Lag Part 2, if you're looking at this first, then go here for part 1
Lag Part 1
Television Lag Reduction
Some TV brands have a special "video game" mode that will switch off all the fancy filters and processing so that it reduces video lag and improves game to button reaction times. If your TV does not have them, then you need to set up a visual mode for it. I can't help with every TV, you're learning guitar, I have faith in you being able to figure out your TV. Just go through and turn off your cinema modes, your auto-colors, your dynamic contrasts, your dynamic volume. Digital noise reduction is a HUGE no no when it comes to gaming. After all of this, you may need to use the Lag correction option inside the game to slow down or speed up the game, depending on how much an improvement it makes.
Signal Checkpoint Reduction
As I mentioned before, you can have a long chain of goings ons. The worst that could happen in a typical home would look like this:
PS3 > HDMI > TV > HDMI > Receiver > Speakers
That's got the signal being Encoded and Encrypted twice, de-crypted and reshaped twice, and converted at the end. We have to cut down on this.
Best option to reduce audio lag is to not use digital audio at all.
PS3/360 > analog cables > Receiver > Speakers
The PS3 and 360 can output analog, your Receiver/amplifies the signal to your speakers. The Receiver can be a stereo unit with an input, it can also be some headphones. Every PS3 comes with a set of RCA cables. You only need the white and red audio ones. You can then go into sound options and choose your system to "multi-output" so that audio comes from your HDMI and your Analog connection. This will cause an echo with your TV, so simply mute your TV and listen to the sound coming from your Stereo/Receiver/headphones.
The problem here is that not everyone has a receiver(I don't) and perhaps not every stereo has RCA connector inputs(mine doesn't). Here is what you need:
RCA Female to 3.5mm Stereo Plug
It is less than 50 cents, and shipping is under 2 bucks. I hook my White and Red audio cable into that, put it in my audio-in(MP3 player hookup on some stereos) and I'm set to go. Alternately you can use this to plug into your smart phone and record yourself playing very cleanly.
I can confirm this works. The game's lag feels similar to my actual amp's lag, which is pretty imperceptible to me while playing cords. Without this set up, using HDMI sound, the delay would mess up my strumming patterns, and I could not play as fast as I was able because the delay kickback would bother me.
Here is a component cable for the PS3 that will work, its under 5 bucks
5 point Component cable for PS3
Use that with the RCA>Stereo dongle, and you'll be doing great. Remember you have to activate the audio to be sent in both signals using the PS3, and you'll want to mute your TV so you don't hear echo.
EDIT: If you have speakers for your computer that are plugged into a power outlet, then you have a "receiver" built into them. You could plug the stereo jack mentioned above into them and it will be just as good as the connection I personally use.
Day 14
Holy crap 2 weeks? It does not feel like I've been doing this for two whole weeks.
I am working on learning a song inside Rocksmith. I have not chosen which I want to do to 100%, but I'm trying several different ones. I have to really like the song to put this much effort into it this early on. I do not think I can get 50% difficulty and be satisfied till later. Candidates so far are Last Dance with Mary Jane, You Really Got Me, and Sixteen Saltines.
While auto-wah>chorus>reverb made me feel like a rock star, palm mutes and power chords make me feel \m/etal. I am a huge 90's metal fan. I basically considered Dimebag as my less well behaved older brother I never had. My friends and cousins used to watch the Pantera home videos, it was like Jackass before Jackass in a lot of ways. Lots of metal that I find I like does not have the super squealy guitars like the 80's metal, it has the palm muted chugging riffs of the 90's. I palm mute practiced for at least an hour today. Pretty much the same things over and over, but that's how you get muscle memory.
I have a leg up on the Power Chords. I knew how to play "Brain Stew" by Green Day for years. It is a power chord, and so my fingers already have that shape memorized. I have also used that shape while practicing the intro to "Clean My Wounds" by Corrosion of Conformity, a riff from their guitarist Pepper Keenan. Pepper Keenan is one of the top riff masters of today, you can also hear him doing the slow/sludge thing with Phil Anselmo in the metal super group "Down". Look up Stone the Crow and Eyes of the South for songs by them.
Tomorrow will be another day I can devote several hours to playing, and now that I have my new lag-free set up, I'll be wanting to put it through its paces.

Explaining Lag Part 1: and Day 13
Explaining Lag.
Ok, I'm going to come at this from a semi-starting angle. When people talk about games, there are several types of lag. One is internet lag, this is caused by a slow connection. Ideally this should never come up in Rocksmith, awesome, one less thing, right? Ok. The next is graphical lag. Unless you're playing on PC, there's not really much you could or need to do. The 360 and PS3 versions of the game were tweaked to make them work smoothly.
