NVIDIA看片如果可以這樣，我可能會考慮看看...

DirectX Video Acceleration

DXVA2 implementations: native and copy-back

DXVA2 implementations come in two variants: native and copy-back.

With the native implementation, the decoded video stays in GPU memory until it has been displayed. The video decoder must be connected to the video renderer. There are to be no processing filter in between. The video renderer must also support DXVA, which gives you less freedom in the choice of the renderers.

With the copy-back implementation, the decoded video is copied from the GPU memory back to the CPU memory. This implementation doesn't have the limitations mentioned above, acts similar to a normal software decoder, but does require a GPU fast enough in copying data from the GPU memory back to the CPU memory; otherwise the result will be stuttering video playback.

Obviously, if a user has no need for customized processing, then it makes no sense to use the copy-back mode as the copy-back operations increases GPU memory load.

GPUs that should be fast enough are:

AMD: Radeon HD 6xxx and newer
Nvidia: Nvidia GeForce 500 Series and newer
Intel: Intel HD Graphics 2000 and newe

A家卡顏色加了多少料就不說了......

硬解4k什麼時候才要支援

LAV Filters 還是有些許問題

ati顯卡 同樣開DXVA快拉影片

MPC的DXVA沒問題

LAV Filters 有些影片可能會綠屏

一直沒有修正.........

當然這跟主題不相關,不過就這張圖來說,最近DX11的縱衡諜海-黑名單,開了Tessellation跟沒開之間的差異說真不怎麻明顯,但是開了倒是很吃資源

ati只是色調偏暖而已吧?
要說有多加啥顏色好像也還好

真要論加色很兇的是大型HDTV，一狗票接上HDMI後紅色豔到居然會溢色...



PS:ATI在早期仍內建實體影像解碼電路時的影像效果又不太一樣，除了顏色外還有一種細膩感又不會有模糊或太銳利的感覺

手上一個舊的NV 7800GTX公版卡，AMD HD6950公板卡同樣用MPC(K-Lite Codec Pack)在同一套軟體播放差異並不明顯，換一套放軟體後，改成Potplayer就與MPC有差異，但看影片我偏向選擇AMD，因為要改變顏色畫質的話，我喜歡Catalyst control center裡的多種調整配置。

我記得每改一代，AMD都會在播放功能上增加新玩意兒，但這次新款顯示卡似乎沒再強調？

不是每個人都能對自己的配備作色彩較正........

校色?

影片畫質又不是需要實體輸出的東西，校色主要是讓螢幕上所見與實體輸出色準一致

但影片觀賞會因為距離.環境亮度的關係使標準色看起來不夠活潑.艷度不足，不然TV這種較遠距觀賞得系統幹嘛刻意大幅增加艷度與亮度?

而且nv跟ati得影片相關色彩設定跟桌面色彩設定不一定是完全一樣，校色完還不是與影片設定脫鉤
