Microsoft ayaa ku dhawaaqday nooca xiga ee DirectX oo loo yaqaan DirectX 12 Ultimate . Maxaa ka dhigaya ku dhawaaqistaan ​​mid xiisa leh ayaa ah in tani ay sidoo kale iswaafajiso labadaba PC iyo Xbox Series X ie , garaafyada midaysan ee PC iyo Xbox Series X. Nooca hore, DirectX 12 , hadda waa ku dhawaad ​​lix sano jir, iyo casriyeyn la taaban karo ayaa sabab u ahaa, inta badan sababtoo ah ciyaaraha Xbox ayaa sidoo kale diyaar u ah PC. Microsoft ayaa dhawaan ku dhawaaqday faahfaahinta Xbox Series X , oo ay ku shaqeyso DirectX 12 Ultimate . Aynu eegno dhammaan sifooyinka iyo agabka horumariyaha ee Microsoft ay bixiso.

Tilmaamaha ugu dambeeya ee DirectX 12

Kahor intaanan bilaabin, Microsoft waxay si cad u sheegtay in haddii aad iibsato PC cusub oo sita astaanta DX12 Ultimate , waxaa dammaanad qaadaya inay taageerto dhammaan astaamaha qalabka garaafyada jiilka xiga. Waxaa ka mid ah

1. DirectX Raytracing 1.1
2. Hooska Heerarka Isbeddelka ah
3. Mesh Shaders
4. Jawaab-celinta Muunalaha

Dhammaan sifooyinkaan waxay hubin doonaan in kombuyuutarku awood u yeelan doono inuu ciyaaro ciyaaraha jiilka xiga ee ku xiran tan. DX12 kama dambaysta ah waxay ku shaqayn doontaa qalabka jiilka hadda jira, laakiin ma keeni doonto faa'iidooyinka muuqaalka ee sifooyinka cusub. Midaynta goobuhu waxay kordhin doontaa korsashada, waxayna ku dhiirigelinaysaa horumariyeyaasha inay u sameeyaan ciyaaraha labada goobood.

1] DirectX Raytracing 1.1

Waxay siin doontaa horumariyeyaasha fursad ay ku gaaraan heer garaafyo, taas oo suurtagal ahayd oo keliya Bollywood . DirectX Raytracing ama DXR waxay suurtogal ka dhigtaa in la raadiyo waddooyinka iftiinka xisaabinta fiisigiska-nolosha ee runta ah. Waxa kale oo ay u fududaynaysaa matoorada ciyaarta in ay soo bandhigaan walxaha marka ciyaartoygu uu wareego. Waxaasoo dhan waa suurtagal sababtoo ah GPU -gu wuxuu si toos ah ugu yeeri karaa raytracing isagoon sugin CPU -ga , taasoo u oggolaanaysa inay isla markiiba dhaliso. Waxa kale oo ay bixisaa koofiyadda raytracing Inline - ka kaas oo siinaya horumariyeyaasha ikhtiyaarka ah in ay kaxeeyaan wax badan oo ka mid ah habka raytracing. Waxaas oo dhan heerka hardware.

2] Hoosaynta Heerarka Isbeddelka ah

Soo-saarayaashu hadda si door ah ayey u kala duwanaan karaan heerka hadhka ciyaarta. Waxay u isticmaali karaan GPU -da inay u adeegsadaan faraskooda si ay u helaan muuqaal wanaagsan ama xawaare wanaagsan. Markaa haddii ay ficilkeeda degdega ah ku socoto goobta, devs waxay ku bari kartaa GPU -ga inuu isticmaalo xawaaraha, iyo waayo-aragnimada shaleemada, waydii inuu ka shaqeeyo muuqaallo wanaagsan. Natiijadu guud ahaan waa heerarka qaab-dhismeedka oo kordhay .

3] Mesh Shaders

Habkani waxa uu siinayaa ciyaartoyda awood programmability dheeraad ah. Waxay hadda dhisi karaan adduunyo faahfaahsan oo firfircoon iyadoo ay ugu wacan tahay helitaanka awoodda buuxda ee xisaabinta GPU -ga guud ee dhuumaha joomatari. ^(GPU)Halkii hal shaqo oo hadh ah laga heli lahaa, shaders-ku waxay ka shaqeeyaan guud ahaan kooxda dunta xisaabeed oo dhan.

