Ray Tracing

Strange! Everybody here seems to be against choice!
I want to be able to choose to use RT. And why not [rhetorical].

The argument against RT - that it will only be of use with the 20xx and 30xx cards - is specious.
The point of the software is that it should be compatible with as wide a range of hardware as is reasonably possible.
Otherwise we are all in trouble!!!

Understandable. The cloud update brought flickering skies. An RT update then brings flickering ground for all lower than 20xx? :rofl: :wink:

Well, it is good that we all have a space where we can express our opinions.
And I agree that Cyberpunk has managed to eat itself. But that has nothing to do with RT, per se!

So to balance your opinion on the subject:
I HAVE played games where the RT looked just fine and enhanced the game no end!

And as for time wasting! That accolade has to go to VR.
To impliment VR before sorting out the core sim and the SDK is madness.

Raymond, the brother who didn’t want to live on Tracing Island.

Where is there going to be Ray Tracing in a flight simulator?
Sunlight reflecting round the cockpit?

Ray tracing is already enabled in the sim. If you look at the file called UserCfg.opt
{SSRaytracedShadows
Enabled 1
Quality 1

But whatever it does, it does an awful job.

There are visible reflections in shiny surfaces such as:

  • the outside of your plane
  • the windows of your plane
  • mirrors on some planes
  • the windows of buildings

It’s not actually an unreasonable thing to want as a nice-to-have, and there already are reflection renderings for some of those things, just not as good quality as fancy ray tracing would do.

Definitely not essential, and I won’t mind them putting it off while working on other things, but I’d be happy to have it.

A passing UFO.

So this is the kind of artifacts you can see with the current reflection rendering, which appears to be done in screen space and is limited to reflecting objects which are not obscured for direct view:

This ‘wedge’ is bitten out of the Rock of Gibraltar because of the angle of the edge of the window; the bits that would have been reflected in the sea are obscured on the camera view so they’re not available in the buffer when pulling out pixels to reflect.

My understanding is that ray tracing solves this sort of problem by using optimized units on the GPU to calculate which object to reflect without being limited by what’s already been rendered; from there the reflected pixel can be re-rendered, creating a more accurate and consistent reflection.

So yeah, I’d love this to be supported! Might even work ok on my RTX 2070. But if it’s not done in the next update I’m not going to be super bummed; it’s a nice to have that improves realism and immersion by avoiding a visible rendering artifact.

Not necessarily
 ray-tracing on my RTX20xx card works just fine so far. No slide shows here. Might depend on how well the devs can optimize things, or what CPU you have, too?

What I mean is that on RTX2000 series you’re losing about 1/2 your fps if you enable full ray tracing. For most people with MSFS, that would drop them down into single to low double digit frame rates. Like it or not, the 2000 series are 1st gen ray tracing, just like the AMD 6000 series. Their performance at that kind of sucks. I have an RTX2080, and I wouldn’t even bother using ray tracing on anything since it’s just too much of a performance hog for my liking. With an RTX3000 series card though, that’s a different story.

The game, “Control” with real-time ray tracing and max or close-to-max graphics runs smoothly on my RTX 2060. I doubt I lost 1/2 my framerate, but I’ll try to check sometime. Still, I get great framerate, whatever it is. Do you have a decent amount of RAM and CPU?

Not saying every game does or will run as well, but as developers perfect coding of the ray-tracing tech over time, I’d think it’ll get better and more efficient, in general

Besides, Flight Simulator has so much tech in it, it really seems built to future-proof itself for years to come. Adding real-time raytracing will just do more toward that end. So, as the playerbase upgrades their equipment over the years, the game will be waiting for them

PS4s and XSXs have RT raytracing capabilities, so games are going to do it more and more anyways

Seeing RT raytracing on the glass over cockpit readouts, in the glass of the cockpit, in water, building glass
 along with realistic lighting bathing objects everywhere moreso than they currently do probably, will be great

I think ray tracing would be a good idea when iluminating the aircraft (not the entire world/scenary), but only if DLSS could run together.

It will certainly bring better reflections. Currently its not so good.

Cyberpunk maybe bad on a lot of things but their RT implementations is one of the best. I would say other game that have comparable RT implementations is Control. Although Control is a mostly closed space while Cyberpunk is a city. I can’t be compared to RDR2 in terms of RT since the scene are very different.

I’d rather play at 720p with ray tracing and DLSS than 4K HDR with these awful reflections, they’re making this game unplayable for me. I can’t believe everyone here is okay with it. Everywhere I turn reflections just pop in and out of existence.

I don’t see how the reflection artifacts make the game unplayable?

Good luck with the title’s performance if at all ray tracing gets implemented!
The FPS has come down significantly since December update so Asobo should rather concentrate on that before even dreaming about more hardware intensive eye candies.

You do realize real-time ray tracing would be a toggleable option in the menu, right? You wouldn’t even see the option if your video card doesn’t support the technology.

So, if you don’t have an nVidia RTX card, your FPS performance won’t all the sudden tank; you won’t even be able to enable ray-tracing. Or, if you have an RTX card and your FPS suffers too much from it, then disable it.

Here’s a screenshot of the ray-tracing options in the game called Control:

Or you can turn it completely off:

And the Minecraft RTX Beta also has a toggle on/off option for ray-tracing, as well.

As to your concern about devs spending time making ray-tracing rather than fixing general FPS issues sans ray-tracing, I hear you. I feel devs are pretty good at multi-tasking, though. I don’t think it’s typical for any game dev to apply 100% of their resources toward one thing. They’re constantly addressing multiple bugs and performance issues at a time, while often also looking at introducing new features or evolutions.

In fact, with real-time ray-tracing being a newer tech, I’d have to believe the set of devs working on it are particularly specialized or trained in it; whereas many of the other devs wouldn’t know a lot about it. That’s just my hunch, though. Either way, I still feel it’s feasible and realistic for the dev to, simultatneously, work on multiple things.

Fixing the FPS in the vanilla game and implementing real-time ray-tracing are not mutually exclusive; and one does not necessarily preclude the other.

===========

If you want to further future-proof the game, though, I really think you’d want ray-tracing. Now would be the time to do it, lest too much time goes on and the game stops getting support from MS/Asobo. Your PC hardware will improve over time. Without MS/Asobo support, the game won’t (aside from cool mods and such using the existing infrastructure, for the most part, of course)

Personally, when it comes to Flight Simulator, I’d rather have an amazing game/sim my PC can barely run today, than a mediocre one today that my more advanced hardware of tomorrow will laugh at. That is because I know my PC hardware will improve over time; the game might not. I know from experience. I tried to re-install and play Flight Sim 2004 and Flight Simulator X five or ten years ago, and I just couldn’t get into it as much as I wanted. The graphics were pretty bad. To be honest, I felt they were pretty bad or non-immersive when they originally came out even – the flat ground with images of trees or houses, or occasional buildings, or areas I knew but the game made them look very generic – just didn’t do it for me. Not immersed enough. It was wishful thinking on my part when I bought them at release.

There’s so much going into this current Flight Simulator, I’d really be surprised if Microsoft made another one within ten years. When you look back 10-15 years from now, I bet you’ll be thankful ray-tracing got implemented in this flight sim (if they implement it). I could be wrong, but I think you would be

Perhaps I meant that there are many more things needing fixes/implementation, case in point being absolutely no mention of low visibility simulation like fog/smoke/haze anywhere in dev roadmap. This along with a replay system should have been there right from day 1.
