Some examples include:Ī full EarlyZ pass costs more draw calls and some GPU cost but it avoids pixel processing in the Base Pass and can greatly reduce the cost there.

Some passes can have an effect on the passes following after them. Post processing: Some passes are shared, so toggle show flags to see if the effect is worth the performance. Tiled deferred lighting: Toggle r.TiledDeferredShading to disable GPU lights, or use r.TiledDeferredShading.MinimumCount to define when to use the tiled method or the non-deferred method.Įnvironment reflections: Toggle r.NoTiledReflections to use the non-tiled method which is usually slower unless you have very few probes.Īmbient occlusion: Quality can be adjusted, and you can use multiple passes for efficient large effects. Toggle r.HZBOcclusion to see if you do better without it on.ĭeferred lighting: This scales with the pixels touched, and is more expensive with light functions, IES profiles, shadow receiving, area lights, and complex shading models. Occlusion culling: HZB occlusion has a high constant cost but a smaller per object cost. Shadow projection/filtering: Adjust the shader cost with r.ShadowQuality.Disable shadow casting on most lights. The pixel shader is only used for masked or translucent materials. Shadow map rendering: Actual vertex and pixel shader is defined in the material graph. There is an additional cost for indirect lighting on dynamic objects. Actual vertex and pixel shader is defined in the material graph. This can be customized with r.EarlyZPass and r.EarlyZPassMovable.īase Pass: When using deferred, simple materials can be bandwidth bound.

draw call heavy, complex materials, dense triangle meshes, far view distance):ĮarlyZPass: By default we use a partial z pass. It makes sense to look at the high level cost in each frame and get a feel for what is reasonable (e.g. ProfileGPU shows the light name which makes it easier for the artist to optimize the right light source.
