New discovery: Xbox 360 version of sf4 series has different timing from arcade/ps3/pc

So much for not responding to my posts anymore. Weak.

None of your tests are relevant, because they weren’t done on official arcade hardware. This will never change.

Just because the timings didn’t change in any of the tests you did on your different setups, does not mean they are the exact same as on arcade hardware. The logic doesn’t follow. Any of the things I listed could (but do not have to) impact input timing. The possibility exists for there to be differences in timing on the arcade hardware, which automatically makes your tests flawed, and they will remain that way, unless you prove, scientifically, that your setup matches input timings of arcade USF4 exactly. Which you cannot do, simply because you do not have access to an official USF4 arcade cabinet (monitor included).

@LeRaldo its ok to not agree with someone, but you’re trying too hard to discredit what he’s doing, i dont totally agree with his result but he has some points

@LeRaldo I think you’ve gone overboard with the technical stuff if we apply your technical analysis then we can’t be sure all Xbox 360/PS3 console hardware revisions are the same. By your technical standards this makes comparing SF4’s differences cross platforms irrelevant because the slightest change in hardware/software will affect the performance and input accuracy on the same platform !

That’s not the case at all. If you actually read what I said, it’s not at all a certainty that the timings have changed, only that it’s a possibility. That’s what makes his tests of using an arcade rip on his own PC, instead of an actual arcade machine, flawed. Until it is scientifically proven that an actual arcade setup matches EXACTLY to his own arcade rip on PC with emulated JVS I/O, his tests are meaningless. And you cannot test this without an actual arcade machine.

And yes, for thoroughness, different console revisions should be tested against each other to be sure they have the same input timings, if they haven’t already. Because it is theoretically possible that they could be different. And they should also be tested under different kinds of stress, such as being on for many hours, having a lot of different sticks/gamepads plugged/unplugged, higher than normal heat, etc. But that can come afterwards.

Yeah that’s true especially when CPU/GPU’s exceeds certain temperatures the performance is reduced that might result in lag. I remember we had an older 2 Player SF4 Taito Type X2 cabinets that went online like laggy and we found out the network switch between the 2 cabinets has overheated.

So yeah I agree with you many variables can introduce input lag. Problem here is we can’t say for sure which is the definitive standards for perfect input accurate port the community went to the Xbox360 because of it being the most responsive port.

Many glitches and hardware defects could introduce input lag. My original point was to show that under normal operating conditions ps3, PC, and arcade have matching input timing and that the 360 runs faster due to vsync problem’s on AMD cards with the sf4 engine. If we just want to play on the most responsive platform regardless of the reason then we should play on PC with vsync off exclusively on crts which would be even faster than 360s on evo monitors. I don’t remember tournaments of super turbo or hyper fighting being played with the maximum turbo speed possible. I believe turbo2 or 1 was the preference because that’s what the arcade defaulted to.

I’m fine with 360 being the standard, I just wanted to show that under normal conditions it is running faster with a more varied input timing than the other versions because of an issue with its gpu with the sf4 engine. I could easily adopt my own play to this without much difficulty (more reliance on quick reactions and speedy moves and less on zoning and visual links). My personal opinion though is that we should play on one of the other versions that don’t have vsync issues and appear to match the arcade.

Can I prove 100% beyond any doubt that my set up running the arcade version has the same timing as a standard vewlix cabinet? No, but I believe I’ve made a good case that their is no good reason it wouldn’t. I think the fact that it exactly matches the PC and ps3 version speaks for itself. Anyways, its just a matter of time before I get a chance to record an actual Vewlix cabinets input timing. A standard vewlix will be either on a 1 frame delay monitor or 2 frame, I’ll be sure to record which model it is and add the difference to equal my evo monitor, and then we’ll see what the result shows.

If anyone wants to do their own tests or experiments feel free.

werent the latest Xmania games played at Turbo3 speed? Speed appeared on the game screen

we played on PC with friends yesterday, they never played the PC version before , they only play on xbox , both told me that it was too fast, and i had Vysnc on, then i disabled Vsync, it become unplayable for them

By unplayable I assume you mean way too fast? They might be used to playing the 360 on typical HDTVs with 3-5 frames lag compared to your monitor but I get what you’re saying. Its definitely worth looking into since the 2 frames faster issue hasn’t been rechecked since the Super era. I’m leaving on vacation in 2 days but when I get back next Monday I’ll borrow a 360 from a friend and test with a high speed camera to double check that the 2 frame faster speed is still the case in Ultra. I know the speeds match on sf x tek though the 360 version has to screen tear to match the proper speed.

You never know, maybe the 360 version was slowed down to match the other versions since Super (about when the 2 frames faster was observed). That would be a welcome discovery.

i mean, the input was too fast for him when i disabled the Vsync, he couldnt even do simple Ryu combos, and he has better execution than me, just like what happened to me when i tried xbox version the first time

and no we usually play on computer monitors when we play on xbox, never use TVs, also you should wait Ultra release on PC before testing, at least you can be sure they are the same version

I happen to have extensive knowledge on this topic, and 90% of what you said is 100% false. The 360 version isn’t FASTER because of a limitation…you don’t need a degree to figure that one out. The xbox version is by the far the most responsive iteration of this game and this is probably because it does have V-Sync disabled. Vertical sync causes input delay and weird joystick/mouse acceleration issues (common knowledge in PC land). I’m sticking with the better version(xbox).

Extensive knowledge huh? I guess the PC, Arcade, and PS3 versions have proper V-Sync enabled in order to show how superior the 360 version is without it. Hell I guess the Arcade machine versions of Street Fighter 4 just have V-Sync enabled as a sort of buggy weird beta version of the game in anticipation of the V-Syncless xbox version. In fact now that you mention it I guess almost every console and arcade game from the NES era on had weird joystick acceleration issues due to V-Sync. Also I assume by “common knowledge in PC land” you are talking about all the random fps bro-information that is flying around the internet and also has common nuggets of wisdom such as deleting wallpapers to improve input lag. I guess game developers, computer scientists and video technicians don’t know exactly what effects V-Sync has (fixes juxtaposing frames,screen tear, and frame randomness at the expense of a few frames of input lag). I guess what you’re referring to (weird acceleration issues) isn’t commonly known to come from the damn mouse acceleration and smoothing settings and have nothing to due with arcade stick inputs or V-Sync.

This isn’t Counter Strike or other common pc shooters where the game’s engine isn’t locked to the frames and the community decided to play from day 1 with V-Sync off. This is a damn arcade game and arcade games have been played with V-Sync since before PC gaming was anything more than fucking Oregon’s Trail. I’ve had enough of responding to every idiotic post that is spewing random shit that they think is technical knowledge because they’ve read it on some fps forum full of 15 year olds. I give a warm heated thanks to those that understand what I have been saying and also to those that brought useful counter points or information to my knowledge that might warrant looking into. I did my research and testing in order to bring new information to the community that I thought was important. I’m leaving on vacation tomorrow with my girlfriend and family and I don’t anticipate responding anytime soon to weak posts spewing random shit or attacking me with any tiny detail they can find to prove me wrong because their inner console fanboy was hurt. If anyone has important information, actual knowledge, or genuine questions I will get back sooner or later. GGs. Peace out.

xbox does have Vsync and input lag, the only way to avoid tearing without Vsync to my knolwedge is to run the game at 120fps/120hz, wich is not possible on xbox and without a monitor that have a 120hz refresh rate

Regarding Taito X input lag and Tetris the Grandmaster Challenge
The keyboard input hack causes input delay

Though you can even make your own custom Taito X boards and reduce input lag even further
