PPSSPP, the open source PSP emulator has a major new version, will use Vulkan in future
23 Feb 2016 at 8:04 am UTC
Quoting: Beamboom... But how are the psp disks read? Or is this just to run pirated stuff?
Like all emulators, it's for running the roms you dump from your legally bought discs. Although as long as you've bought the game, in most sane legal systems it's fine to use a rom dumped by someone else.

EDIT: Substitute relevant media and data format for discs and roms where applicable.
Looks like Dota 2 with Vulkan isn't too far away

Quoting: AkonadyBut the game will have a option for use OpenGL or Vulkan? Or the game (DotA in this case) will substitute by itself?
That depends entirely on how the game's developer wants to do it. But I'd bet Dota will let you select the backend if it's released any time soon. We'll just have to wait and see.

Quoting: AkonadyWell, when released, how can I use it?
I mean, I need download a specific driver/program?
I will need uninstall OpenGL and install Vulkan?
I will need wait the developers of my distro release a update with the Vulkan?

How it's gonna be?

I have GTX 970 and i5 4460.
You'll need to install a driver with Vulkan support for your GPU and a game that makes use of the API. That's all.

Quoting: GuestWhich intel cpus are the minimum to use Vulkan? Is Ivybridge enough?
Quoting: Intel's Vulkan driver announcementThe driver currently supports Sky Lake all the way back to Ivy Bridge. The driver is Vulkan 1.0 conformant for 64-bit builds on Sky Lake, Broadwell, and Braswell. We are still having a couple of 32-bit issues and support for Haswell, Ivy Bridge, and Bay Trail should be considered experimental.

Quoting: TheBossCroteam clearly stated they aren't doing any multithreading in Vulkan at the moment, which would be a reason why Talos with Vulkan is slow.
My point was that their code might not be the only reason. Vulkan drivers are tiny, but as your Intel quote made clear there's still room for optimization. And as SketchStick pointed out, the shader compiler's also fresh off the assembly line and might see a lot of improvement in the near future. In fact we've got a ton of reasons to expect that the infrastructure around Vulkan is pretty high on everyone's to-do lists and we will see the drivers and tools mature at a good pace. I'm sure AMD will catch up as well, as soon as they get the whole AMDGPU transition out of the way.
How SteamOS could become a better console competitor

Quoting: eddie-fossIMO, SteamOS needs a standardized and organized SDK like XBoxes, Playstations, Nintendos SDKs;
I'm not sure I agree. Sure, locking it all down and forcing developers to adhere to strict development guidelines and unified tooling would make it all a tighter, more console-like experience. But what is even more important for the success of SteamOS than pleasing users is convincing game developers to jump in. The success of Windows is mostly due to software companies adopting the OS as their platform of choice back in the day. Sure, it wasn't a bad OS compared to the competition at the time either, but as we all know, this hasn't been true for a while now.

Building walls around the "garden" would also go against many of the reasons Steam is such an attractive platform for developers. A great console OS won't do much if developers have no incentive to get their games on it. Valve's idea seems to be to minimize the actual effort of developing and maintaining SteamOS ports for Windows games, so that there's little reason not to. Every cross-platform API (like Vulkan) is a step closer to this goal. And I'd say this strategy seems to be bearing fruit so far. Not quickly enough for many of you, but personally I'm quite optimistic. Even if SteamOS never takes off, I doubt Steam on Linux is going to disappear any time soon.

Quoting: TheBossRemember though, it probably won't perform as well as OpenGL when it's first released much like The Talos Principle beta.
This also highlights the fact that although Croteam's code might be slow right now, Nvidia's Vulkan driver is unlikely to be well optimized at this point either. I guess it's pretty hard to optimize a driver until there are real world apps/games using the API to test with. Isolated, synthetic tests are unlikely to reflect real world use cases. I'm sure all the big IHV's will get there eventually, and relatively quickly due to Vulkan's design.

Quoting: AnxiousInfusion20:43 yikes I'm not seeing Crytek on that list.
Yeah, it's not an exhaustive list of all game engine developers to use Vulkan in the future. The ones that are in the list are all Vulkan Working Group participants, as can be seen at ~2:50. No Crytek there either. But that's okay. They got more than half a slide for themselves at 29:00.

EDIT: Crytek isn't Croteam... :whistle:
How SteamOS could become a better console competitor
21 Feb 2016 at 8:46 am UTC
Quoting: eddie-fossIf you do checksum for all files with same name you will see many duplicated and actually most of the games has a folder with their needed dependencies which some of them is redundant.
In my years of linux I learned that symlinks is a very eficient tool to avoid the flaw of unpatched cloned files.
Ah, that's true. Games often ship their own dependencies. This isn't something valve can "fix", unless they forcibly take over the actual packaging for developers. Now they simply provide the tools and the platform. The Steam Runtime is provided as a "standard library" of sorts, but there's no requirement that games actually make use of it. Not much of an issue in my opinion, and definitely not unique to SteamOS.

Quoting: eddie-fossPS.: SteamOS is a mess compared with any distro, there is no consistent game/software packaging like we have in all linux distros, there is no dependencies check and there is no file duplication check.
What exactly do you mean? Steam handles the installation of games and their dependencies (the Steam Runtime) and behind the scenes SteamOS--being a Debian derivative--uses APT for package management to cater for the rest of the system.

But SteamOS is obviously not supposed to compete with all-rounders like Ubuntu, Fedora, Arch and the like. It's just a purpose-built vehicle for Steam. If that's not what you want, go ahead and run Steam on another, supported distribution like Ubuntu. Obviously you're not part of the target audience for SteamOS. Neither am I, so don't take this the wrong way.
