“ps1 根本就没有真正的图形处理器,ps1依然是传统的依靠cpu运算的游戏机”
这么扯的言论都出来了,我不 ...
因为那个时代,pc上有“双芯卡”这种很诡异的东西啊,物理上我还是一张卡嘛。另外,7900gtx也够了。我真的不觉得360和7900gtx的差距,和ps4 7870与7970的差距变化大。事实是什么,由于amd的战未来(垃圾驱动),7970在win下的性能从首发到现在提高了25%。所以那块7870性能并不是那么差,否则ps4也做不到能死撑到现在还维护在1080/30了,你看x1就守不住了。 当然,如果你是和7系列的泰坦/780ti比……那就差得远了……
好吧,我漏打了“3D”两个字
