Notes on .@t_looman UE5 Unreal Engine Optimization Netflix and Chill Video: -r.nanite.maxpixelsperedge >4 (default 1) - simplified complexity of the nanite vis buffer(stat gpu) -less is best -r.temper.sharpen 2 - 👀👀👀 -Light complexity view mode -Stat gpu / do you need all these lines? Lense flare? Just be sure. -shows costs on the gpu ranked -Mega lights / invalidating lights … sounds like virtual shadow map page invalidation. -reduce light attenuation range, overlaps, and cone(into known shadow areas) & reduce cones -setup light max actor draw distance as low as possible -Virtual Shadow Map Cache Page Viewmode Blue expensive/invalidated. -r.shadow.virtual.showstats 1(try to remove invalidated) / r.shaderprint 1 -WPO materials, will trigger light -Nanite makes WPO expensive, since you should use verts and not wpo. -Set max distance on WPO if you have to use it, for things like animations (wind/foliage) Evaluate WPO view mode, green is wpo(expensive)/“bad.” -Ensure your shadow and lighting aspects of your materials ALSO have a max range for affect. Shift+/ will reset Niagara sims -niagarasystemcounts will show how many active systems are in the world -stat Niagara / details on Niagara costs -No culling by default within Niagara, you need to enable it (fullstrum etc)or use an effect type. -low update feq may be ok on the affect type -cpu v gpu, if your rendering is suffering, and you have extra cpu cycles… or is the game thread busy and the renderings waiting? Assets: -level stats: try removing meshes that are used only once. Same for materials. Unify -nanite stats -shader bins: reduce empty -custom data doesn’t require unique materials. Single draw. -nanite all the things. Convert to masked materials from translucent if possibles… then nanite that ;) -disable collisions on meshes you don’t need to collide with or cannot get to. Same for shadows on meshes you can’t see shadows from. -showflag.nanitemeshes 0 will hide all nanite, make it easy to see what meshes you missed. -nanite fallback meshe generation have been tuned in 5.3+. Ensure your meshes are not using a 100% fallback mesh, as collision uses the fallback mesh. So simplify it. -resource viewer: figure out the size and costs of items in your level. Reduce them. -turning things off to improve performance: toggle it, see if it makes enough of a difference to you for the cost. -t.maxfps 999 -abtest : console command to toggle console actions -stat draw count -component “detail mode” allows you to hide a mesh based on the scalability setting 🧐Link in comments
