Yes this = behavior (of losing PTR cache after a single PTR playback session) is speci= fically when using RMFS to do the PTR. If you turn off RMFS altogether or s= et RMFS to be render queue only then the PTR cache persists fine.

My boot drive is a 256gig SSD drive with 130gigs free and= I had AE disk cache set to 60gigs of that drive.

Here is what I think your problem is, your machine is starved for RAM - = with dual hex CPUs that's 12 physical cores (or 24 virtual!!)

yes, the AE Mem&MP Pref panel shows 24 processor cores

chewing through RAM - I have a 3930K (single hex) and I ha= d to upgrade to 64GB RAM to get decent preview length at full resolution in= 1080p

coup= le things you can try:

- try lowering amount of RAM per core in MP setti= ngs (to 1 or 2 GB per)
- Try previewing at lower res (third or quarter)

in = troubleshooting it I had already dropped to SD resolution (and even that at= half rez) and had the RAM per core set at 2GB and then even 1 GB but the p= roblem still happens
=A0
- turn OFF hyperthread= ing on your CPUS in the BIOS OR limit AE to use 6 or 12 CPUS in MP settings=

I just set i= t to use 12, then only 4 CPUs by boosting the number of "CPUs reserved= for other applications" in the AE MP prefs but it still loses PTR cac= he (BTW the only other app I've ever had running simultaneously with AE= is Google Chrome but I did even try quitting that to see if it had anythin= g to do with it but it didn't seem to)
=A0
- buy mor= e ram. Honestly I would suggest 128 GB minimum for your setup

it's a p= ossibility I'll be adding more RAM to this machine, but I'm unconvi= nced that the source of this particular problem is the amount of RAM instal= led (or RAM available when running AE)

= Anyway, I DO appreciate your suggestions and would welcome any more ideas y= ou or anyone else on this list has to offer.
