Hey guys, is anyone else having major latency issues with the new game. If it makes a difference I'm usng the cable from the original Rocksmith game. I've tried HDMI to my surround sound receiver, optical to surround sound and hdmi to HDTV, and simply hdmi directly to the hdtv. When I hit a note on guitar there is about second delay between my hitting the note and the game playing it back. It makes it very difficult to play although I have been managing. Anyone else having this issue? Is there a difference between the original Rocksmith cable and the new 2014 one?

I also have some RS 2014 gameplay videos on my youtube channel for anyone interested http://www.youtube.com/RB3PROGUITAR

There is no difference in cables. HDMI will give you audio lag. You can use it for the video but get separate component cables for audio and you should have no noticeable lag. You need the audio signal to be analog.

Thanks for the heads up, I tried optical and hdmi but not analog. What concerned me was it's lag from my guitar, not the notes/music.

Yep Brick is definitely right - you need analog cables for audio. Cable it direct to an amp or stereo, something with no or minimal processing, and you'll get no lag. It's the same setup as RS1.

Digital signals get processed by the TV / receiver, and this adds lag.

In addition to the above note about using analog cables direct to your surround sound receiver, check your receiver manual to see if it has an option to turn off all effects/processing. Some receivers have a "direct" or "pure" mode which does this.

Switched to anolog cables and have the same issue. I have an Onkyo receiver which has the "direct" mode that disables all processing effects but I still get the latency. To me it sounds like when you're recording guitar on a computer without proper ASIO drivers or a crappy soundcard so your recorded guitar is delayed when compared to the track you're playing over.

I run my Xbox 360 to an older (no HDMI) Onkyo home theater receiver via analogue audio cables. Setting the receiver to "Direct" has improved audio lag. It's still not perfect, but I think it's the best configuration.

I have an Onkyo as well. When it's in direct mode there is still probably a little latency, but it's not perceivable.

I think any noticeable latency is down to PC settings. There's a rocksmith.ini file you can edit in the Steam directory which has a few extra settings the GUI doesn't expose as well as a PDF which explains what the settings are. One of those is the audio buffer size which defaults to 0 allowing rocksmith to try to automatically determine a suitable buffer. There's a chance it could be getting this wrong and ending up with a bigger buffer than necessary, so it may be worth trying different buffer sizes that are close to 0, but not actually 0 and where you don't introduce crackling. I'm using 256 at the moment.

The other thing to do is ensure both the RS cable and your output device are set to use the same audio format (16bit 48,000Hz). I would assume without this there would probably be sampling taking place that would increase latency a little.

With RS1 I could tell there was still some latency between plucking a string and hearing the result, but with 2014 it feels like it's instant at least when set in exclusive mode. In shared mode after tweaking it still feels like there's a very slight delay, but that could be me seeing confirmation bias of expecting it to be worse.

You also have this option from the main menu:

Tools (on the bottom of the screen) > Options > Visual Settings > Display Lag Correction


Once you get to Display Lag Correction, you can adjust the lag to better sync with your setup, like RS1 offered.

Hi, that's not the lag issue I'm having. It's a latency issue between me playing a note on my guitar and Rocksmith playing back the note. So I hit a note on my guitar and then 1/2second later I'll here it through my speakers. If you check out some of my video it's very apparent. I can still get good scores but whenever there's a lot of notes or it's a fast song it's really hard to play since I'm hearing the note twice.

Still having the issue. Is this just an Xbox issue? Are people on PS3 or PC having it as well or perhaps other people don't notice it...

Hi guys, this may help;

If you experience any noticeable latency with Rocksmith, then it’s more than likely due to the specific setup you’re using. Since everyone has a unique arrangement with their home entertainment systems, we’ve outlined steps you can take to avoid this issue.

If available on your TV, use the Game or PC mode setting. These modes bypass extra video processing filters to seriously reduce lag time.
If the TV does not have a Game or PC mode, you can diminish lag by turning off video processing filters. Refer to your TV manual for more information on how to turn off processing filters.

Check to see that the console is outputting video at the native resolution of your TV. If your TV’s native resolution is 1080p but your console is set to 720p, the TV must process the signal to scale the image up to fill the entire screen, which adds to the input lag.

