Hi everyone.
I would like to start to make my first game.
My question is does UE5 supports DX version of explicit multi-gpu?
Or any software based multi gpu computing?
Hey there @KiKiHUN1! Welcome back to the community! So Unreal has support for NVLink and SLI, but unfortunately not for rendering tasks outside of the game, so no easy way to render farm.
I meant the DirectX verison of “sli”.
Like ashes of singularity has.
Ahhh that’s DX12 mGPU I believe. I had heard (but not experienced) that in 5.1 the experimental support had been added/updated but there’s no listed documentation I could find for it as of now. If you give it a shot, let me know! I’m curious about it as well!
- Added support for multi-GPU rendering (mGPU). SLI is required. To enable it, pass
-MaxGPUCount=2
on the Unreal Editor command line and setr.PathTracing.MultiGPU=1
, which can be toggled at runtime. (r.AllowMultiGPUInEditor=1
is no longer required in.ini
files to enable mGPU in the editor.)
