Commissar SFLUFAN Posted March 20, 2020 Share Posted March 20, 2020 DirectX 12 Ultimate brings Xbox Series X features to PC gaming Quote Today, Microsoft is announcing a new version of its gaming and multimedia API platform, DirectX. The new version, DirectX 12 Ultimate, largely unifies Windows PCs with the upcoming Xbox Series X platform, offering the platform's new precision rendering features to Windows gamers with supporting video cards.

jaethos Posted March 20, 2020 Share Posted March 20, 2020 Variable rate shading and sampler feedback look like they could do wonders for performance if devs make good use of them. The sampler feedback in particular is supposed to allow the Series X to behave as though it has more than 16GB of RAM, according to MS. Since EVGA replaced my 1080ti with an RTX 2080 I'm ready to go for these things on my PC. Quote Link to comment Share on other sites More sharing options...

That's a good upgrade because Nvidia stopped optimizing 1000 drivers a long time ago! And you get better RTX performance. Quote Link to comment Share on other sites More sharing options...

As that article elaborates, next gen we should be expecting those types of performance gains from upscaling techniques, not VRS. It’s a welcome addition, but it’s not a magic bullet. Fortunately, devs can use both. Quote Link to comment Share on other sites More sharing options...

TwinIon Posted March 21, 2020 Share Posted March 21, 2020 The video in the OP says that VRS can improve performance "up to 15%" in Wolfenstein. 15% is a huge number. It's roughly the difference between a 2080 Super and a 2080 Ti. That DF analysis showed 7% with RT off and 4% with RT on. I would suspect that, given the nature of the tech, some games will benefit from it far more than others. A ~5% increase in performance is nothing to sneeze at, and if it can partially or entirely offset the additional load required by RT, that's a pretty tangible benefit.

A ~5% increase in performance is nothing to sneeze at, and if it can partially or entirely offset the additional load required by RT, that's a pretty tangible benefit. We already know RT is much more than a ~5% hit, even at lower settings and less comprehensive uses. Every little bit matters, yes, especially with RT. But conservative applications, resolution drops, upscaling techniques, even 30fps caps in some cases, are going to be the key to offset the performance hit at large.

AbsolutSurgen Posted March 22, 2020 Share Posted March 22, 2020 Everything I have read suggests that VRS degrades the IQ, where the user "is paying less attention". I assume that the amount of degradation, and the area of the screen impacted are selectable by the dev. So the % improvement should change by game. If you're getting a 50% improvement, there has to be a significant hit to IQ on a significant part of the screen. Or am I missing something.

TomCat Posted March 23, 2020 Share Posted March 23, 2020 oh my Whats this the X performing better then a 2080ti say it aint so MS has also developed a new compression technique for textures Called BCPack that reduces the size of 4k textures by 50% plus.

Not understanding very technical details of something you haven't been trained for does not make you stupid. I really would like to understand more of it -- can you help me: 1) What is an Input Assembler? How does it work? 2) What is a Primitive Assembler? How does it work? 3) What is SV_Cullprimitive? 4) What is attribute shading? 5) What do you think is the best culling method? 11 hours ago, TomCat said: xbox performed better at 4k then the 2080ti at 1440p when culling images. How did you get that conclusion? I didn't see a comparison where the 2080Ti was run through a mesh shader when rendering the dragon (I only saw a number with the vertex shader). I don't really think the presenter ever intended to do a comparison between 2080Ti vs. SeX. Quote Link to comment Share on other sites More sharing options...

chakoo Posted March 25, 2020 Share Posted March 25, 2020 https://www.youtube.com/watch?v=CFXKTXtil34 That's a pretty interesting video discussing how they've cleaned up the pipeline. It's quite nice.

You keep talking about things and making extrapolations about things you've shown you don't have an understanding of for simply fanboyish reasons. I'm telling you this as both a former game developer and graphics pipeline programmer. Just cut it out and you'll get called out less. On 3/24/2020 at 10:33 AM, AbsolutSurgen said: 5) What do you think is the best culling method? It's not really an either/or scenario. It's about reducing the workload being sent through the GPU on things you don't see. The standard culling method mention in the video is something you still would do to save on stuff being sent off to the GPU for transformation and processing. This video is on processes you can do while in the geometry stage to cull further before it's sent off further down the pipeline to later stages (tessellation/fragment/rop).
