最近看到VEGA56狂降價
真的證明只有賣不出去的價格= =
我當初我是買msi公版56
後來受不了那個鼓風扇
弄了一体式水冷套件改裝
所以現在變成了這樣

下面那張是開核過的藍寶RX460
由於上了水冷套件
我目前是直接刷上水冷64的BIOS
https://i.imgur.com/yAVQyuf.png
當初買公版就直接是爽爽爽的VRAM
水冷64預設時脈達到1750 電壓1250
這樣的頻率跟電壓對56其實太高
目前我的設定是這樣
https://i.imgur.com/KC0WbMD.png
跑個Time Spy
https://i.imgur.com/CPADHGP.jpg
GPU頻率再往上拉可以到71XX
但拉到極限其實蠻不穩定的
回到madVR來
其實要跑madVR其實也是種壓力測試
降壓超頻3DMark能過的設定
未必madVR能過...
尤其看個電影都要1個小時起跳
madVR演算法開好開滿長時間滿載
除了耗電跟廢熱還有可能熄火畫面直接黑掉
所以一定要用影片解析度來對madVR Profile設置
關於madVR詳細設定真的要花時間去萬年冷凍庫看完且理解
現狀跑FM因為BFRC支援madVR使用Zero-Copy模式
使得單卡補幀效率高很多
但BFRC硬解10bit影片會有bug
BFRC設定內硬解功能關掉會比較好
由於我現在使用的是4K螢幕
我會以我現在的使用狀況來說
單卡補幀 720P>4K的狀況
我的設定如下
https://i.imgur.com/TxuEs4B.png
https://i.imgur.com/9qaSJP4.png
https://i.imgur.com/s6ZJWju.png
基本上亮度翻倍開到 NGU Sharp high 2X即可
或許有人會想為甚麼不直接翻4倍
因為補幀下翻4倍VEGA56會吃不消
720P翻4倍解析度超過4K
還要額外花效能將影像降頻到4K
其實720P翻兩倍也到了2K解析度
配上RCA去消除壓縮失真效果已經足夠
何況NGU Sharp配RCA不需要消費額外效能
還可以自由調整強度
簡單的效果比較

還有這個一定要調
https://i.imgur.com/g5KxbvI.png
error diffusion 其實對顯卡消耗蠻多的
而且很難看出差異
維持ordered dithering即可
這樣設定實際看完一集動畫功耗如下
https://i.imgur.com/MjN2Rgp.png
平均功耗128W 最高186W
因為我上水冷平均溫度53度
空冷我想壓在70度以下應該可以
由於我色度升頻開到NGU Sharp high
選擇Bilateral soft、Reconstruction soft功耗會少一些
單卡補幀 1080P>4K的狀況
我的設定如下
https://i.imgur.com/BpFIpOu.png
https://i.imgur.com/hgiYZXZ.png
https://i.imgur.com/aBIaQfp.png
https://i.imgur.com/FMiRW4T.jpg
實際功耗
https://i.imgur.com/AfbjMSB.png
平均功耗165W 最高功耗211W
平均溫度60.9 最高溫度62
可以看到1080P翻倍升頻4K就真的吃資源了
由於跑madVR時開始幾秒功耗會升高
後續才會平穩功率還是有機會破200W
4K的影片由於亮度不需要翻倍
影片品質也都很好
色度升頻也不用選擇太高
補幀下去基本上功耗75W以下
基本上目前影片還是1080P為主流
1080P能開翻倍到4K足夠使用了
當然上水冷後的VEGA56設定還能再往上調
不過再往上追求得到的效果提升有限
搞的電腦像火爐是本末倒置了
VEGA56現在12K的價格
想要單卡補幀跑madVR是很划算的選擇
抽到海雷的我想也不要灰心
我的madVR設置就算不超顯存也能跑
就不知道非公版版本空冷的實力
有勞其他人測試了
