Ambient occlusion for dcs

[Fri13]

as for RTX, it's simply a new Gimick launched by nVidia, any GPU is capable of hardware based light rendering. Most games already use it in shaders.

 

That what made it sad thing, that it was so hyped to sell RTX cards while you didn't need it. But what else is new in the business of graphics where every 3-6 months there should be a reason to buy next new thing?

 

And maybe most annoying thing is how these big companies purposely starts to block each others and divide the customer bases by idea to lock them to their products and services, like how long it took to get now every G-sync monitor to be Freesync? Completely unfair thing that what Nvidia did for the industry. And same thing can be said on higher level like Apple not simply already adapting the USB-C as their main connector, and before that the Micro-USB. Since 2009 the EU had the optional requirement to standard gadget port and it was Micro-USB, but it was not required. But it worked so well that we moved from 30 different charging connectors to just three main ports (Micro-USB, Mini-USB and Lighting). Now the EU is planning to make it a law that all devices should have just the USB-C port. And of course Apple is fighting all it can against it.

 

Sure lots of things has changed in the hardware wise, but we are still in a mess when different companies are competing against each others instead cooperating.

RTX "fake"???:shocking:...ray tracing is, in fact, the best and the only way to do, with a high degree of accuracy, indirect lighting based on the real light physical behavior (actual displacement of the photons) instead of using rasterization.

 

I didn't say that light tracing is fake, but the SSAO is fake. It of course depends how you apply AO but it is generally very fake looking effect that just is used to be fixed with some other fancy effects.

 

So if you read my point, I say that we should use a ray tracing to the cockpit but not use AO for the terrain as last thing we need is huge shadow halos around vehicles, forests, buildings etc so they will "pop-up" even more.

 

And it wouldn't take at all so much resources to apply ray tracing for the cockpit, unlike if it would be cockpit + world.

 

We already have great shadows and lighting effects for the world in DCS, but the cockpit is little so so at moments. Like the shadow edges or the contrast. Does work very well, but it can be made better. And that is why ray tracing shadows from the canopy etc, could make huge difference.

 

If ED can find a way in their new graphics engine to improve the cockpit shadows, I am all in.

 

Like seriously, the current state as

 

It is no way BAD. But when you get the shadow edges like you can see around the canopy "towel rails" etc, it is like 128px shadow maps compared to rest of the cockpit that is like 1024px shadows.

 

And the cockpit shadows around different buttons, etc, they are actually very good.

 

 

One last thing I would like to see is fake shadows around all the buttons, knobs and switches.

Well, a full global illumination calculation would be amazing but sadly that wouldnt be feasible from a computational performance point of view, thats why AO was invented as an aproximation to how indirect light would behave...so imho, having AO is waaaaay better than not having anything to represent indirect light dont you think?, also it shouldnt be too hard to implement.

 

The VR would be the highest impact receiver for extreme raytracing, but so would be the egos of many display users who believe they need to play everything at 144 FPS anyways (those people should seriously move back to CRT monitors if they care so much about refresh rates).

 

But AO (depending how implemented etc) is just fake, bad looking. Same thing is with raytracing if it is not done properly, it will look bad, or you don't even notice it all. Like most games today are implementing it such way that you need to quickly swap between it enabled and disabled to notice something in some very specific parts of scene like reflection on puddles or how a glowing fire casts on some surfaces etc. Just gimmick.

 

ED is doing new graphics engine, and they have good experience by what there is in market and what they want.

RTX may be indeed a gimmick for now, but ray tracing definitely adds to the realism of the scene. I am currently playing a game that uses it for global illumination and it really shines at times. For example, when you're inside a building during daytime, the sunlight is reflected on a white window frame and appropriately lights the nearby wall, while keeping areas away from direct or indirect light sources dark. You simply don't get this with SSAO or HBAO.

 

And reflections might be a small and unnoticeable thing in most games, but inside a cockpit, with all the gauges, displays and canopy, they are a constant and important element and one thing that we really lack right now.

 

AO and SSR are good short-term solutions for now that I'd like to see, but it'd be a shame if ED's next engine didn't support any kind of ray tracing, especially if it's released after 2020. It seems that the supporting hardware is here to stay, since both NVIDIA and AMD are including it in their high end cards and the next console generation will include it as well. And it may be computationally expensive now, but it's going to become much more manageable as it matures. Right now, a lot of us have RT cores that are just sitting, doing nothing at all and as time passes, that number of users will just grow.

Yeah, there is a SSAO entry in the options lua...thanks, will check it out :thumbup:

 

Hi,

 

could you give feedback regarding this please? it is worth to change/enable SSAO options.lua?

 

(I fly in VR)

 

Best regards,

I tried this but it didn't make any difference

Yeah, same here...it does nothing :(

[Harker]

Absolutely nothing? The one time I tried it, I think I did notice some very small changes and my GPU was utilized a few % more as well. I remember that it was too subtle (some more shading around switches and buttons) to bother keeping it on though.

As far as I can tell I didnt notice anything inside the cockpit or outside...not any higher gpu usege either.

 

Thank you.

 

You are welcome mate!
