I have numerous ssd’s so can sacrifice 500gb hi @AtAshTag @Hardcawcanary , Recently with 34.00 Feature Examples [TMNT City Sample Error](https://forums.unrealengine.com/t/tmnt-city-sample-broken/2364762) Adding a 64 GB page file for Virtual Memory fixed the problem. see this post You may need to add a 64GB pagefile.sys, which I documented in [Install a bigger pagefile.sys](https://forums.unrealengine.com/t/cant-create-c-project-or-use-c/238169/2) You can use any SSD drive to full size and its better if the pagefile is on a dedicated drive. My laptop needs 32GB as it’s a home laptop with 8GB, so my 32GB pagefile just about does the job and its a lot cheaper than a top spec laptop, being an indie. UEFN and Fortnite used to run at 18GB in 30.00 UE5.5 and now we have UE5.6, generally its over 20GB ![IK RetargeterPagingFileSize](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/9/1/39106675b72baa3ddafce5269cb0b317d53734f3.png) More recently a bigger pagefile fixed this problem [IK Retargeter Causing UEFN To Crash - General / Issues and Bug Reporting - Epic Developer Community Forums](https://forums.unrealengine.com/t/ik-retargeter-causing-uefn-to-crash/2364753/8) Whenever MS Edge, based on Google Chrome, is running for the editing of posts, then the memory, basically takes 10.8 GB for 8 windows Epic Community posts to take this up. --- _[View the full topic](https://forums.unrealengine.com/t/uefn-memory-leak/2356972)._
