I have a relatively simple scene and lighting setup.
However my GPU is taking a massive dip when using Megascans grass, and with that I mean that ShadowDepths is taking up 29.84MS and PrePass DDM is taking up 23,60MS.
But when i get too close to the grass it takes, ShadowDepths can take up a massive 46,24MS!!!
But I have no idea what PrePass DDM is, nor could i find anything about it to help me out.
To give more context;
I have a 8kmx8km landscape scene, with a landscape tesselated material. Tesselation multiplier is set to 1.
The scene has Exp Height fog, Atmos fog and a simple PPV with bloom.
My directional light is dynamic and my skylight too.
My shadow distance of the directional light is set to 600000 units.
Also I have Distance Field Shadows etc. enabled.
Without grass my ShadowDepths is taking up 13,95MS and PrePass DDM only 3,56
Is grass with realtime lighting so heavy, or am i doing something wrong?
Would setting my directional light to stationar solve the problem, or would it really need to be static?
Here are some screenshots of my scene;
