I used to get loads of 100% accuracies when I owned a Charvel DS2 ST loaded with a 9v Active Humbucker and routed with a TASCAM US-100 with the raw input boosted to the rocksmith realtone cable. Since switching to PRS, using passives and the guitar is plugged straight from the RT cable to the USB port the ONLY song I have ever gotten 100% accuracy on is the stock game song "Are You Mine? - Arctic Monkeys". This game is very fun to play with actives and an interface acting as a preamp, hit registration is actually flawless, but playing it as intended and with passive pups, is meh even on a high-end PC running at max settings, 1080p, 144hz with Nvidia Gsync enabled. Interface input boosting works different than the in-game audio boost option, in the sense that, you can really drive up your signal without losing your trebles and note definition, infact it makes note dynamics far better. Also, the rocksmith cable is high-impendance so you naturally lose your trebles, I think the interface trick actually makes your signal low-impendance, which means most of your guitar tone is still there when it reaches the game. The best thing I remembered from playing with this configuration, is that sustain was amazing, you try performing a full step bend and vibrato and get it to sustain in rocksmith for 7-8 seconds..... not happening. With the interface as a precursor, its easy as pie, almost like having a tubescreamer apart from, it does not distort clean tones in the game if you tune it to the correct +Db.
