There are lot’s of things we’ve had in it’s place over the last year or so, which IMO are more important globally. Sequencer, Planar Reflections, Capsule Shadows, Contact Shadows, Improved Character Shading, New Animation Dynamics, Geometry Tools (much needed), Better AO, SLI Support, Forward Renderer for VR, Niagara, Drawing Materials to Render Targets etc. Along with all of the tiny optimizations that squeeze the last few milliseconds out of the Renderer and let things like Paragon on PS4 be possible.
Epic just have other priorities at the moment. We’ll get DGI eventually. Plus, i’m willing to bet it’ll sh*t all over the competition when we do. DGI is always going to be about trade-off’s though.
The thing is though if they have to create lighting for low-end systems then it makes it not worth the trouble to use a dynamic GI for the more powerful hardware
By the same token you can say “why make LODs and use various optimizations for a game to run on lower end systems”. Yet, that’s what all games have - bunch of settings to allow game to run on crappy hardware. Lighting is no different.
Crysis 3 used Cryengine’s old GI which honestly wasn’t anything great and made very little difference at all. However, their new GI (SVOTI) is working perfectly for both outdoor and indoors while having a very high frame rate. New games being developed by Cryengine have real time GI. It seems like only as soon as you go near UE4 domain a good real time GI becomes a big red no no. I wouldn’t be surprised though, ShadowDepths already have unnaturally high cost that leaves little to no room to add the cost of a real time GI.
Managing two lighting scenarios ruins one of the big benefits of having dynamic GI which is not having to do a bunch of lighting setup, if you have to make it look good without dynamic GI then there’s no reason to implement dynamic GI since that just makes more work with little benefit. Having dynamic GI isn’t just a simple quality setting like LOD’s.
And sure, that’s running Crysis 3, but doesn’t have shadows.
Well, many games have option to turn off shadows. And people with lower end hardware do turn them off. So, I don’t see how it’s relevant to dynamic GI. Turn it off too if you have that weak of hardware.
The video shows Crysis 3 running on a low end machine but it doesn’t look good, on the older systems they have to at least make it look at the level of what the games currently look like. If you have to bake lighting for old systems then it’s not worth the trouble of implementing a dynamic GI system. It’s not as simple as just flipping a switch. Since UE4 still has to support the regular Xbox One the new Scorpio doesn’t mean they can add stuff like dynamic GI that won’t work well enough on the old system.
Let’s be fair and look at it as a tech, not a fancy graphical specific to a game. Almost every engine out there has some sort of real time G.I. May it be built in like SVOTI in Cryengine or rely on plugins or third party solutions like Enlighten. It’s the direction the whole industry has taken except Epic and Epic did the exact opposite by removing SVOGI instead of improving it which is exactly what Crytek did and now has the best fully real time GI a game engine has ever seen.
Real time GI is one of the many many features a game engine can have, it’s only ignored by Epic for so long and no work is done in that area. It’s nothing impossible or worthless. It literally saves people time more than anything else would.
I promise you, once you get your hands on a high quality real time GI with insanely good performance and you no longer need to do lightmaps for hundreds of meshes and wait hours/days/weeks for lighting to be built, you won’t go back to baked lighting unless you’re forced to.
The argument not working on dynamic GI because of performance issues is outdated as hell “by the way, i think they are no performance issues at all with the current console and PC hardware avaiable these days”. Not working on dynamic GI ? But putting in so much effort in VR? Which barley any PC can handle… And beside of that, VR is like a non profitable game market so far.That makes no sense… The Hardware was even strong enough with the last generation of “graphics cards” to handle Dynamic GI. There has to be a different reason why EPic is not working on any dynamic GI solution so far… Actually before they start to work on dynamic GI they would need to fix the extremly bad performance for dynamic light in UE4.
I mean VR is a really cool thing no quesation about that… But you need a hell of a machine to get VR run well…
Dynamic GI is a much easier task for current and especially last gen PC Hardware… You dont need a GTX 1080 to run a game like Kindom Come which is using Dynamic GI.
I’m also reading all the time in forums… Not has a good PC… A good graphics card… This is Bull**** Thats why we have game graphics options, if your PC cant handle a game… go lower with the settings.
What are the best sold games ? Right, mostly all the Blockbuster triple A games… Are they known for bad graphics ? Not at all! You usually need a tough PC to play games like Ghost Recon Wildlands, The Division, GTA 5 etc… But players are still buying this games… hmmm crazy world.
