Tip: Improve real-time preview responsiveness in editor

You can add the following virtual texturing related CVars and settings to your DefaultEngine.ini to improve GPULM’s VT-based real-time preview responsiveness:

[/Script/Engine.RendererSettings]
r.VT.MaxUploadsPerFrameInEditor=128
r.VT.MaxContinuousUpdatesPerFrameInEditor=128
r.VT.PageFreeThreshold=4

[/Script/Engine.VirtualTexturePoolConfig]
+Pools=(Formats=(PF_A32B32G32R32F),MinTileSize=0,MaxTileSize=0,SizeInMegabyte=512,bEnableResidencyMipMapBias=False,bAllowSizeScale=False,MinScaledSizeInMegabyte=0,MaxScaledSizeInMegabyte=0)

These settings should make the viewport update faster especially when turning camera.
