Cyberpunk 2077 director says studio's switch from REDengine to Unreal Engine 5 'isn't starting from scratch'

Cyberpunk 2077 marks the end for CD Projekt's REDengine, the in-house technology that it's been building on since 2011's The Witcher 2. Last year, CD Projekt announced that its next Witcher game and other games going forward—including Cyberpunk's sequel, codename Orion—will be developed with Unreal Engine 5.

In a recent interview with Cyberpunk 2077 director Gabe Amatangelo, I asked about that transition to UE5, especially in light of the cutting edge tech the studio has continued adding to Cyberpunk 2077 (it's the first game to build in Nvidia's new ray tracing Ray Reconstruction, for example). Does all that work essentially die with 2077?
"It isn't starting from scratch," Amatangelo said. "A lot of times when you build these things, like Ray Reconstruction, there are a lot of methodologies you can apply to new engines. Learnings and the strategy of setting up the architecture. And when you look at the things that Unreal does well, the things that REDengine does well—there are some similarities and some gaps, but the brilliant engineers are like 'with all the stuff that we know you crazy creatives want to do in the future, there's less of a delta here. Let's strategically shift to [Unreal Engine 5]'."
I asked Amatangelo if he could point to any specific challenges that the dev team faced with REDengine that would be easier with Unreal. He didn't want to give away any secrets from Cyberpunk's sequel, but said that at the high level it's "refreshing" to be coming to Unreal with what they've learned while developing 2077 without having to start the process of "rebuilding" their own engine for the next game.

"Likewise there's some things that REDengine does better than Unreal [that] we're working with Epic to basically bring to that engine as well. So it goes both ways… It's about economies of scale: you can obviously do all these amazing things in both. There's so much nuance behind it, but it comes down to ways to approach things to be able to do more. Not necessarily better—it could be just as good—but do it more. It's a scale thing sometimes."
The Cyberpunk team is ready to start developing the sequel, but it likely won't be the first game we see from CD Projekt built on Unreal Engine 4. That's more likely to be The Witcher 4 (or whatever its name ends up being), announced last year.

Say goodbye to multiple options to completing quests
Huh? Why would that be based on the unreal or REDengine? I swear people have the weirdest idea of that engines actually do. You could add multiple options for completing quest in literally any code base

As good as cyberpunk looks, the game still feels like it held together with ducktapes. Still so buggy and janky. Im glad they move over. They can do insane visuals in UE5 too dont you worry with hopefully less bugs

who cares, i'm not buying shit from CDPR until they prove themselves again with a good game.

CDPR prove themselves?

Mate even their expansion packs review better than most games.

Hell they made a game based on a mini-game from one of their main games and that game has a metacritic of 80+

Even Roach Race is actually a legit fun game.

How you gonna sit here and say they need to prove themsleves when theyve released nothing but bangers.

In the case of Cyberpunk their expansion pack has reviewed better than their main game, too. So not really sure what that is supposed to prove. Roach Race is legit fun.

Sad to see them abandon Red Engine cause it always looked so good and ran quite well. I hope their UE game isn't a stuttering mess like so many others are.

Just stay with your current engine looks amazing. EU5 is a stutter resource hog.

Their current engine has amazing rt integration and multithreading (much better than ue5 or pretty much any other big engine) but I think it went out of control after Witcher 3 and become broken in many aspects. That's why cyberpunk was so buggy and it took them some months to patch it up (base game 1.0) to really playable state. They probably expect much smoother development with ue5 and epic help.

Hope I can afford a PC by the time their next game is out because if it's UE5 it will probably run like crap on consoles.

RED Engine runs so much better than UE5 on my machine, it's not even funny, and it looks miles better too.

I understand that CDPR needs to have easier authoring tools and onboarding, but I'm not sure if the end result will be better.
I didn’t know current CDPR games are already on UE5 to compare between the two.

Man, prepare for pain. Have yet to see a decent running AAA UE5 game. I guess by the time Cyberpunk 2 comes out somewhere in 2030, we will all have much faster systems at least.

Immortals of Aveum runs well considering what they’re doing at 60fps. They should have probably given consoles a 30fps option but considering the geometry and lighting it is pretty impressive. Art style might not be to everyone’s taste but it is legit pushing a lot of calculations into each frame.

Haven’t played it but it’s been pretty piled on for being fairly low res. Issue is CPU/GPU cycles seem to being spent on stupid shit resulting in bad performance.

You have yet to see a AAA UE5 game period.

While Ascendant are/were a studio filled with talented people, I wouldnt call them a AAA studio, we have to wait for the first batch of AAA UE5 games to come out before we can judge the engine in anyway.

Hell 5.3 just came out and alot of the experimental features are only production ready now, while a bunch of other features are actually still experimental, which would require having some pretty hectic engineers in place to make sure said features are stable.

And CDPR have already stated they are extending UE5 to fit their needs, few if any AAA developers use Unreal in its "stock" form, it has a lot of bloat thats not necessary and alot of features that devs need for specific projects.
Im sure their build of UE5 is very different to the stock version, just like The Coalitions build of Unreal Engine 4 (The Fenix Engine) is substancially different from UE4.xx.
Hell even Nether Realms build of UE4 seems to be vastly different to the stock version.......its probably gonna be the best looking fighting game of the generation, until Mortal Kombat 2X.

Do you guys realize we are at least 5y from Witcher 3 ?
Till then we will have new consoles & new PC's who can eat UE5 for breakfast.........

I hope what they mean is that they will reuse Night City in the sequel. It’s such an amazing place, just expand upon it.
That would be the smart move, at least for the next immediate sequel. But I fear creative egos might get in the way...

Bs. All of it. If these engines are so similar it would make absolutely no sense paying the hefty licensing fees for UE5.

They want an engine that works, people know and doesn’t lead to a games broken launch , needing a massive patch three years in the works to fix things.

Of course they will all be modified and expanded, extended and use bunch of different middleware. Considering the state of games right now that are coming out I am dubious any of they will be well optimized.

Can you imagine engineers of an in-house engine deciding that UE5 would be best to switch to? I highly doubt it, they have their jobs to protect.

It is l suspect management driven.

Was it based on the delays and subsequent issues with previous generation? I'm sure that played a part.

I don't think they will have it easy with UE5 but l suspect Amatangelo will be a driver to ensure the release goes smother than before.

Hopefully they could speed up the development time with ue5. They struggled big time to upgrade and develop features for cp2077 with red engine 3 and that likely takes away so much of their time with a lot of unnecessary costs. Also a lot easier to hire people that knows the engine.

Hopefully they can make their world's feel alive with this switch, somehow Witcher3's world felt more alive than Cyberpunk which tbh just looked dead, gorgeous but dead
