PS4 'isn't quite as powerful as Epic was hoping for,' Digital Foundry reports

 

Although Epic Games publicly has high praise for PS4, the wizards at Digital Foundry have determined that maybe "the next generation of console hardware isn't quite as powerful as Epic was hoping for." How did they come to this conclusion? By comparing the first Unreal Engine 4 tech demo, running on a PC equipped with an Nvidia GTX 680, with the latest presentation running on a PlayStation. By analyzing the two, minute differences where the PS4 comes short can be found.

"The biggest casualty is the omission of real-time global illumination, which produced some really impressive lighting in the original presentation," Digital Foundry writes in their report. "GPU particles are fewer in number, depth of field has been significantly retooled and isn't quite as impactful on PS4, while object-based motion blur appears to have been removed. The flowing lava effect had real depth and texture to it in the original PC version - on PS4, it's significantly flatter."

While PlayStation fans will undoubtedly be disappointed in the analysis, Digital Foundry does note that the differences can be the result of the relative newness of PS4. "The DirectX 11 API is very mature while the PS4 tools and APIs are still in their initial stages of development--it's going to take time for devs to fully get to grips with the new hardware." Thankfully, being based in x86 should make development on PS4 mature much more quickly this time around.

PS4 not true 8th gen confirmed.

When did Epic say that, exactly?

That article is misleading and missed something really important in Digital Foundry's analysis.

A nice update directly from Epic themselves:


Update: Brian Karis, senior graphics programmer at Epic Games adds some more insight in the comments below, explaining some of the more obvious differences - particularly in terms of the very different lighting schemes. At the technical level, the two demos are closer than it seems:

"The biggest changes actually came from the merging of two separate cinematics, the original Elemental and the extended Elemental we showed at PS4's launch event. Each had different sun directions and required some compromises to join them. This resulted in some major lighting differences that aren't platform related but were due to it being a joined cinematic. Another effect, in the original you could see the mountains through the door where in the merged one we made the view through the door white since the mountains outside were no longer the same. Same deal with the mountain fly by. The old mountain range doesn't exist in the new one. These changes from the merge make direct comparisons somewhat inaccurate.

"Feature wise most everything is the same, AA resolution, meshes, textures (PS4 has tons of memory), DOF (I assure you both use the same Bokeh DOF, not sure why that one shot has different focal range), motion blur.

"Biggest differences are SVOGI has been replaced with a more efficient GI solution, a slight scale down in the number of particles for some FX, and tessellation is broken on ps4 in the current build which the lava used for displacement. We will fix the tessellation in the future."

So yeah, this article is bullcrap, and fishing for clicks at the expense of integrity.

Does this mean the PS4 will be cheaper? That would be awesome.

Here a little quote I want for those to keep memorize in your head for this coming next gen.

Article seems misleading.

I doubt epic ever expected a console to match PC. No matter what buzzword marketing says here or there.

It still seems like a case that SVOGI was what they were hoping for this coming gen.

No it's not. It's a perfectly valid conclusion to draw when you realize what features are missing from the PS4 demo compared to the PC demo, and your quoted statement by Epic shows they were unable to deny that. Instead it confirms exactly those missing features that Epic, just like all gamers, had high hopes for:

* lack of SVO global illumination 

* and less particles on the PS4 version

It may still be impremented as the toolkits evolve and become more refined and optimized. Who knows. But if that's all that is left out, no biggy. The other lighting solutions can still look really incredible.

uh oh! ..

Anyway ... again why are people comparing it to a PC.. LOL dafuq!
