我不介意他流程短难度低,但是帧数30就是不买。
或者说我用词不准确吧,30帧对比60帧,是那种幻灯片的感 ...
Just found an interesting read regarding the de-flicker/blur-filter:
https://ppltoast.wordpress.com/2 ... ecubes-copy-filter/
It's mainly about Dolphin, but helps shed som light on the topic.
"Swiss, when set to force 480p on games, also disables the deflicker filter"
"FIX94’s Nintendont on Wii also disables the filter when forcing video modes"
So it seems that forcing the sharpest possible picture out of Gamecube games is possible when running on either a Gamecube or Wii using Swiss and Nintendont respectively. However, does anyone know to what extent Wii games running in 480p are affected by this "blur"-filter?
For whatever reason, the European Wii version of Twilight Princess was supposedly much blurrier than the North American version, even when both were captured with 480p component.
I tested on Dolphin and took a couple screenshots from both versions to compare. The sharpness was completely identical. Just what the heck was going on here?
After pondering for a few minutes, I recalled something that my eyes had glanced over in phire’s original pr:
2) Deflicker filter. The game does a vertical blur across 3 lines, blending the odd and even fields together which minimises the flickering effect inherent to 480i consoles on interlaced TVs.
This is why 99.9% of games render all 480 lines each frame even when rendering at 60fps.
The filter is counter-productive for progressive displays, which is why dolphin hasn’t implemented it before now, though it does blur away the dither pattern.
A built-in deflicker filter for interlaced video? Could this be it?
I fired up the Dolphin build with Stenzek’s pr implemented and took more screenshots to compare. Bingo.
