[336.00 --> 337.00] X for extreme. |
[337.00 --> 340.00] X for that X factor. |
[340.00 --> 341.00] X for... |
[341.00 --> 342.00] Cross. |
[342.00 --> 343.00] Fire. |
[343.00 --> 344.00] Again. |
[344.00 --> 345.00] More crosses. |
[346.00 --> 347.00] You don't like this? |
[347.00 --> 348.00] You know what? |
[348.00 --> 349.00] Try this one. |
[349.00 --> 350.00] You know what? |
[350.00 --> 354.00] I don't even, I don't even, I don't even need, I don't even need all the comments about how I should get rid of you and bring back Luke. |
[354.00 --> 356.00] I wanna get, look, trust me. |
[356.00 --> 358.00] Look, we all want Luke to be here. |
[358.00 --> 359.00] We all want Luke to be here. |
[359.00 --> 361.00] Okay, James more than anyone. |
[361.00 --> 366.00] Because he gets to be in the same building as Luke when Luke is here doing the show. |
[366.00 --> 367.00] Ah! |
[367.00 --> 368.00] Um, but... |
[368.00 --> 370.00] Hey, one in twenty of those comments say I'm okay. |
[370.00 --> 371.00] Ha ha. |
[371.00 --> 372.00] Thank you. |
[372.00 --> 373.00] And there's still a chance. |
[373.00 --> 382.00] And if my doctor got five percent on his exam, well, gee, I wouldn't be here to tell you about what if my doctor got five percent on his exam. |
[382.00 --> 384.00] Discount Luke. |
[384.00 --> 385.00] Discount Luke. |
[385.00 --> 386.00] Yvonne's pregnant again. |
[386.00 --> 388.00] Um, okay, so... |
[388.00 --> 390.00] Wow, that would be complicated. |
[390.00 --> 395.00] Um, okay, so basically they've branded a bunch of different things a bunch of different ways. |
[395.00 --> 410.00] Crossfire has even been used to describe running a craptastic AMD add-in card with the onboard graphics on your motherboard to make it slightly less craptastic. |
[410.00 --> 412.00] And it never made any sense. |
[412.00 --> 414.00] It was always stupid. |
[414.00 --> 417.00] That's not to say that all Crossfire was always stupid. |
[417.00 --> 419.00] That particular one was always stupid. |
[419.00 --> 422.00] But this branding has always been really confusing. |
[422.00 --> 426.00] So, now, they're getting rid of the Crossfire brand. |
[426.00 --> 433.00] And if you want my honest opinion, I think it's just because they don't want to take responsibility for it when it just doesn't work. |
[433.00 --> 435.00] But what does it have to do with APIs? |
[435.00 --> 448.00] Okay, so what it has to do with APIs is that DirectX 12 and Vulkan are going to support multi-GPU rendering in a different way than previous APIs. |
[448.00 --> 458.00] So, with DirectX 9 to 11, the way that SLI and Crossfire worked was via proprietary means enabled through the graphics card manufacturer. |
[458.00 --> 467.00] So, the game engine did have to support it, but it didn't actually have to be explicitly coded in by the game developer. |
[467.00 --> 469.00] So, you could actually take a game. |
[469.00 --> 472.00] Let's say it used the Unreal Engine, for example. |
[472.00 --> 477.00] You could take some random game by some indie developer using the Unreal Engine. |
[477.00 --> 483.00] And even if you had two cards and you got no performance benefit from SLI or Crossfire whatsoever. |
[483.00 --> 484.00] No scaling. |
[484.00 --> 485.00] No scaling at all. |
[485.00 --> 498.00] What you could do is a lot of the time, you could go into your Nvidia control panel, you could manually enable some form of multi-GPU rendering, be it alternate frame rendering or... |
[498.00 --> 500.00] I mean, that's the most common one. |
[500.00 --> 507.00] And you could apply a profile from a similar game, also using the Unreal Engine, and boom. |
[507.00 --> 511.00] You would have SLI or Crossfire scaling and a lot of the time it would actually work. |
