270X在MAC下性能低下
RT，我用的是HIS的R9 270X，免驱，但是在系统报告中显示 的是7xxx，所以用坛子里的那个AMDFramebufferUtility改了下FB，显示为270X，是正常的。我的CPU是I5 4590，本来是四核四线程，但是在cinebench跑分软件中居然只显示双核四线程！CPU的跑分比WIN下低了50左右还可以接受，但是GPU在WIN下跑FPS是接近100的，但是到了MAC下却只有56，表示实在是无法接受，初步怀疑是CPU的原因，特来向各位请教以下几个问题：1、是不是由于CPU只识别了俩核导致测GPU性能的时候桢数只有WIN下的一半？
2、如果真的是这样要怎么解决？

以及跑分图：
我也是看起来都很完美，但是性能比win低，CPU少了10左右，GPU少了30-40 {:5_278:}我的5770也是，性能比win差多了，无解啊，凑合着用，反正os x不玩游戏的 280x也是不过低了一点而已，当时游戏时候能感觉出来 cou分数倒是一样4790k 280x也是不过低了一点而已，当时游戏时候能感觉出来 cou分数倒是一样4790k 貌似不是白果的显卡性能都被削得很惨 我朋友也这卡，通过修改FB后正确显示，但是仍比Windows下低了将近1/3的性能，对A卡更加谨慎了，以后还是N卡玩玩得了。 I3-4160 + XFX 270的

N卡Maxwell架构的用web driver驱动的性能照样比windows低了很多，并且10.11下不支持metal渲染 a528589980 发表于 2015-9-23 10:52 http://cdn.pcbeta.img.inimc.com/static/image/common/back.gif

好高的跑分。。请问层主是怎么驱动的 请叫我官人 发表于 2015-9-23 09:48 http://cdn.pcbeta.img.inimc.com/static/image/common/back.gif

n卡也这鸟样 我280X 只有73换过各种FbNameframebuffer 390x 不换任何fb 不修改任何东西 4尼妈跑分108fps 符合心里预期了！反正跟win比少1/3可以接受！反正游戏也没几个这个卡足够跑了。 用r9 380（4G）同样不修改任何东西跑分98fps。。。我了个去 qinhuashu 发表于 2015-9-23 13:30 http://cdn.pcbeta.img.inimc.com/static/image/common/back.gif

哦？我的N卡跑出来没任何区别。 请叫我官人 发表于 2015-9-24 07:58 http://cdn.pcbeta.img.inimc.com/static/image/common/back.gif

哦？我的gtx 970跑分低，难道是老黄要完蛋？学大众？ qinhuashu 发表于 2015-9-23 16:02

不用改id！所有接口正常 qinhuashu 发表于 2015-9-24 20:49 http://cdn.pcbeta.img.inimc.com/static/image/common/back.gif

不用修改FB 吗 xiao1234567890 发表于 2015-9-24 22:55 http://cdn.pcbeta.img.inimc.com/static/image/common/back.gif
不用修改FB 吗
不用改都正常 只是显示不正常而已
跑分还很高。。。
