Quoting: OdisejDoes Stadia "beam" picture to you computer and computer sends the input to the server? Is that all? It does not matter what OS is being used on the device at home? It can be a 386sx as far as google is concerned? I will be most grateful if somebody explains this.

That's pretty much it! It's like watching a video on YouTube, but it's interactive and let's you send inputs from your controller to Googles server where the game runs. The server encodes a video stream instead of outputting the graphics to a display. The video stream is sent to your client which plays it back just like any video in your browser. For now it's Chrome only. The time it takes between your button press until you see a change on screen is about 150-200ms I think, which is about the same as a console connected to an average TV without "game mode" enabled on the TV, which means it's going to be fine for most people but it will be annoying for latency sensitive people playing fast paced games.

I think that it will be much lower than 150-200ms. I have aprox 80ms round-trip right now over mobile Internet between my home computer in Sweden and one of our servers in the UK. And Google is going to use local servers.

My number is based on DF's test of Project Stream [External Link]. They are measuring not just network latency but total latency from button press to on screen reaction using a 120fps camera. It's possible it has been improved and will be improved further, but it will never be as fast as playing locally on a decent PC of course. I think Stadia will be fine for a lot of games but I wouldn't use it for stuff like Doom or CS:GO, especially since I like to play those sort of games at higher refresh rates than 60hz.

Interesting that the Xbox had 145ms there, Bluetooth in the controller perhaps plays a role there. But the article also shows that we are not talking about an additional 179ms of latency but between 67-100ms since the local PC also showed quite high latency.

This is all strange to me who works with low latency financial data where we constantly keep things well below 1ms, these numbers just look god awful to me :)

Edit: And it surely can get way lower than that, we run one service where we receive financial press releases from various news agencies over HTTP where I've written a very low latency HTTP server to minimize latency. It calculates the latency from the moment of connect to receivment of the last byte+processing and as you can see it's in the microsecond range (this is a log from a Swedish news agency that sends from the Google Compute Cloud to one of our servers in Stockholm and each received file is between 2-3k in size):

Quoting: OdisejA little bit late to the party so sorry for the late question. Is there a soul among us that can explain the technology behind this to me? I mean I am too old to understand some things especially when I think about lag and response of some games in the past. I still remember Duke Nukem 3D played over a modem with a friend and what happened if the modems had to reconnect or the line was too noisy. Or the pings we got with first lan an internet connections. I mean, so many things had to work just right for it to be playable.

The main change from "back then" is that the latency over Internet (if everything works as it should) are orders of magnitude lower than what you could get over a modem.

Regarding how it works, you are 100% correct in your assumption in the second paragraph. They send a compressed picture to you ala Netflix/Youtube and you send the input to them so the performance of your local machine does not really matter.

Quoting: F.UltraYeah, boo on Google for providing a service that people might enjoy and want to pay

Excellent point! That's exactly what I wasn't talking about. It's probably frustrating to have so much to say but to never be able to actually really join any conversations, isn't it?

Quoting: F.Ultra... if happens to be a success it's only because people are not as smart or hip as you.

Obviously. Yes. But don't let it get you down, if you really apply yourself you might get there one day.

Ok, so please explain to stupid little me how exactly "This latest outbreak, Stadia, is just the latest ploy to harvest money and data from its dewy-eyed herd of human ruminants" is "exactly what I wasn't talking about" when I wrote "Yeah, boo on Google for providing a service that people might enjoy and want to pay".

I mean how can what you wrote be interpreted in any other way? Now you might have meant something completely different and I'm willing to give the benefit of a doubt here but you wrote those exact words that I replied to.

Quoting: NanobangGoogle is a plague. This latest outbreak, Stadia, is just the latest ploy to harvest money and data from its dewy-eyed herd of human ruminants.

In spite of the big "Linux" and "Vulkan" logos in the picture, I've no doubt Google is just going to be using these as resources to be exploited and not as members of the Communities that created them. I remember everyone being all atwitter about Android being based on Linux, too.

Unless Stadia is only going to stream Linux games and only ones that use Vulkan, I just don't see how this is going to end up being anything that will benefit the Linux Gaming Community. Admittedly, time will tell.

Still, until we know more, I'm glad Liam is keeping us abreast of the latest news on Google's latest in utero scam.

Yeah, boo on Google for providing a service that people might enjoy and want to pay for and if happens to be a success it's only because people are not as smart or hip as you.

Quoting: SalvatosThey finally did remote play? Awesome. I'll finally be able to run games on computers that don't have a dedicated GPU and without having to download them first when I visit family for a few days. Although I would feel bad leaving my computer on just for that. Maybe that will finally convince me to install Folding@home [External Link] and run it in my absence.

There is always Wake-On-Lan

Quoting: Guest

Quoting: ArehandoroGreat update. Interesting seeing yesterday lots of games that I did not know used Vulkan getting the shaders pre-downloaded (Vampyr, Shenmue I/II for example)

Possibly because DXVK uses Vulkan, not the original game. I assume anyway.

Yep, Vampyr in particular does not use Vulkan natively.

Quoting: F.UltraThe inclusion of DXVK 1.1.1 is kind of a bummer since it requires VK_EXT_host_query_reset without plummeting performance in some games and that is not available in any of the stable versions of Mesa yet.

For me Vampyr just took a nose dive performance wise when Steam updated Proton to 4.2-4 today.

I've decided to stay on mesa-git. For the most part it's been stable and while dxvk/d9vk etc are being developed it works best with them. Maybe when these projects mature and settle down stable will be a good option, but for right now..

Do you compile yourself? I used to be on the Padoka unstable PPA but was burned for far too many times when his scripts released some binaries when others failed which lead to weeks without X on some occasions.

One could have hoped that DXVK would have kept the old code path when it detects that the necessary extension is not found and then remove that code path altogether once it's been in mesa stable for some time but I guess that it was too cumbersome.

Quoting: skinnyrafTo celebrate, I bought Hellblade at 50% only to face a "DX11 level 10 required" error on a supposedly Platinum title...

Strange, I have 8 solid hours from start to finish on 4.2-3. Just tested with 4.2-4 to be sure that didn't break it for me and it still works but due to it being an Unreal4 game it suffers the DXVK 1.1.1 slowdowns since I'm not on mesa-git (with 4.2-3 I have very high framerate and nu stuttering while 4.2-4 was unplayable since it was hit even worse than Vampyr).

I hope you get it to work because it's on hell of an amazing game (headphones are a must!).

Remember that Steam clients allows to select specific Proton versions for each game (at least this will be a solution for game that were working fine). But yeah, would be nice to be able to easily select an specific DXVK for each Proton version.

When Steam installed 4.2-4 it replaced 4.2-3 for me completely.