The one that Rocksmith has to deal with is Interface lag. Technically the previous two types can cause this type as well, but as I said, not a big issue with Rocksmith on PS3 and 360.
Signals come in two basic forms, Analog and Digital. Analog is a way of turning wave patterns into electrical patterns and back again. The conversion is generally imperceptibly fast in doing so. The problem with sending these analog signals is that certain wave patterns can get lost, static wave patterns can be introduced, and even outside signals can interact with them. Put your phone beside a computer speaker, you'll start hearing a "beep beep beep". Because of this, there ARE better, more expensive analog cables, an entire industry has arose around providing better analog connections.
Digital signals are these waves patterns converted into ones and zeros. These ones and zeros can take up alot of space in the digital world. Most are "compressed", made smaller by reducing similar signals, so that they can travel over a medium. There's another thing that will many times come into play, encryption. Netflix, Redbox, and all the Bluray people do not want you to be able to record their content while it is going through a cable. So the signals are encrypted. After all of this, the TV gets control as well. Compression can cause low resolution videos to get splotchy, so manufacturers put filters to reduce it. Colors could be set up for your specific screen, so now the manufacturers add color toning, skin whitening. The audio might be 5 or 7 channel audio, but your TV is 2 speakers. Now they have to convert that, and many times emphasize the signal that is used for voices. So you have signal production, signal coversion, signal analyzing and compression, signal encryption, signal travel(speed of lightish), signal reception, signal unencryption, signal uncompression and reassembly, signal alteration, and finally signal output. Got digital out from the TV to your speaker system? Well add ALL those steps again before your digital reception device outputs into analog speakers. All of this takes milliseconds each... but add up to have pretty significant delay. I am even missing a few steps here, but you get the general idea.
The bonus is that there is no such thing as "better signal" from more expensive cables. High grade HDMI cables are a rip off. Digital signals either work or don't, there is no signal loss. If the cable is long enough(we're talking multi-room length), there will not be a shitty signal at the end, you'll either get 100% full audio/visual or 0%.
That's all for today. Tomorrow I will talk about reducing each type of lag. If you are reading this on the bleeding edge of reality and want answers NOW, then read the insert that came with Rocksmith or go to Ubi's site.
Day 13
Kind of long, I played a lot today. It was 4 degrees outside my door today, which is strange this close to "Hotlanta", So a lot of stuff to cover...
I think I may be coming to a crossroads here. I have been purposefully going slowly through the lessons and not going through the other stuff fast either. I wanted to make sure I had the basics down before really getting into the stuff I can not do. Also, playing songs at an elementary and unrecognizable level is not fun for me, and I do not feel accomplished. Add to that my notorious dislike of spending time on music I do not care for.
So, I have choices. I want to continue using the Guitarcade for practice, and I want to continue doing lessons that matter to me. The thing is, I think there is a lot of songs that will help me out a lot more than what is included on this disc. Is that still keeping with the spirit of the 60 day challenge? Is there a point to keeping a blog for the challenge if I'm deviating? There are songs that interest me on the disc, there's a lot of them, there's also like 20+ DLC songs that would interest me. I just do not know if I"m good enough to even attempt Thunderkiss '66 or Mary Jane's Last Dance. Like I said, the game just giving me random bits and pieces pisses me off more than helps me out. If its a freakin' power chord, give it to me; I can do power chords. Don't make me prattle away.
What songs do I want to learn? Well, I learned about a few Pentatonic based songs that I have played a long with in Youtube(without actually learning the correct sequence to the notes, but knowing they "fit" in with the music). There are also a lot of simple chord songs that would help me out on that end, and they just aren't in game. I'll think over it tonight.
Today in lessons, I worked on the Hammer On/Pull Off practice track a little today. The next lesson was Tremolo picking, and I found out that I could not care less about Tremolo picking. I have always hated 50's surfer music and beach blanket bimbo style cultural stuff. So yea, I'm not going back to tremolo picking any time soon. I did, however, do the lesson on palm muting.
FINALLY. A new breakthrough. The first since day 01 I would say. I always wondered how people like Rob Chapman, and every metal guitarist ever, got that "thud thud" thick sound. The video showed me how I was supposed to be using my palm to still allow sound through, but make it sort of muffled. I had always though "Palm muting" was just a regular mute technique, nothing really musical. This lesson kind of made me feel dumb, but I am glad I finally know. THIS I will have to practice, THIS I will be using in my own playing eventually. THIS is what i have Rocksmith for.
TIP OF THE DAY
Listen to them when they tell you that tensing up actually works against Tremolo picking. After giving up on the lesson, I did practice just relaxing my hand "just right" for the picking to work at all. To my surprise the notes got faster, rang out clearer, and sounded more accurate.
