I’m using a XFX AMD Radeon R9 280X Black Edition with 3072mb VRAM.
I’m also using Win10 with AMD Crimson Edition 16.1.
Also my Scalability Settings are all set to epic.
However, at project startup, UE calculated the texture pool size incorrectly.
LogD3D11RHI: Found D3D11 adapter 0: AMD Radeon R9 200 Series (Feature Level 11_0)

LogRHI: Texture pool is 1361 MB (70% of 1945 MB)
Why is it calculating 70% of 1945mb instead of the full 3072mb? I don’t have any other programs running that would affect my VRAM.
The Texture Pool size is not something that is set automatically based on your VRAM, but instead based off of the Texture Quality scalability settings. It goes from 200MB at the lowest setting to 1000MB at the top setting. At first launch, it is set to 1945MB(I think this gives it a larger cache to make engine startup smoother), but if you look further down in the log it is set to 1000MB.
You can change it manually by using the “r.Streaming.PoolSize #” command. The # will be a MB amount.
You can also add “r.Streaming.UseFixedPoolSize=True” and “r.Streaming.PoolSize=#” to your Project\Config\DefaultEngine.ini file under the RenderSettings section.
I don’t recommend increasing it too far though because there is a good possibility for loss in performance. Texture pool should not take up your entire VRAM
