Wps105 m - new gpu features of nvidia's maxwell architecture (present…

به صورت خلاصه :
pdf درباره معماری مسکول 1 و 2 انویدیا و قابلیتهای سخت افزاری جدیدی هست که با استفاده از DX12 سازنده ها میتونن از اونها استفاده کنن بعضی قابلیتهای روی کارتهای DX11 به کندی قابل اجرا هستن و روی DX12 با استفاده از سخت افزار جدید بهتر اجرا میشن بعضی قابلیتها هم برای پیاده سازی احتیاج به سخت افزار کاملا جدید دارن و روی کارتهای DX11 اجرا نمیشن.
داخل pdf تکنیک جدید AGAA 2A هم معرفی شده که به ادعای انویدیا تاثیری مثل MSAA 32X داره ولی به واسطه قابلیتهای جدید با Performance خیلی کمتر این تکنیک برای اجرا به کارتهای GTX 960/970/980/TitanX احتیاج داره.

فعلا فقط نسخه چینی این pdf اومده ، ترجمه pdf از چینی به انگلیسی با گوگل ترنسلیت:

3. On the existing 28-nm node with a new architecture to improve performance significantly improve the energy consumption ratio is designed to provide the best support for DirectX 12 is designed to focus on the new graphics features provide real-time global illumination in complex dynamic scenes ( GI) effects provide a higher quality of working set memory interface programmable anti-aliasing (AA) (working set) management scalable 2D graphics acceleration capabilities of the DirectX 12 hardware platform to provide the best target architecture NVIDIA Maxwell


4. NVIDIA Maxwell architecture target hardware features DirectX12 new conservative boundary rasterization (Conservative Rasterization) ordered raster view (Raster Ordered Views) splicing resources (Tiled Resources) Maxwell support other new features of the new special effects technology outlook presentations Summary


5. Direct3D 12 API latest high-performance graphics hardware closer to the bottom, more direct hardware access can run on Microsoft supports a variety of hardware platforms are supported by a variety of excellent development tools provide support for all major hardware vendors

7. conventional rasterization if the pixel is not the center of the triangle cover, no output conservative rasterization border: output all pixels of the triangle touch Application examples: raytracing shadow of voxels (Voxelization) second generation support this feature Maxwell GPU GTX 960/970/980 / Titan X DX12 conservative rasterization border


8. no ROV: output pixel shader is disordered ROV can guarantee a specific order pixel shader output can be used to solve many problems: programmable mixing operations efficient, flexible and transparent picture sequence-independent (OIT) transparent deferred rendering algorithm: Any Package g-buffer data in the second-generation Maxwell GPU support this feature orderly output performance loss will bring depth complexity will affect the performance DX12 orderly raster view (ROVs)


9. stitching 2D & 3D maps and virtual memory array by sea way to store massive amounts of data and use resources DX12 DX11.2 provide 2D stitching adds 3D mosaic texture streaming application resources (texture streaming) / shear mapping (Clipmaps) adaptive shadow Mapping (adaptive shadow map) sparse multi-resolution rendering (Sparse multi-resolution rendering) sparse voxel grid (Sparse voxel grids) second-generation Maxwell GPU support this feature depends on the specific application performance DX12 stitching resources

17. Minimum hardware requirements: D3D feature level 11 Recommended: D3D feature level 12 (conservative boundary rasterization can significantly improve the speed) which games will use raytracing shadows: the shadow of the game requires a lot of clarity in the game may be classified as "high" or "very high" level of screen effect has been integrated into the Unreal 4 engine raytracing shadows - Hardware considerations


18. The fluid simulation often requires a lot of data previously restricted to splice 3D algorithms limited memory resource properties using DX12 containing only sparse fluid simulation and computational fluid storage grid to save memory space, reduce the computation time

31. How to control the response time of 20 milliseconds required hardware and driver provided "Timewarp" GPU technology before each output image to the display, immediately conduct a picture adjustments for the current helmet VR Direct location:? Timewarp


32. Timewarp technology can be a delay of 20 milliseconds or less effective in approaching the frame rate of less than 60 for the game is also effective support Timewarp technology NVIDIA GPU:! Section 500 and 600 series GPU, all 700 and 900 series GPU will be the future of GPU have better support VR Direct: Timewarp

اصلا تاحالا باز داشتیم که آپشن 32x داشته باشه؟:-/ اصلا بالاتر 8x رو نمیتونم تصور کنم :d
 
نوشته شده توسط A-L-I:
تمام قابلیت های DX12 روی سری 9 انویدیا کامل و بدون مشکل فعال هستند ؟
بیشتر...

هنوز یه سری چیزا دقیق معلوم نیست دلیل اینکه مایکرو یا بقیه خیلی واضح در این باره صحبت نمیکنن نمیدونم چی هست !! ولی تا جایی که من متوجه شدم کارتهای سری 9 انویدیا همه فیچرهای اجباری DX12 و DX 12.1 رو دارن ولی بعضی فیچرهای اختیاری رو ندارن با قابلیت Resource binding tire 3 هم سازگاری ندارن. البته اطلاعات من کامل نیست هنوزم فرصت نکردم کامل برم دنبالش اگر کسی اطلاعات بیشتری داره بگه.

احتمالا اولین کارتی از AMD که FLـهای DX12/12.1 داره R9 390X هست که چند وقت دیگه معرفی میشه.

نرم افزاری یعنی چی؟
به فرض اگه بازی بر اساس دایکرس 12 ساخته بشه من میتونم اجرا کنم یا نه؟

میشه. نهایتا یه سری از آپشن ها رو نمیتونی استفاده کنی. البته خدا رو چه دیدی، شاید Crysis 5 اومد گفت فلان آپشن اجباریه ما باید بمونیم تو کف:p
 
فیل اسپنسر گفته بازیهای dx12 اواخر امسال وارد بازار میشن
Phil Spencer Says First DirectX 12 Games Available by End of 2015 | eTeknix

AMD هم دوباره تاکید کرده تا همین الان استفاده از پردازنده های چند هسته ایی روی PC انچنان تاثیری نداشت ولی منبعد با اومدن DX12 قاعده بازی بهم میریزه . از قطره قطره قدرت سخت افزارتون استفاده میکنید ( چیزی که قبل از این هرگز روی PC امکان پذیر نبود )

درکل DX12 تا حدودی قدرت X1 افزایش میده
ولی روی PC انقلاب بپا میکنه مخصوصا ( با ورود بازیهای تحت DX12 ) کسایی که CF. SLI کردن تازه میفهمن دنیا دست کیه.

میتونی ولی نه به خوبی اونایی که پشتیبانی سخت افزاری میکنن فقط راندمان کارت و سی پی یو لبتاپت میره بالاتر
