Should ZOS begin planning on rebuilding the ESO engine?

I just got excited to hear that SWOTR is going to get a massive engine upgrade. Since both SWOTR and ESO both run on the Hero Engine, the obvious question is should ESO do something similar to fix a lot of the performance and bug issues plaguing the game.

    The ESO engine is outdated and doesn't support framegen, raytracing and other modern goodies. But at least it runs on DX11 while SWTOR still relies on DX9 (which is exactly what people at Broadsword are upgrading right now).

    As for whether we can expect upgrade to the modern standards here, I seriously doubt it. That's a massive undertaking that requires serious funding and dedicated engine engineering team. These are professionals with entirely different background than the devs who design Crown store stuff. So full engine upgrade is highly unlikely to say the least.

    I dunno. Whenever people make posts about upgrading the ESO engine I feel like they have specific things in mind but just fall back on "engine".

    Are there graphical things the current engine can't do? Yes. Are those things the limiting factor in what we get for visuals? IDK. They've cited the engine as the reason we can't have capes or some types of physics things, but they've also said memory constraints are the limiting factors in a lot of animation and quantity of elements things they already could do in this engine. Would an engine upgrade would make things more efficient and allow them to do more with less, or would it just allow a lot of things we wouldn't get anyway because of other bottlenecks? I don't know.

    Personally I don't have an issue with ESO's visuals. They may not be "the best" but they are very good and satisfying. The coding related things I have issues with are bugs and performance, and I don't feel like most of those are engine related, but I could be wrong.

    First, it's a misconception to say the game runs on the Hero Engine, as I recall it was partly involved during early development but it's actually ZOS's own engine.

    Second, why would a new engine fix bug issues?

    Third, performance issues are often down to inferior player hardware - a new engine wouldn't, for example, be built to run on old generation consoles which are the cause of a lot of the limitations with the existing engine - as well as real world location - Australian players, for example, wouldn't necessarily see any improved performance from a new engine (compared with say a localised server).

    Fourth, it would represent a massive diversion of limited resources at a time when new content (in the sense in which most us understand content) is at an all-time low.

    I am hopeful they can, and they should. Honestly a new engine would allow them more legroom to address some of the big issues in PVP, but like many have said it is a massive undertaking.

    That being said with the amount of money, staff, and resources that were given to Project Blackbird for years I do believe it's feasible while also doing Tamriel Tomes and other content.

    Project Blackbird happened in better times long gone. Currently all game studios have drastically cut budgets and are laying employees left and right. This is partly due to global stagnation and partly because of the widespread AI adoption. I doubt ZOS has more than a handful of tool engineers now, if they have any at all.

    And since you mentioned Project Blackbird, that's the main reason the studio is in such bad shape now. Most of the good devs they had were fired because ot that fiasco. But lets not go into details about why this happened and whether it was fair or not, it doesn't matter anymore.

    Which is likely why, whether they should or not, it wont happen.

    They have said on stream, a few times, that there are currently no plans to rebuild or otherwise change the engine. That it would essentially be creating coding a new game from near scratch.

    Replacing the current engine on the current game would most likely take time away from new content. But, a new engine would be the first step in the development of a new game. So it depends on what they are going to do a new game or keep this game actually moving forward with new content.

    If this new "engine" comes with a turbo, I want to take it for a ride!

    edit:
    • Small update / partial engine replacement: 1~3 years
    • Full engine swap: 5~10+ years
    • Realistically: Don't worth it unless you’re starting a completely new MMO. ZoS would likely incrementally update the engine rather than fully replace it.
    Just to balance DPS, we have to wait 2 years… so messing with the engine? That would take 100 years, at least. Cause after testing, the engine will probably run backward for sure.

    If they want ESO to be a 30 year game like they said, they are likely considering some upgrades. I'm also sure there are plans for a release on the next gen consoles, at least Helix and possibly PS6, and those won't fly unless they go along with some visual bells and whistles.

    Personally I would love a change to DX12 to allow for FSR2+, but I'm not holding my breath.

    Should they? Sure. Can they? I question whether they have the manpower, expertise, or budget at this time.

    And if such a project were to take away from already reduced and at times, anemic, content releases, I fail to see how the game could continue to sustain itself in the interim.

    Yeah blackbird is is the culprit for what's going on with the game and was behind its decline. If you've seen footage of it, it's laughable that it's the reason. The director should've been canned long before.

    As for the swtor engine. I do believe saying it's getting a new engine is wrong. Correct me if this is incorrect, but aren't they just upgrading a few things and not transferring the game to a new engine? I was a long time launch player of swtor. I left 10 years ago but I'm happy it's doing goodish. Let's be frank though. It needs help that ESO doesn't need.

    Explore it as an option in the future. We have too many more important problems, like the broken state of combat, Subclassing and the fact our characters have been ruined by U46.

    Or way more options for character customization. ESO hair looks awful compared to any other MMO I've seen.

    They should have started building the game on a new engine about 5 years ago. They knew from the beginning it would have to be done to keep the game viable sooner or later, so that's what they should be doing or have done already.

    Except most performance issues with ESO are server side. It's pretty rare for the performance issue to be internet related and EXTREMELY rare for the performance issues to be hardware related. It's almost always ZOS' server or Akamai, who ZOS contracts as ddos protection etc. Performance issues in ESO are almost always server side. It's the only game I've ever seen where it's like this, but it is. After more than a decade this is undeniably the case.

    Yeah, they are trying to port to DX11. I'm still following the game in socials and that popped in the latest producer's newsletter. Also they are not switching to Frostbite. The article mentions that they asked EA's Frostbite team to help implementing the new shaders, but they are still using the old battered Hero engine.

    The way I see it is this: despite Rich Lambert's claims that ESO is a 30 year game, I do see ESO as a depreciating asset at this stage. In particular, performance is incrementally getting worse with each patch with no end in sight.

    New MMOs are getting rarer and rarer. I think the future for ESO is a fully rebuild engine that they can get another 10-15 years out of.

    Its doubtful zos will make the next 2 years let alone 30. Things are changing and games arent a priority at microsoft anymore for reasons. The game has made some money over time but is still a generally poor performer. It wont take much for the axe to fall again. Theres no point to upgrade the engine when you can see the sun setting. If i was workin at zos and i wasnt in the protected crowd id be moving on lol. Not that theres anywhere to move on to.

    Waiting years for bug fixes, I won't get my hopes up. For longevity it probably should be, but the game has aged well graphically. Older set textures could use overhauls.

    I believe that is what I read too. It is a truly fantastic game. It was never gonna be the wow killer it was billed as, and it'll never be forgiven by some gamers for killing SWG (true or not) I thought about getting a new Pc to play it, see what I missed in 10 years. Unfortunately it's not a lot. It was the reason I left. Woefully neglected. A cautionary tale of when a game is popular, loses steam after some years, moves to a battle pass and just kinda exists in limbo.
