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.

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)

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

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.

اصلا تاحالا باز داشتیم که آپشن 32x داشته باشه؟ اصلا بالاتر 8x رو نمیتونم تصور کنم :d

تمام قابلیت های DX12 روی سری 9 انویدیا کامل و بدون مشکل فعال هستند ؟

تمام قابلیت های DX12 روی سری 9 انویدیا کامل و بدون مشکل فعال هستند ؟

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.

اولین بازیای x1 که با dx12 ساخته شدن آخر امسال میان

 

[Terova]

هیلو 5 فکر کنم اولین بازی باشه باید دید چقدر DX12 تاثیر گذار بوده

 

[hamdi113540]

دوستان یه سوال:
الان کارت گرافیک nvidia 840m از directx 12 پشتیبانی میکنه؟

پشتیبانی نرم افزاری میکنه برای پشتیبانی سخت افزاری فقط باید سری 9 داشته باشی.

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

 

[OMG]

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

The Witcher 3 - CDPR Will Think About DX12 when its Available,Temporal AA Used on Consoles
اولین بازی که فکر dx12 باهاش تجربه کنیم witcher 3 باشه رو pc

 

[CS]

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 )

Spoiler

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
