Yes= this behavior (of losing PTR cache after a single PTR playback session) is= specifically when using RMFS to do the PTR. If you turn off RMFS altogethe= r or set 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 dis= k cache set to 60gigs of that drive. I just tried switching the cache drive= to a 2TB HDD with nothing on it and increasing the cache size but it didn&= #39;t avoid the problem. I have another SSD drive I'll be installing wh= en I get a chance.

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

yes, the AE Mem&MP Pref panel shows 24 processor cores
=C2=A0
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

but my problem is not (so far) with the duration of PTRs I'm gett= ing, but rather that once the PTR is built (and the timeline shading indica= tes it is cached) it is gone as soon as I stop the initial PTR playback -= =C2=A0once it shows as cached with green in the timeline=C2=A0it should=C2=A0be cached till something changes, right ? (shouldn't that alwa= ys be true?)
=C2=A0
couple 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 trouble= shooting it I had already dropped to SD resolution (and even that at half r= ez) and had the RAM per core set at 2GB and then even 1 GB but the problem = still happens
=C2=A0
- turn OFF hyperthr= eading on your CPUS in the BIOS OR limit AE to use 6 or 12 CPUS in MP setti= ngs

I just= set it to use 12, then only 4 CPUs by boosting the number of "CPUs re= served for other applications" in the AE MP prefs but it still loses P= TR cache (BTW the only other app I've ever had running simultaneously w= ith AE is Google Chrome but I did even try quitting that to see if it had a= nything to do with it but it didn't seem to)
=C2=A0
- buy more ram. Hon= estly I would suggest 128 GB minimum for your setup

it'= ;s a possibility I'll be adding more RAM to this machine, but I'm u= nconvinced that the source of this particular problem is the amount of RAM = installed (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.
