谢谢各位的回复!不过我还有一些不确定的地方希望能有更详细的建议。
我平时主要看的电影和视频是24帧和30帧,
目前的1660可以做到37ms在nguSharpVH,满足一部分24fps内容的播放,就是有点吵,nguAAvh则需要平均48ms才能处理一帧 ,不考虑补帧,这也是我希望单帧的渲染时间尽量能控制在30ms以下的原因。
在[url=https://www.chiphell.com/thread-2274087-1-1.html]chiphell一位用户的帖子[/url]里,3080仅作倍线时的单帧渲染时间在16ms到20ms之间,这对没有看60fps视频需求的场景来说无疑是一种巨大的性能
钱 浪费,因此才提出询问2070s~3070区间的性能表现。所以可以的话,希望各位能具体秀一下1k视频倍线到4k时的frametime,也方便日后做一个参考。
反正台机不用放在桌面上,风扇起飞了就扔墙角去 另一个令我在意的地方在于对这些内容谷歌的时候得到的一些难以验证的内容:
“madvr使用16bit integer纹理,所以比起对游戏性能提升很大的fp32,显卡的int16运算能力在这里更重要;”
如果上述推断是真的,那么A卡和RTX20系可能要比同规格的GTX10系或RTX30系更适合madvr,这些卡的int16运算能力要更强一些。
来自5ch,有一个madvr相关的专楼 ...
例:
[quote]ゲームやらずにmadVR用でグラボ使っているぞ madVRはINT16で処理してるから実質Radeon一択になったな RTX2000のINT16はFP32の2倍の処理能力があったけど RTX3000でINT16はFP32の等倍に戻ったしな RadeonはVEGA世代からずっとINT16はFP32の2倍ののままで RDNA2でもそれは変わらない[/quote]
不过类似的说法我只在5ch上看到,反而是英语论坛用“madvr”,“int16”,“fp32”,“rdna”等关键词搜索并没有什么收获,只不过是确认了madvr确实有默认用16位整数处理画面的流程:
madvr使用int16纹理 ...
摘自[url]http://forum.doom9.net/showthread.php?p=1632165[/url]:
I'm using 16bit integer textures by default, which have the benefit of using all their accuracy on the important 0..1 range. Yes, 16bit floats are relatively fast, too, but they stretch their accuracy over a *much* wider range, which means that in the area which counts the most (16-235) they have a much lower accuracy compared to 16bit integer. If I had to use floating point textures, I would have to go 32bit floating point by default, in order to not compromise accuracy. So the decision for me is not 16bit integer vs 16bit float, but it is 16bit integer vs 32bit float, and that's a quite big difference in performance.
Ok, if I went with floating point, people could compromise by using 16bit float instead of 32bit (trade quality for performance). They'd probably get identical performance to the current madVR logic, but with slightly faster subtitle rendering. On the negative side, they'd get less accuracy at the same speed as the current madVR logic. I think that's a bad compromise. Furthermore, if you look at the high quality option, I'd have to use float32 instead of int16, which costs twice the memory bandwidth. So the memory bandwidth cost of doing Jinc3 AR for a "no compromise" setup would double. All of that just to get a small boost in subtitle rendering performance? Sounds like a bad idea to me...
以及确认了Madshi这几年研究出来的madVR Envy播放器里面塞的是2080Ti,豪华版里是3080
看一眼信用卡余额 如果有持有6700xt及以上级别A卡的朋友愿意分享一下使用情况的话,将是极大的帮助。
