Hi guys, Long time lurker on these forums, I have finally purchased a piece of NI midi hardware, the F1. I was previously using Traktor LE that came prebundled with my VCI-100 and a audio 2 DJ. I have seen plenty of posts about latency issues with the new version of software which is not ok but I'm sure will be addressed by a patch shortly. However I do want to ask if anyone has any suggestions for my issue, the main reason I ask is that even downgrading back to LE or my friends copy of 2.1 which came with his S2 I have the popping sounds. Previously on LE I had no problems with latency or certainly not as noticeable as now. I have gone through the full traktor optimization guide and killed plenty of services etc that I had running. My laptop is a MSI 660R, i5-460 2.53ghz processor, 8gb of DDR3, OCZ 240gb SSD boot drive and 500gb hitachi SATA for music storage. I am using the audio 2 DJ with version 3 software, I have tried downgrading this also to see if it made a difference which unfortunately it did not. I have seen a lot of posts in relation to keylock also, I have tried eco and high quality and I have tried completely disabling yet I still have the issue. Both DPC and Latency mon record my latency at sub 500ms, average of 180ms. I am very close now to formatting my laptop as I have a gig coming up but I'd rather not obviously, any suggestions would be much appreciated!