[511.00 --> 512.00] Okay. |
[512.00 --> 513.00] To the extent that it worked. |
[513.00 --> 519.00] When it comes to DirectX 12, that's just not a thing. |
[519.00 --> 526.00] So, the way that it's meant to be implemented with DirectX 12 in particular is by the game developer. |
[526.00 --> 532.00] So, they are supposed to actually code into the game how it would utilize multiple GPUs. |
[532.00 --> 538.00] In theory, this would actually give you the flexibility to mix and match graphics cards. |
[538.00 --> 554.00] In practice, I personally think that this is basically the end of multi-GPU outside of a very small number of niche games where the developer bothers to code it in. |
[554.00 --> 555.00] Because even... |
[555.00 --> 557.00] That's how it is right now. |
[557.00 --> 558.00] There's only... |
[558.00 --> 560.00] Ashes of Singularity, Tomb Raider... |
[560.00 --> 561.00] There's only a handful. |
[561.00 --> 564.00] Does Tomb Raider even scale well with MGPU? |
[564.00 --> 565.00] I don't even know. |
[565.00 --> 567.00] Well, it does better on DirectX 12 than 11. |
[567.00 --> 568.00] Okay. |
[568.00 --> 569.00] Well... |
[569.00 --> 571.00] There's only a few that do that. |
[571.00 --> 578.00] So, pretty much there will be those games that are as much benchmarks as they are games. |
[578.00 --> 587.00] Where they actually put all of this support into it because what they're trying to do is get, like, tech publications to use their game as a benchmark. |
[587.00 --> 590.00] Which is basically free advertising for the game. |
[590.00 --> 603.00] So, as far as I can tell, a lot of game developers have finally clued in to the idea that putting a baked-in benchmark in the game is pretty much getting marketing for a small investment in development time. |
[603.00 --> 605.00] Not to mention that it's just convenient for the user. |
[605.00 --> 606.00] No kidding. |
[606.00 --> 609.00] Like, Doom is the only new-ish game that we're featuring at all. |
[609.00 --> 612.00] In all of our videos, we're still showing Deus Ex in 2014. |
[612.00 --> 613.00] Yep. |
[613.00 --> 616.00] So, basically, that's what I think. |
[616.00 --> 623.00] I think AMD is changing the branding because they just don't want to be associated with it not working. |
[623.00 --> 626.00] But is MGPU really even new branding? |
[626.00 --> 627.00] Or multi-GPU? |
[627.00 --> 631.00] It seems just more like the name for it. |
[631.00 --> 633.00] Well, that's exactly it. |
[633.00 --> 636.00] They're almost de-branding it. |
[636.00 --> 640.00] Speaking of de-brand, this episode is brought to you by... |
[640.00 --> 642.00] No, actually, it's not. |
[642.00 --> 652.00] So, it's almost like they're just removing all their branding from it so that they have to take no responsibility whatsoever when the experience sucks because game developers don't bother. |
[652.00 --> 654.00] Because even now, with the relatively... |
[654.00 --> 659.00] And to be clear, I'm not saying that it's not a lot of work to make a game or whatever. |
[659.00 --> 669.00] Even with the relatively small amount of work that a developer has to put in in order to have SLI or Crossfire work properly, a lot of games, it's really broken. |
[669.00 --> 674.00] So, asking them to go several steps further and code it right into the game? |
[674.00 --> 676.00] Yeah, we'll see. |
[676.00 --> 679.00] I think you're right. It's just gonna be over. |
[679.00 --> 681.00] If everyone's not doing it, there's no... |
[681.00 --> 683.00] When would you ever make that investment? |
[683.00 --> 686.00] Since it's the same cost as upgrading your card. |
[686.00 --> 688.00] You need me for two minutes? |
[688.00 --> 689.00] Yeah. |
