There is no issue... I was just comparing my two laptop's performance both
are Dell, one is core-i5 with ATI 1GB dedicated memory and another is
core-i7  with Intel HD 3000 graphics

so just checking the performance and tried the glxgears command and seen
the big difference in FPS
I always found the output of glxgears quite confusing, to say the least. If
you think logically --- your screen displays a picture 60 times in one second,
and some graphics cards (like Intel) render the frames in the same rythm, to
display the images of the gears animation 60 times per second.

OTOH, there are graphics cards like ATI, which render cca 4000 gears images
every second, out of which only 60 get to be displayed on the screen, while
all others are skipped. I find this to be a terrible waste of card resources
(and energy), without any benefit whatsoever. That is, assuming one can
actually trust the glxgears output numbers.

good clarification .... thanks




And in spite of the above, people generally consider the 4000 fps to be
"better" than 60 fps.

myself too..

I never understood this. But then again, one cannot
understand everything in life anyway... ;-)

thats the low of nature ...no one can understand everything


Best, :-)
