The Witcher 4 – UE 5.6 Tech Demo | State of Unreal 2025



Check out this Unreal Engine 5.6 tech demo for The Witcher 4, running on PlayStation 5 with raytracing. This tech demo shows off the new Fast Geometry Streaming Plugin to load open-worlds faster, and we see how UE 5.6 handles busy scenes full for high-fidelity character models and visual effects like ML Deformer. Additionally, we see Nanite Foliage in action, which provides a memory-efficient way to achieve high density (and fiedelity) foliage, slated for release on UE 5.7.

The Witcher 4 is releasing at a later date.

Genuinely don't understand how CDPR hasn't learned their lesson. They pissed away all the goodwill that The Witcher 3 bought with Cyberpunk's launch, and needed to spend literal years building that trust back up and turning the game into something that, while now a pretty stellar experience, still doesnt really match what that original tech demo presented. Being explicit here- that this is something they're aiming to do, that the footage is meant to showcase what is technically rather than practically possible in UE, whatever- would go a long way to making it feel like they understood and took to heart the lessons they supposedly learned since Cyberpunk. Instead, by presenting this as a tech demo that they're confident represents the bare minimum of what a BASE PS5 CAN RUN FOR THE GAME (remember that this is 'early' footage, and something that would normally be improved upon during a game's development cycle), it feels like theyre viewing 2077's terrible and unacceptable launch as a one-time thing that surely couldn't happen again.

Of course, I'm not saying the game will look or run badly based on this footage; but this footage just ISN'T of the game.

Why the hell they didn’t use the same voice actress? wtf is that voice?

Favatar

I get that this is an older Ciri, but her voice is completely different. Kind of throwing me off.

This is 100% a fake demo. Right out of the Cyberpunk 2077 playbook. And even if the game eventually does turn out to look like this , who cares?
Ciri as a Witcher? I'll pass.

This footage, just like the one from the official UE livestream, is not 60fps; each frame is repeated.
As for the game itself, I don't expect this one to have killable NPCs or a proper crime system and I'm fine with it .

Sorry, but I'm not buying this will run anywhere near this smooth nor what they are saying it will run.

This is also what Assassin's creed Hexe looks like xd, The witcher doesn't feel anymore like a the witcher game

They made Ciri great again and the experience they had optimizing cyberpunk 2077 hasn’t gone away.

I say we give em a shot.

Yeah this video of the footage is running on the ps5 lmao

Yeah, yeah, yeah, we get it. You all worked really hard to make the horse, the bushes, and every other thing as detailed as possible.

However, none of this will matter if the game crashes every 10 minutes and the textures don't load. 🤦‍♂🤦‍♂🤦‍♂

what about the actual gameplay though? this is just animations and graphics

Favatar

skeptical comments highly understandable. Despite the fixing of CP2077, most still remember its E3 2018 demo being false.

Favatar

We all know this is fake.

They should be clear and say "we made this prerended video to show things we could achieve if the current consoles would actually have a decent hardware"

No pony muscle flexing is going to solve the actual downgrade the game will have.

Base ps5 with 60fps AND ray tracing?….riiiiiiiiggght that’s almost as believable as me saying Cyberpunk 2077 has a flawless launch. Cmon now

Games like this puts Bioware, Bethesda and Obsidian entertainment to shame, even if this game is overhyped, it's so far ahead of traditional Rpg devs

0:14 Don't lie, it doesn't look like 60 fps at all.

Absolutely incredible, I can't wait, Witcher 3 is not just one of the best RPGs I've played but it's one of the best games I've ever played, day one.
