1.0 What It Actually Does
Render Diagnostics is essential for troubleshooting your scene. Use it to profile performance or identify issues with Aliasing, Artifacts, Nanite, and VT Shadows.
TSR RField Overview & TSR Overview
These two switches show you the overview of TSR's main debug data, to see if flickering is from TSR, or if you have noise, sampling issues etc.
Render Diagnostics Gives you:
- DrDebug reads Real VRAM, not Virtual Memory. Getting this data normally requires external tools like Pix or RenderDoc because Unreal doesn't surface it easily. DrDebug puts it directly on your screen.
- Texture Pool Usage.
- Trace Scene
Scene Tracing/Profiling
In the video Below, when you click on Trace Scene Button, you see a red blinking square on the menu's toolbar and on the button, which means Unreal is tracing your scene (DrDebug goes in a frozen state on purpose to give you accurate profiling) When you toggle it off, unreal automatically opens the profiling you did, you don't need to look for it.
Nanite Overview
None Unreal Engine Users know Nanite Overview, the necessary Overview For nanite customised to work well for DrDebug's UI
Anti Aliasing Methods
It allows you to switch between AA methods without overwriting the changes to the project, as soon as you click something else it'll revert to default changes silently. It helps with Aliasing issues and Artifacts.
Render Resources
The switch opens/closes Render Resources which is very useful for performance & optimisation & seeing what's going on in the memory

VT Shadows
VT Shadows debugging made easier, see what's going on on your VT Shadows, you can also switch between lights using the two buttons Next Light, Previous Light to preview the influence of VT Shadows on each light seperately.
