After learning about the CDLCs on this site, I purchased the PC version of Rocksmith 2014 and am thrilled to have gotten CDLCs to work with it. However, I am experiencing quite severe lag problems. [My PS3 version works perfectly, but my PS3 is not a type that can be modded to play CDLCs.] The problem is that the video display for songs lags far behind the audio. This video lag problem occurs with songs that came with the program as well as with CDLCs.
The problem is not with my amplification setup, because it still occurs when I just plug headphones into the computer. I am using a Gateway Laptop running Windows 10 with an Intel i5-2450M processor, which is quite a bit more powerful than the CPU that UBISOFT recommends. Is it possible that my laptop's "Intel HD Graphics 3000" is inadequate? [it works with video editing software.] I've noticed that when I play songs at 100% speed in the Riff Repeater, the lag is much reduced compared to "Learn a Song" mode, and the lag becomes unnoticeable (or nonexistent) at 90% or less speed. Does playing a song in "Learn a Song" mode use more computer resources than playing the same song in the "Riff Repeater?"
I found some online recommendations for "lag" issues, but to the extent that they define the nature of the lag issue, they seem to pertain to the problem of audio lagging behind video or lagging behind the actual playing of notes on the guitar, which is not my issue. Finally, it is not clear whether any of the recommendations pertain to lag issues which are not always present. Nevertheless, I tried removing the D3DX9_42.dll file after reading it may cause "lag", but this made no difference (other than disabling the CDLC songs).
Any ideas how I may fix this problem?
