なるほどー.
一応,PAE 外したカーネルでテストしてみました.いずれもドライバ等更新し
た環境で kernel 2.6.28.9 です.
(PAE あり)
$ glxgears
Failed to initialize GEM. Falling back to classic.
2082 frames in 5.0 seconds = 416.285 FPS
2085 frames in 5.0 seconds = 416.895 FPS
2080 frames in 5.0 seconds = 415.832 FPS
(PAE なし)
$ glxgears
get fences failed: -1
param: 6, val: 0
11539 frames in 5.0 seconds = 2307.626 FPS
11549 frames in 5.0 seconds = 2309.737 FPS
11523 frames in 5.0 seconds = 2304.558 FPS
確かに効果ありますね.ただ,速くなったと言っても Google Earth はそれな
りにストレス溜まりますが.^^;
