hi iq_132,
thanks for the reply!
The specs of the test machines are:
1) c2d 2.66, 2g ram, ati hd2600pro (256m dedicated ram), win7
2) intel e5200 2.5, 1g ram, nvidia 9500gt (512m dedicated ram), win xp
3) Athlon x2 2g (real clock), 1gb ram, integrated gfx, win xp
Anyway, the game, while running on some stages, has periods of frameskipping where you can notice it more:
1) chun li
2) ryu
3) guile (not too frequent)
Here you can clearly see that the characters sprites tend to skip more frames than expected, sometimes suffer of a very short "teleport" effect, hard to notice.
Thank you again!
