RadeonBoost可能是此次改版亮點.
沒想到從2016併購案後晚了3年才來
尤其對於中低階GPU,與正要上市的
7nm 筆電APU
故事拉回2015-2016,
當年有家冷門公司叫HiAlGo,專利軟體優化,去偵測鍵盤滑鼠與繪圖API的變化
然後用Code-injection方式改變繪圖運算
優化GPU耗電或流暢度.
不同優化目標稱為Chill/Boost/Switch....
缺點是它跟遊戲或驅動沒有整合,
外掛注入修改程式的技術常被判定成病毒
所以沒啥市場.
201606另一家冷門公司AMD把它併購了
HiAlGo Chill 被改稱 Radeon chill
用於畫面低動態時 限制最大fps省電降溫
201612的AMD Relive驅動開始實作Chill
(需在白名單的遊戲)
但AMD主力客戶在PC,對省電降溫
其實不是那麼在意,所以加分有限.....
201912 AMD驅動出現RadeonBoost
這應該就是官方整合版的HiAlGo Boost
當年的技術展示

很屌,HiAlGo當初目標是賣軟體外掛,
垃圾內顯或文書裝機卡也能跑3A.
Boost是用於動態+FPS不足時,
它在移動動態大時調整降低解析度,
藉以提升FPS.
原理跟家機部分遊戲常用DynasRes動態解析度類似.
家機少數遊戲在1080P跑不到30fps時,會動態下修960P甚至更低. 超過fps再調回來. 但
家機做法通常跟畫面動態無關.
只是低於30hz就硬拉fps,畫質改變較明顯.
因為靜態也可能物件多而跌破30hz
靜態畫面跑30或90對玩家根本沒差,
那畫質劣化卻被凸顯....所以PC遊戲少用.
(家機所謂優化沒有什麼黑科技,
大部分都類似這樣東西,選擇性犧牲)
HiAlGo專利是在它會偵測鍵盤滑鼠API等
各種變化,決定什麼時候啟動優化.
理論上對畫質影響較小.
因為畫面轉動很快時,你本來就看不清楚
小動態或靜態畫面則盡量不去影響.
例如PTT跑fps不到30,也無感沒差...
RadeonBoost大概也是AMD測過分析過的
白名單內遊戲才能支援.
最適合靠它嗑藥boost噴fps的,
大概也是APU或低階卡.
本來大作跑不快,開Boost有機會流暢.
甚至可以噴50-100%,
看你大動態時願意犧牲多少%畫質.
會用裝機卡或APU的大概也沒有血輪眼
AMD: 聽說有人自認那XP風格驅動值5K?
那我這嗑藥boost爆氣版該值多少?
NV:冷門公司 冷門卡 冷門功能
Who care?