On some TVs, HDMI connections can introduce more input lag than component or PC cables. If your TV has noticeable input lag using HDMI connection, you can diminish the lag by switching to component video cables or PC cables.

If you’re using external speakers, connecting the audio from the console to a stereo receiver or home theater system using analog audio cables can fix audio lag. To match the on-screen note display to the audio, you can advance the notes using the Note Advance calibration.

Thanks for the suggestions but why does nobody understand that it's not the audio or video lagging. There is a latency issue with the game processing the guitar and replaying the sound. I hit my strong and 1/2 second later it comes out of my speakers.

To be clear I have tried the following.

HDMI to receiver, receiver to plasma hdtv
HDMI to plasma hdtv, optical audio to receiver
HDMI to plasma hdtv, analog audio to receiver
Component to plasma tv, analog to receiver

HDMI to receiver, receiver to projector
HDMI to projector , optical audio to receiver
HDMI to projector , analog audio to receiver
Component to projector , analog to receiver

HDMI to 120Hz computer monitor, analog to receiver

All of these have the same issue. I have found a way to work around it but it sucks. I put my headphones on but not over my ears, that way I can hear the drums but I listen to the sound of my actual guitar, not my guitar through the game. I got platinum and gold on a bunch of songs this way.

I have two Xbox 360s and both work for Rocksmith with the following set-ups:

1. Component cable (universal) with video to TV (LG 47") and RCA stereo directly into sound bar (Phillips).

2. HDMI to TV (LG 40") and RCA stereo from universal component cables plugged into headphones (Turtle Beach wired). Component cables can't be official MS cables because they block off the HDMI output slot (because 360 doesn't handle both outputs correctly - do not switch TV inputs or turn off TV while both are plugged in or 360 will reset).

Universal gaming component cables are available at EB Games or GameStop for very little money ($10-$20). They work well.

Hopefully that's not too confusing.

I have one already which is how I was able to do HDMI with analog audio.......

On the PS3, I haven't run into any latency issues, and I'm running on the "not recommended" method of running video AND audio thru HDMI.

Where do I find the Note Advance calibration setting? i've set the video lag setting to 0 but there is still a slight lag in the test sound/visual. My real problem is the 1/2 second delay between me plucking a note and it sounding in the game. I am using the Xbox 360 component cable with the video input (R/G/B) and analog input (L/R) both plugged into the 'Component In' input on my Sharp LCD TV. Do I "have" to push my audio directly to/through a separate receiver to eliminate the audio lag? This would make for a very expensive Rocksmith accessory if you didn't already have one.

With my current audio lag the game is unplayable.

There is a log.
The minimum and most acceptable results I can get by using headphones (with no DSP).
The lag is very noticable on TV (in PC game mode without connecting a video cable, just audio 3.5mm jack) the same happens on receiver (either analog audio input 1,2 or aux 3.5mm)

Did anybody try to use (old style) analog amplifier(with no DSP)?
What results did you get?

Whatever you use you want no DSP. I use studio monitors connected to an external interface but any setup where the signal is not processed further is what you want.

I was having same issue strum string and delay between sound by quite a lot. I'm using Hdmi to tv optical from ps4 to surround sound system. Go to ps4 settings select audio menu click primary audio out to optical. Unchecked everything apart from linear pcm boxes. All Change bitstream to pcm. Got rid of delay completely ad not decoding sound anymore.
Hope this helps.

Your surround sound system could be adding lag.

Make sure it is set to stereo mode ... or try the audio modes to see which works best ... one should reduce the latency.


I think the bitstream setting (on any output device) is raw and should be the fastest. I think PCM is converting everything to stereo. Not real sure about that. Kinda confused about the whole bitstream vs PCM, but bitstream is what seems to give the best results and seems to auto switch between the source formats.

Had same problem big delay strumming guitar and hearing sound. Connect using optical to surround sound still unplayable. Go to ps4 settings then audio. Uncheck dolby and dts leaving just pcm boxes checked. Pick pcm instead of bitstream.
All latency now gone hope this helps! Works great now
