Unreal Engine 5 - Virtual Shadow Map Performance (Explained)

[@wilismatrix9847]

when using VS with a scene that have a lot of folliage it is recommnaded to disable Coarse Pages via those commands r.Shadow.Virtual.NonNanite.IncludeInCoarsePages 0
r.Shadow.Virtual.UseFarShadowCulling 0

[@unrealdevop]

Thanks, that's very useful. I was unaware you could do that.

Holly shit, Batman is doing an Unreal Engine tutorial :0

Thanks Adam Jensen, very cool 😎

[@unrealdevop]

Lol. Yeah the environment looks really great for sure. Wish I could take credit for it but I can't. Don't look bad under Lumen Lighting either.

[@ChaosFairy_]

Thank you, I needed it!

[@unrealdevop]

Yeah for sure.

[@alexanderkartashov8776]

that's very helpful, i kinda knew this vaguely but better understanding is good to have.

[@unrealdevop]

For sure, glad you found it helpful

[@imercutio]

Good explanation, thank you.

[@unrealdevop]

Yeah, for sure. Glad you found it helpful.

[@schmoborama]

Brill, thank you

[@ydvisual5530]

Thanks Mr. Unreal DevOP - fantastic - after seeing this video I have been inspecting ProfileGPU all day today ! Verryyy useful info !! thanks again!

[@nicwhite2071]

Thank you for the explanation!

[@unrealdevop]

Glad you got something out of it.

[@Alaabale]

Thanks helped me get double FPS what actually funny that I am using the same map

[@unrealdevop]

Yeah it's a pretty popular asset.

[@GarfSnacks]

Much appreciated, thanks for the explanation 😁

[@PhylJoy]

Great video!

[@unrealdevop]

Thanks!

Did you create this world? Its beautiful

[@unrealdevop]

It's Dreamscape Nature, by Polyart Studio and yes, they did a very good job on this.

[@ing_frantisek_mohykan]

how can you get 130 fps on that crazy beautiful and large scene?

[@unrealdevop]

It's just well optimized and it's not an exceptionally large map.

[@deanthedev]

Mine is totally opposite. If I were to change "Shadow Map Method" to "Shadow Maps" I'm losing insane amount of FPS. It's set to "Virtual Shadow Maps" now.

[@unrealdevop]

Yeah so from my understanding...Virtual Shadow Maps Require an Extra Render Pass for Non-Virtualized Geometry....
However, Regular Shadow Maps require an Extra Render Pass for Virtualized Geometry.
That's my understanding at least. So if you have a lot of Nanite in the Scene and your using Shadow Maps it could actually drag performance down.

[@deanthedev]

@@unrealdevop that's right. It's full on Nanite.

[@unrealdevop]

@@deanthedev Yeah I was doing some profiling once and noticed that the same Rasterization was causing a Spike when using lots of Nanite with regular Shadow Maps so I assumed that was probably the case.

[@unrealdevop]

@@deanthedev Well not the same Rasterization but one related to Nanite instead of Non-Nanite

[@mrxcs]

What is the name of this map on marketplace?

[@unrealdevop]

Dreamscape I believe

[@Fikarblackproject]

Bro, how to make the game into local server?, so my friend can join into the game in web broswer? They dont need to play from main package thanks🙏🏿

[@unrealdevop]

I'm assuming your talking about playing the game from a web browser. I believe web-based support was last supported in 4.24 or 4.23 I don't remember but they abandoned that for whatever reason and removed it.

[@Fikarblackproject]

@@unrealdevop so, we cant export anymore to website in unreal 5? cause i cant use datasmith in 4.23

[@unrealdevop]

@@Fikarblackproject They removed the ability to compile to HTML5 some time ago, it's not something I see them bringing back

[@unrealdevop]

@@Fikarblackproject You could use an older version of Unreal, or consider switching to Unity. I believe Unity still supports this.

[@Fikarblackproject]

@@unrealdevop thx man, I already using UE 4.23 , it’s. sooo bad graphics for game 😂😂 no lumen no raytrace, trying so hard to get good lighting
