Nvidia RTX cards and DCS - ?

[0414 Wee Neal]

Hi

 

I have no technical knowledge of GPU and CPU and programming, but I have a fair knowledge as a flight sim consumer. So from that layman standpoint will the upcoming RTX cards be a useful addition to my flight sim pc, specifically Rift flying. I don't really understand the 'Ray tracing' bit and I suppose its probably not important to know the finer points?

 

I realise its a bit away yet but my pennies must be saved for the purchase!

 

On a related point what would the advice be on whether to upgrade my motherboard set (new cpu and RAM are expensive and it would mean that only one of my children can have new shoes this year!), when / if I upgrade my GPU?

 

Thanks

Ray tracing basically is a new functionality aspect that allows GPU's to calculate light reflections on objects in real time that gives graphics near photo realism, quite literally.

 

This requires games to be specifically to be written for it so expect some time before this tech is widespread. May take years.

 

That being said I also expect the new cards to be faster in today's games. We dont know how much yet. There are alot of conflicting rumors.

[BitMaster]

Raytracing is years ahead from now.

 

 

Just take a break and look back, 2001 T&L was introduced with the very first Nvidia Gforce card, yeah..I saw it at Cebit that year..long ago. It took literally years until T&L got a foot on the ground and it then was also many cards later.

 

 

 

It's a marketing hype that I think will take years until you can enjoy it as intended ( DCS 3.5 or so along with a RTX 1680 Ti 64G HBM3 )

What the two guys above said. Full on RTing - the photo realistic stuff you see in the blending of real life cinema with CGI - takes a a lot of computing power beyond the current state and capability of most gaming systems. I'm more interested as far as the 2080 line of cards is concerned with how much of a performance increase over those of their predecessors.

[hansangb]

For professionals, I'm sure the adoption will be much faster. ED does not support proprietary APIs or technology, so I don't think we'll see this in DCS.

in addition to that, the difference between 1080Ti and 2080Ti is only 768 CUDA cores, which is less than the difference between 1080 and 1080Ti. This probably means the performance jump will be even smaller than 1080=>1080Ti, unless they made some other breakthrough. Advice - patience. We will see the first benchmarks and how it compares to the previous generation and, more importantly, how it is priced. I would wait for the non-reference boards also.

 

And on top of that you need to take your current PSU into account. It may require upgrade.

Architecture differences between a 1080ti and a 2000 series card makes it difficult to compare cores or speeds directly. We simply need benchmarks.

[STe79ITA]

just finished to watch keynotes from nvidia. Raytrace is awesome and btw the new assetto corsa will have it!

Clock speed, arch differences, nvidia charging $$$$ more than the 1080ti, yadda yadda yadda. :doh:

[Pilotasso]

they'll do that as long as AMD cannot offer competition. Vega 20 in 7nm early next might still be another midrange product like the RX580 is today.

[Goa]

Nvidia rtx prices are ridiculous too high for the 2080ti...and the reason they already release it is probably due the fact AMD is going to relase Navi 7nm in 2019 and so nvidia want to get a lot of money from the 2080ti and probably in 2019 they will relase an upgraded 2080ti with more cudacores and ram...

[Pilotasso]

AMD's new cards won't be competing with NVIDIA's at the high end no matter how much clocks they increase from the 7nm process, because it's not a big die GPU and because it's same architecture as previous generation (they are VEGA, and not NAVI) . They are behind at the moment and that won't change until NAVI comes later, an this one we don't even know what it is exactly.

[David OC]

I may need SkateZilla for this one...

 

Would this be a major change to go from what ED uses now, deferred shading etc to utilizing this NEW technology at some point? Would this be more like DCS 3.5 to have RTX and upcoming Vulkan ray tracing API for DCS. Don't get me wrong here, DCS looks great and Vulkan should give us a nice buffer I hope with larger missions or dynamic missions. I'm just interested what steps ED would have to take to utilize this tech in the future with the direction they have gone now.

 

Vulkan ray-tracing video recording of the session or PDF slides.

 

EDIT

Is it worth going there just because "Nvidia thinks we should" and will it make a game / sim all that much better.

Well if everyone is falling for this, the we see in two years the RTX 3080 TI for 2000 dollars. :D

 

 

Gaming for the rich! :D

The only interesting thing I consider is the potential ability to use the RT part of the card to cast radar waves for pure simulation .

The problem is that the persons who don't invest in Nv RTX card will not benefits the enhancements, which would be unacceptable as the radar is a critical part of the Sim, and not a cosmetic one...

 

So it's urgent to wait...

NVIDIA has released a benchmark slides on 2080 vs 1080.

https://videocardz.com/newz/nvidia-publishes-geforce-rtx-2080-vs-geforce-gtx-1080-comparison#disqus_thread

 

In general around 1.5x higher frame rate and up to 2 times with DLSS mode enabled. Pretty good leap especially with DLSS.

[joca133]

A used 1080 ti can be found for $450 as of today. Im curious about the next couple weeks and the 2070 vs 1080 ti to be honest.

What about: a new 1080ti for around €800 vs a new 2080 for €800

 

Wonder which one comes out best from "honest" independent benchmarks, as I'm planning on buying either one of them.

Is it even possible?I mean, radar waves are not light , I dont know if you can "generate" a ray "physics" and using it as a game logic.

As much as I've understood about RT is that developers can now adding lights like IRL and expect realistic outcome in real time, nothing more than that..

[tobaschi]

raytracing will stay an bad-optimized unicorn as long consoles does not support it.

 

For DCS i think there are other engine priorities, which would help the majority of simmers and not only 5% with a pseudo raytracing card.

 

Beside of that:

AMD is basically dead in the PC graphics card market. Steam survey shows them at 14% :cry:

[nrosko]

The lighting in DCS is by far the worst thing about the game, aliased shadows in cockpit, light sources that simply look like semi transparent textures, reflections on the cockpit look like somebody drew on it with a feltip & the ground lit up by street lamps again looks like its painted on the textures. It's a stark contrast to what is otherwise a very pretty game. I hope they find a way to incorporate these features one day, at least the DLSS that could give a large fps boost.

If you have @26 minutes to spare, AdoredTV has a great video on what you can expect for performance from the RTX in the absence of real benchmarks. He literally does the math based on the published specs, and shows where NVidia is using smoke and mirrors in their marketing.

 

NVidia has the full marketing/hype train in force, but they are focusing on anything but raw performance vs the GTX cards, and that should be a red flag to everyone.

 

 

The bottom line is that unless they are hiding something (other than the truth), we won't see gains much higher than 25-35% at best.

25-35% is actually a big gain.
