Highly dangerous of the PS people to build non-deterministic performance into their console. Developers who try to push every ounce of power out of it will hate it. edit: Maybe deterministic isn't the correct word. What I mean is that you can design a physics system that you can ensure runs on the PS5 CPU. But then the graphics boys make an upgrade and suddenly some power is diverted to the graphics and the physics s…

> Developers who try to push every ounce of power out of it will hate it. How common is this though in an era where most releases are multi-platform?

The PS still sells itself heavily based on console exclusives (Uncharted, The Last of Us, Horizon Zero Dawn) that are ostensibly well-tuned to the hardware. Guess we'll have to wait until HZD's makes it to PCs to see how easily it's ported.

I always wondered if that dinosaur was using the 2MB of memory in the final retail unit, or 4MB often seen in arcade boards using the the PS1's technology.

I could swear I “played” it when I was a kid off a PlayStation magazine or Pizza Hut demo disk on a retail (well modded) unit

I think it came out on a demo disk at some point. You got to move the dino about and maybe the light source? It's been a long time!

Wow, we'll soon be down to only one game engine. Crytek has financial worries. Plus it's the most difficult to use, because it's almost all C++. Unity is very accessible thanks to C# scripting, but has bug issues (and no source code). Unreal Engine looks amazing, is cheap or free for indie studios, and has source code included. If they can make UE slightly easier to develop for, they'll dominate the market.

Both Unity and Unreal Engine offer their source code on Github... Both engines have bugs, and one of the biggest complaints about Unreal Engine is that any feature not used by Fortnite is half-baked until Fortnite uses it. With Unity, the biggest complaints are about the relatively transitory lifetimes of some of their biggest-marketed features, like rendering pipelines or networking code.

No, Unity only has the C# part on GitHub, but it also has a huge proprietary C++ code base.

I've been wondering for a while Unreal doesn't just make the Unreal Browser. You download and install it. Then you give it a URL, and it streams down a map, and downloads DLLs containing behavior custom to that map. While you're in a map, you can walk through a portal to another map. Or you can just keep moving in a direction, which streams more and more map. If you're in a multi-player environment, you connect to a…

How do you make money from this? Who would buy it? Why would anyone use it? Is there a point beyond "this is a cool thing", which is pretty well captured by Roblox and Second Life and VRChat

1) How do you make money from this?

How do you make money from anything on computers? With Ads, with Paid Memberships, Paid Access to content.

2) Who would buy it? Why would anyone use it?

Isn't that kind of like asking "who would buy the internet? Why would anyone use the internet?"

Remember when Chromebooks were announced and everyone laughed because it's "just a browser?!"

Well, imagine if you were browsing, except it looked like Unreal engine when you got to 3D content. Rather than looking like crappy WebGL content.

3) Is there a point beyond "this is a cool thing", which is pretty well captured by Roblox and Second Life and VRChat

Do you think Roblox, Second Life, and VRChat look as good as Unreal Engine 5?

Would you enjoy playing content in Unreal Engine 5 without having to install an entire game first?

Nothing is stopping them from doing this. At the same time, nothing is motivating them to do this either.

Isn't that kind of like saying that "we can all just keep using Postscript files. There's no need for this HTTP / HTML thing. Why would I want to stay in the 'browser'? I just use FTP to fetch content, and use my favorite Postscript renderer to view content."

Yes, I distinctly remember rotating this model around on an original PS1 many (many) years ago.

> you can download and use Unreal Engine to build games for free as you always have

That's a very stretched-out definition of always. Unreal used to be one of the most expensive, if not the most expensive, game engines you could license. It's been only few years they adopted this free model.

In the past, I have always looked at Demos from Games and thought this is very good and getting close to movie quality. But that "close to" remained "close to" for quite some time. Even though It is improving every year but you can still tell it is gaming graphics. Even if some of the shots are not real time and pre rendered, they are still gaming like. That Unreal 5 Demo was the first time ever I thought this is Hol…

At the risk of sounding a bit negative I personally find that graphics have plateaued since about the PS3. Sure, there are more polys, sure, there are higher res textures, sure, there are more complex and dynamic lights. But you don't really have the kind of gap we used to have between, say, the PS1 and PS2 for instance. Diminishing returns and all that. The problem is that, in my experience, this eye candy only matt…

I find that the best PS4 games look and play markedly better than the best PS3 games.

I am always skeptical of tech demos like this, but if Epic has truly created a way to show full quality assets at runtime without manual LOD / optimization, then this is going to be a huge process improvement for game development. Same goes for this lighting. Baking lights is such a burden, if they can simply do all of this at runtime then making beautiful games just became that much easier. They also bought Quixel,…

Don't you still need to do some of that just for file size and data transfer, if nothing else? In the demo they said it had hundreds of billions of triangles. Google tells me you can get down to 18 bytes or so per triangle, but even if we assume a lower bound of just three bytes per triangle (amortized storage of 1 vertex per triangle of an x,y,z point), we're talking about on the order of terabytes to just store that scene, right?

For all the advancements the demo is still essentially monochromatic. As I recall this is done to avoid the difficulties of rendering how two adjacent differently colored objects bleed their colors onto each other. No color - no bleeding. I'd prefer color over pixel accuracy.

That my reaction to this recent UE4 demo. The whole world is monochromatic, and this seems to be an adaptation to the limits of the technology.
