More recently within a Fortnite Texture we needed to set a 200GB page file on a spare NVRAM/SSD drive using Directx12

Here is link to [Installing a pagefile.sys](https://forums.unrealengine.com/t/cant-create-c-project-or-use-c/238169/2)

The most important action is to **untick**  
**Automatically Mananage paging for all drives**

All GPU require Texture/Meshes to be of power of 2 to work effectively see post  
[Power Of 2 Does not work](https://forums.unrealengine.com/t/power-of-2-does-not-work/2024339)

UE5 does not have the UE Fortnite “Conform Textures” function, which fixes texture errors.

Having a RTX 5090 with 32GB VRAM does not solve this any more than using a RTX 2090 because all this does is add Nvidia CUDA cores.

Lumen and Nanite do not use the extra CUDA cores

Here is link to the official post on Direct X 12 settings
