KDC1 in KDC2

A few highlights riding through the old map and exploring the church.

Still lots to fix, but pretty cool seeing it running in KDC2.

@TheKimbol Thanks

Spent pretty much all day trying to optimise the rendering and get rid of the hitches when moving around the world. 😂

Ended up changing how vegetation is streamed, reusing GPU resources, reducing shader compilation and even patching parts of Three.js to cut down unnecessary allocations.

Also changed how the world is generated, with proper watersheds, rivers and more natural forests.

Still getting some frame spikes, so not quite there yet haha.

All running in the browser using WebGPU.

@ChShersh Haha

@taoofdev You are welcome to. Its all open source/MIT

@taoofdev It doesn't work, only for PCs atm

The voxelization is done at runtime in a Web Worker. It uses spatial indexes to grab just the trees, grass and objects overlapping the area being processed, rather than going through the entire world.

The voxel data is used for lighting, so it's a bit different from Minecraft-style chunk meshing.

The GPU uploads are split into smaller pages with frame budgets, and stale jobs get cancelled when they're no longer needed.

I've also got separate workers handling grass generation, geometry merging and other preparation work.

[SamG @SamGCoder]

Been working on this. 16km² in the browser: Three.js/WebGPU, voxel baking, cached HLOD, paged GPU uploads + stale-job cancellation.

Live day/night walk. Still sorting streaming hitches.

@Elaea_Genshin Maybe, I could have a look at using map data to create the terrain.

Modern day Prague or 1400s Prague?

[SamG @SamGCoder]

@Nachoestevo @Elaea_Genshin Nice work

@gregsometimes Nice work!

[SamG @SamGCoder]

@btn0s Is your project open source?

[SamG @SamGCoder]

@Ilhan @grok what is ICE and what are the dangers on "Abolish ICE" Not Reform but Abolish. When was this agency established and what motives does "Rep. Ilhan Omar" have to ask to Abolish.

[SamG @SamGCoder]

@btn0s Nice

[QNDZY @QNDZYcom]

No, this is not real life.

This is Crimson Desert running at max settings with RT and DLSS 5. We have officially achieved photorealism in gaming.

[SamG @SamGCoder]

@josephofiowa Literally just screenshotted.

Using the Web Chat?

What more do you want

[SamG @SamGCoder]

@BreezeOg1 @grok go through the code to find out where the remaining hitches are from

KCD1 -> KCD2

Decided to take a ride around Rattay at night. 😄

Actually, quite nice just riding through the empty streets with the torches lighting everything up haha.
