Mike, about the +/- checkbox, in Options Preferences RealTracks, there is a checkbox that says "Use +/- RealTracks for Generation". If you UNCHECK this box and everything works fine, sounds good and the Task Manager CPU% does not peak well above 60%, then you could most likely (after a suitable period of testing to be sure) press the button, "Erase unneeded +/- Files". In my case, I did the "Erase" command on a copy of the files, and left the original distribution hard drive untouched, as a backup. Remember, unchecking that checkbox means you are NOT using the "old" style of RealTracks, so they are then superfluous if everything is OK.

About Geekbench, the forum does not have Geekbench reference numbers for machines that work and do not work with the new engine and RealTracks. We probably should start collecting that by anecdotal evidence.

We do know from another post that a PC of about 4 years old vintage with a score of around 1000 was said to work OK. A few others reported scores of 1200 and they did not say the new engine didn't work. Mine is a two-year old Core 2 Duo with a score of 3000. One user of an Intel I5 got a score of almost 6,000. Apparently, the number of cores you have is a multiplier, and BIAB does benefit from using more than one core.

What does it all mean about Geekbench? We won't know for certain until more users on the borderline like yourself report in that it works or does not work without the old +/- files.

One last caveat: if you do erase the old +/- files, you cannot then use older versions of BIAB with that altered RealTracks folder. Versions from 2010.5 and before require those +/- files. I don't know why anyone would want to use an older version after hearing the improvements from 2011. Even if they had an old and slow PC, they could check the checkbox and use the old files with the 2011 version.
