Overdraw optimization In cases where the GPU is pixel-bound, a common cause is overdraw, where pixels are shaded multiple times in a frame. This increases the likelihood of multiple passes being applied to the same pixel, taxing the GPU even more. In some cases, Solid Angle Culling reduced ARTAS processing time by 60%.

It can be directly in the AS build calls or in some related task like the culling of the objects. Cull instances for TLAS. Instead, cull instances depending on the situation. For example, consider culling based on an expanded camera frustum. Use face culling only when required for correctness. Avoid deep recursion.

NVIDIA DLSS Plugin for UE4 DLSS is a deep learning super resolution network that boosts frame rates by rendering fewer pixels and then using AI to construct sharp, higher resolution images. The NVIDIA RTX UE4 4.25 branches have also received updates. Updates to NVIDIA RTX UE 4.25 The new NVIDIA UE 4.25 and UE4.26.1,

For example, a shader can use warp shuffle instructions to exchange data between threads in a warp without going through shared memory, which is especially valuable in pixel shaders where there is no shared memory. For example, warp shuffle can be used to optimize memory access in algorithms like light culling. x, u1 mov r3.yz,

Rendering: Portal occlusion culling. Portal occlusion culling. Up till now a significant missing feature in the renderer has been the ability to cull (prevent rendering) objects that are within the camera view, but occluded by another object (for instance a wall). Core: Promote object validity checks to release builds.