Rather than a single function that shades one vertex or one primitive, mesh shaders operate across an entire compute thread group, with access to group shared memory and advanced compute features such as cross-lane wave intrinsics that provide even more fine-grained control over actual hardware execution

4] Jawaab-celinta Sampler

Waxay u sahlaysa horumariyayaashu inay ku shubaan textures marka loo baahdo. Markaa marka kamaraduhu ay si degdeg ah u dhex maraan muuqaalka, walxaha qaarkood waxay u muuqdaan kuwo aan boos lahayn. Jawaab-celinta muunaduhu^(Sampler) waxay hubin doontaa inay bixiso tayada muuqaal wanaagsan, waqti gaaban oo xamuul ah, iyo dhidid-xumo yar.

Kaarkee garaafyada ayaa isticmaali doona DirectX 12 Ultimate ?

NVIDIA waxay si rasmi ah ula wadaagtay in taxanaha GeForce RTX   uu noqon doono kan ugu horreeya ee tan la kulmo.

AMD RDNA 2 sidoo kale waa diyaar^{(also ready)} , kaas oo ah AMD qaab dhismeedka ciyaaraha soo socda.

Qalabka iyo Shuruudaha^{(Requirement)} loogu talagalay DirectX 12 Ultimate

Microsoft waxay la wadaagtay tafaasiisha dhamaystiran^{(complete details)} ee qalabka, iyo shuruudaha ugu yar ee lagu horumarinayo iyadoo la isticmaalayo DirectX 12 Ultimate . Waxaa ka mid ah OS, Visual Studio , Windows Insider Preview SDK , Darawalada^(Drivers) iyo qalabka, PIX ( DirectX 12 debugger), iyo in ka badan.

DirectX 12 Ultimate Features, Tools and Minimum requirements

Microsoft has announced the next version of DіreсtX dubbed DirectX 12 Ultimate. What makes this announcement interesting is that this also aligns both PC and Xbox Series X i.e., unified graphics platform across PC and Xbox Series X. The earlier version, DirectX 12, is almost six years old now, and a significant update was due, mainly because games on Xbox are also available for PC. Microsoft recently announced Xbox Series X details, which are powered by DirectX 12 Ultimate. Let’s take a look at all the features and developer tools Microsoft is offering.

DirectX 12 Ultimate Features

Before we start, Microsoft has clearly stated that if you buy a new PC that carries the logo of DX12 Ultimate, it is guaranteed to support all next-generation graphics hardware features. It includes

1. DirectX Raytracing 1.1
2. Variable Rate Shading
3. Mesh Shaders
4. Sampler Feedback

All these features will ensure that your computer will be able to play next-generation games that depend on this. DX12 ultimate will run on the hardware of the current generation, but it will not deliver the visual benefits of the new features. The unification of the platforms will increase adoption, and inspire developers to make games for both the platforms.

1] DirectX Raytracing 1.1

It will give developers a chance to achieve a level of graphics, which was only possible in Bollywood. DirectX Raytracing or DXR makes it possible to traces paths of light with true-to-life physics calculations. It also makes it easy for game engines to render objects as the player moves around.  All this is possible because the GPU can directly invoke raytracing without waiting for the CPU, allowing it to spawn immediately. It also offers an Inline raytracing hat that gives developers the option to drive more of the raytracing process. All this on the hardware level.

2] Variable Rate Shading

Developers can now electively vary a game’s shading rate. They can use the GPU to use its horsepower either for better visuals or better speed. So if its fast action paced scene, devs could instruct the GPU to use speed, and for a cinematic experience, ask it works on better visuals. The overall result is increased frame rates.

3] Mesh Shaders

This feature offers gamers more programmability power. They can now build more detailed and dynamic worlds thanks to the availability of full power of generalized GPU compute to the geometry pipeline. Instead of a single function of shade, esh shaders operate across an entire compute thread group.

Rather than a single function that shades one vertex or one primitive, mesh shaders operate across an entire compute thread group, with access to group shared memory and advanced compute features such as cross-lane wave intrinsics that provide even more fine-grained control over actual hardware execution

4] Sampler Feedback

It enables developers to load in textures when needed. So when the camera movies swiftly through the scenes, some objects look out of position. Sampler feedback will make sure to offer better visual quality, shorter load time, and less stuttering.

Which graphics card will get to use the DirectX 12 Ultimate?

NVIDIA has officially shared that the GeForce RTX  series will be the first to experience this.

AMD RDNA 2  is also ready, which is AMD’s upcoming gaming architecture.

Tools and Requirement for DirectX 12 Ultimate

Microsoft has shared complete details of the tools, and the minimum requirements to develop using DirectX 12 Ultimate. It includes OS, Visual Studio, Windows Insider Preview SDK, Drivers and hardware, PIX (DirectX 12 debugger), and more.
