- All tests are done using US turbo 2
- shmupmame setup is stock except speed setting changed to 99%
Fei long stage time comparison
ps2 hyper street fighting
ggpo final burn alpha turbo 2
ggpo final burn alpha turbo 1
ggpo final burn alpha turbo 0
As you will find out below, final burn alpha has 2 more frames of input lag when playing offline on a lagless CRT.
2/60 = you are deprived of 3.33% of a second to react to any moves.
With turbo speed set to turbo 1, the game is 2.67% slower overall. But it still does not feel as responsive as arcade.
With turbo speed set to turbo 0, the game is 4.95% slower overall, you have enough time to react but your input will still come out slower.
And that was for offline with lagless CRT. Most LCD has lag. Also when online lag comes into play, you can see that playing at a slower turbo setting will be better.
