我这里目前用8800GS的速度和GTX280的速度一样,估计程序还没有优化好。NVIDIA说未来的软件版本可以做到480x360接近200fps的压缩,现在是130fps,720p可能可以做到100fps。
“They’re the world’s leading designers and manufacturers of CPUs – how hard could it be to build a GPU? I mean, come on, how hard could it be? That crummy little company down the road builds them – we could build them in our sleep. Come on, how hard could it be?” ——NVIDIA David Kirk
拿不同的编码器来比速度,本身就是PR的思维。
起码也应该拿rate-distortion的图出来看看是不是quality一样?或者说白了,画质差多少?画质基本相同的情况下的速度差别?
目前的版本只是提供了baseline的压缩,所以要比速度的话,基本上只能是用baseline来对比。
