PS3 / 360 - SF4 System lag. What is the definitive answer?

The only problem I have with that video is that is was recorded on a 30fps camera and if you pause the video at :06 you can already tell its out of sync. Hell pause it throughout the video and you can tell its off. Is this system lag or bad sync up of the jumps from the tester? Who knows.

So is SF4 the only game with 1 frame? Anyone notice HDRemix,MVSC2,Tekken6 or Blazblue lag?
I know we’re only talking about 1 frame here, but that’ll always be in the back of my mind whenever I screw something up (which is a lot!).

This thread makes me wanna cry. Like when I found out PS3s lag when playing PS2 games.

As long as it’s fixed in super

please be fixed in super

I wonder if the developers are reading this discussion.

I didn’t know that this existed, until today. I have played on both systems and really didn’t notice any difference.

I would hate to see the tourneys ran on XBOX 360 and worry about RROD, but at the same time, people don’t want to play on the PS3 because of this.

Can it be fixed by patching?

Is this just SFIV or is the PS3 itself reading inputs a frame later?

Was there a comparison with the arcade board, or were only the 360 and PS3 compared against each other on the Vewlix display? All display output and input 720p?

i feel that 360 is faster; whenever i go from ps3 [which i normally play on], then play on a 360, i miss things that i normally hit 100%, like a simple bnb.

Is everyone sure it’s not the output display settings on the PS3? The only way to do a true test would be to output 720p (1280x720) on a 720p native monitor. The other big problem is that virtually all 720p LCD’s and plasmas have a computer resolution of 1366x768 or some other offshoot. The Xbox can output that resolution over VGA and HDMI. The PS3 cannot.

I just finished testing lag differences between the PS3 vs. 360 on my G15 plasma. It’s mostly a test run for when I do the test a bit better with SSFIV, but my results do suggest that the PS3 has one additional frame of input lag.

  • cables, wouldn’t it be more accurate to also set the Xbox360 to 720p to eliminate the 720p>1080p upscaling factor that is happening by the TV? That way, you would be able to rule out the resolution scaling as the reason for the 1 frame of lag on the PS3. Of course, even if that was the issue, the Xbox360 would be better suited for people with 1080p TV’s.

Yeah, that’d be better for testing 360 vs. PS3 input lag. I was being sorta self-centered and trying to figure out the least amount of lag for my own setup for each system. If it means anything at all, I get nearly identical results in RB2 auto-calibration tests when outputting at either 720p or 1080p from the 360.

I might do the 720p version of the 360 test this weekend, but more than likely I’m gonna wait until Super comes out to be all rigorous.

From what I hear from vVv Scrub, the PS3 is closest in speed to the arcade version since both run at a slightly slower speed than the 360 version.

The difference is enough to affect a player’s performance if they were to play on a console that they don’t play on often, so for the sake of tournaments where the console used isn’t always standard, it’s best to own and play on both consoles.

i think this ^^^ is the most important thing to do for all serious tourney players.

i know that everyone wants a standard, but that isn’t the case and probably won’t ever happen. The best way to combat that, is to own both systems and practice on both.

I for one can definitely tell the difference between the 360 and PS3. I originally owned just a PS3 and ended up at a few 360 tourneys where I just couldn’t get my timing down at all. I eventually went out and bought a 360 just so I could practice SF4 on it for any 360 tournaments. Now, I exclusively play on the 360 at home now (because the timing just feels much better than the PS3), but when going to a tourney that is all PS3…I will spend the entire week before the tourney playing on the PS3 so I can get readjusted to the timing difference.

Wouldn’t a simpler test be to just hook both systems to a CRT (thus eliminating the possibility of lag from the TV) and check that way?

What matters is testing at the same resolutions on the same displays with each system. If you do the 60fps test for Xbox360 vs. PS3, and do it on a 480i SDTV CRT over composite cables, then your test data is valid for that setup. It doesn’t tell you what happens at 720p, so you also need a 720p test for both systems. Does it lag differently using HDMI out than analog VGA/component out? You can see there is not a simple one-test answer.

So far the evidence-based consensus seems to be that PS3 has 5 frames inherent lag, and 360 has 4. I’m curious what the arcade hardware shows. vVv scrub seems to think PS3 matches the arcade more closely, but I dunno if there’s any general consensus or if it’s ever been tested.

Is less better? Well, consistent is better. All of our games (including arcade boards) have some sort of inherent input delay, and they do tend to vary by the machine they run on. It’d be nice if SFIV were consistent across the board, but we can at least know for sure which system has what properties.

See NKI’s CCC2 input lag test thread for an example of varying lag on different systems, including arcade hardware.

read Shinsho’s post in this thread.

doesn’t shinsho say that 360 is closer to arcade? wtf…

double edited my post with more explanation.
plus i don’t assume stuff!

He never said he tested the arcade board for lag, just that he used the Vewlix-F display/cabinet. He might’ve been assuming that the 360 was closer to the arcade in terms of lag because it was less frames, but that is not necessarily the case.

he updated his post so it seems to be correct. i dunno i always missread things anyway…

most of the time when i see the issue’s like this come up it’s simply because the people using the system are unfamiliar with xbox360. personally i don’t own a ps3 and i allways watch people sit their confused trying to get different controllers to have control of different people where as i know for a fact i could do it far faster by using the 360 and just swapping sticks 1 at a time.

on top of that the 360 turns on and loads up the game FAR faster than ps3 does so imho it doesn’t make that much sense to run majors on the ps3 for any reason other than that is the system that most TO’s are used to. only potential annoyance for 360 is if someone doesn’t properly turn off their wireless controller after a match, but that problem can come up for ps3 as well, and like i said the 360 loads up much faster.
