FFT3DGPU跑这个cpu不满的话,显卡不够劲……
120fps……的确有些难为显卡了,推荐SLI/CF,虽然知道不支持的可能性高达99%(逃
我用的是和你同样的cpu,比你低一档的显卡。。。

120fps的时候应该不是压264吧……如果是的话绝对要请教一下avs和x264的设置

我不是说了是1st pass吗

……好吧,随便试了一下,1st Pass的:

关了fft也没有120fps[/han],不过开了也没下降几帧,CPU占用也没有明显变化,不过1st pass都没跑满就是了(60%-70%)
恩,没事上了下doom9:http://forum.doom9.org/showthread.php?t=139838
看来1st Pass跑不满4核是x264的限制
fft3dgpu也是要耗cpu的,并且是单线程的,你可以试一下在avs里加上MT(我记得我原来试过,rpwt很严重),如果这样的话fps还是有明显的下降,那就应该是显卡的瓶颈了

不能因为是q6600就不超频。。。我是超到3g在用的
我的3850明显频率比你的3870低很多

确实,超3G、关AQ和PSY的确能上120fps,不过我一般跑CQ,而且TESA+merange 32,所以就那可怜的x-1x fps(上10需要超频)显卡再慢也够用了
话又说回来,3850也很能超的,超到3870的水平应该是小菜一碟
