memory Leak in The Last of Us Part 1 on PC

PC gamers had been waiting for ten years to play The Last of Us. Unfortunately, they will probably need to wait a little bit more in order to play the game without problems. A myriad of technical issues has marked the TLOU P1 PC launch. This includes things like 100% CPU Usage, the “Not Enough RAM” error, stuttering, and more. Another such serious issue is TLOU P1 PC memory leaking. Fortunately, while we are waiting for developers to hotfix this, there is an alternative solution.

Namely, it seems that this issue stems from the fact that the PC port of the game uses a bugged version of Oodle. “The developers/porters used a bugged release of the Oodle decompression library (2.9.6) which has confirmed memory leaking issues,” explains Reddit user S5AurA. Apparently, the solution here is to switch the bugged version of this file and replace it with a working one. The file is called “oo2core_9_win64.dll” and exists in the root directory of your TLOU install folder.

As claimed by S5AurA, the working non-bugged version of this file can be found in games like FIFA 23, Warframe and Destiny 2. Hence, if you have these games installed, you can copy the file from there and replace the one in your TLOU folder. Alternatively, you can download it directly from this link. Hopefully, it will fix your problems!
