PERMEDIA3非专业试用手记

前记：首先必须说明的是我并非3D工作者，所以我将从一个普通玩家的角度来看待耕宇的PERMEDIA3（图1），请在座的3D高手见谅。

按例交待一下硬件环境：

pII496（124×4）、6VBA2（98下安装4.19主板补丁）、192M sd（运行在124mhz、cl=2）、火球九代6.4G×2、NEC 5500A DVD-ROM、S90声卡、美格xj810显示器（设定分辨率为1280×1024@16bit、85Hz，以下若无特别说明，均同此项）为便于比较，我还准备了一块G400DH。

接下来说明软件环境：

Win2k 中文2183，安装DX7；测试软件为Q3正式版和最新的OpenGL Benchmark version 1.6.2（图2）；PERMEDIA3和G400驱动如图3、4、5。

Win98中文SE；测试软件为3DMARK2000和Video2000（DVD播放软件为Windvd2000），及Treemark（采用TreeMark -tltest -depth8 -lights6命令行）、PERMEDIA3和G400驱动如图6、7；PERMEDIA3支持的特性如图8；很奇怪采用pcilist显示PERMEDIA3运行在agp 1×，而expertool则显示为2×（如图9、10）。

Win2K

Q3 Demo001：（分辨率为1280×1024，其余设定同HQ模式）

G400：17fps

PERMEDIA3：8.6fps（采用了针对Q3的优化项）

闻道有先后、术业有专攻，看来PERMEDIA3真的适用于专业用途噢（不过它在1280×1024@32bit、85Hz分辨率下的清晰度曾令我眼晴一亮，当时有将此卡据为己有的罪恶念头）！
