Digital Foundry Article Technical Discussion [2021]

Yeah, good GI would be a lot better, but unfortunately just like any new technology there tends to be one thing that most developers focus heavily on because then it's really easy to say, "LOOK, Here's the new shiny tech in our game!" And for current RT, this unfortunately is reflections. That's why I was so happy when Metro: Exodus Enhanced edition instead focused on the lighting with reflections being left off on the consoles when they needed more rendering budget.

The character looks like it has an ambient value or other phantom light source applied which is not being accounted for in the RT reflections.

 

Nice interview @Dictator

 

D3D12 on PC is different from XBox code, how?

Ray tracing using DirectX requires D3D12?

 

One of the things I found interesting was that the GDK doesn't report back if the display is VRR.
Be interesting when DF do their VRR analysis on this.
I know the 1X didn't hassle LFC very well, so this will tell us if it's improved and if it can be relied on.

 

That memory reduction... hard to tell if it's "competence" from the people who made these optimizations of "incompetence" from Microsoft team for needing so much memory at launch.

 

"glass cockpit" is full blown web browser with html, css, javascript etc .... excuse my language but what the actual fuck!?

 

The game is a huge undertaking, so you optimize what you can when you can.

Was interesting to hear this, but given just how it can be modded not a bad decision.
Wonder if its using general commonly available libraries to handle it etc.

It was also not a new game totally from the ground up. So it's very possible there's still some performance to come.

 

Not the first I've heard of using html for markup and 2D UI elements. PubG comes to mind? Probably a whole bunch of 'em that you never know about unless an error occurs, especially if it's actually pulling assets online via regular http and it gets tripped up by network shenanigans (firewall/proxy/dns.)

from some quick googling, a GDC talk: https://www.gdcvault.com/play/1022054/How-to-Implement-AAA-Game
the talk's slides: https://www.gdcvault.com/play/mediaProxy.php?sid=1022055

 

If I have understand correctly the overuse of memory was because the game had multiple datasets for each info panel and now they have just one world data set for all panels.

 

some people have the instrument displays mirrored in separate lcd's installed in a cockpit

 

I was going to say imgui would probably be of huge benefit to this title, but you might lose the flexibility to do cool modding like that.

 

Not that unusual

In fact I would say a lot of games use something similar but simplified, maybe not a whole browser but a markup language (I could prolly dig up some of my stuff from >10 years ago you'ld look at it and go hey thats very much like html)

 

FlightSim games have to take into consideration the custom rigs their higher end userbase has to play them. You're effectively dead in that world if you can't cater to the hardware and peripherals they use. Similar to sim racing titles.

 

Usual really good episode with shout out to @iroboto

 

Nice! Sorry been away for a while. So busy trying to get my cuda environment working with opencv so we can get some speed going!
And a busy month, last minute cottages before my girls go back to school and all three have birthdays this month separated with 2 weeks apart into sept.

 

Or Vulkan...

Flight Simulator isn't made by a MS Studio. It's made by the independent studio, Asobo Studio. I'd say it's fairly impressive what they accomplished as an independent studio that isn't owned by any major publisher.

Currently the perfomance state of Halo Infinite is currently objectively bad on XSX in the 120hz mode. Sure on paper 1440p 120hz looks good but it's only the case in specific conditions. According to VGTech, when played in normal conditions (so combat, I mean it's a FPS), the game mostly runs at 1080p at 100-110fps. And it only hits 120hz when looking at the sky or a wall.

It's not like the game is a looker, too. And from what I saw the maps are rather small. Compared to Warzone (120hz) and its way bigger and better looking maps, this looks technically mediocre IMO.
