Here are my settings to speed Visual Studio and in particular IntelliSense up for C++ development. They should make working with C++ in large codebases more responsive and faster (I’m using them with the Unreal Engine 4 source build). Note: Automatic Precompiled Header Cache Quota is the amount of space you let VS use up […]
Wrote an instanced skeletal mesh renderer that can render up to a million units in UE4. Fully custom DirectX 12 rendering tech built in the engine, all GPU-based including animations, bone transforms and skinning.
For the past 3 months I’ve been busy full time with making a giant army renderer from the ground up in UE4 and it’s finally finished. It can render up to a million units 3x faster than stock Unreal Engine and is hopefully using many of the latest & greatest DirectX 12 tricks: single draw […]
The DirectX 12 compiler DXC has received a PR about a month ago that adds template support to HLSL. So you can now do this: Which is great since that’s all going to happen at compile time and so the compiler will be able to unroll the loop correctly. This, coupled with UE4’s shader permutation […]
Computes everything in compute shaders on the GPU, including LODs and frustum culling. No GPU-CPU stalls anymore, it’s faster than HISM or ISM. Since around 4.22 Epic has exposed indirect rendering via the RHI mostly because of Niagara, but this is a custom rendering component so there’s no overhead and is therefore faster where it […]
Implemented merge instancing in UE4 to render different meshes in a single draw call. Large meshes are multiple instances. Can render an entire level in a single draw call. Based on an older SIGGRAPH paper by Emil Persson of Epic Games. All the colored parts in the video below are one single draw call!
