That is an interesting point you bring up. Theãmachine is running an i3-4000M with a 2.90x4 CPU, but I don't know that it isãattempting to use them all or not.

The i3-4000M is a Haswell architecture, the iGPU doesn't support
QuickSync decoding for h.265 in that generation, so it's doing CPU
decoding, which your system *should* be able to handle, but it's pretty
high overhead, which would account for stuttering, and will vary based
on memory and hdd performance as well.

From other messages (i3-4000M) QuickSync does have h.264, but not h.265 hardware support, so you are correct in your assertion... I did take the
time to check.

Intel Skylake (5000 series) added hardware h.265

It *appears* that theãissue may not be the hardware I am playing back on, but the power source Iãwas using while recording. I still need to retest 90fps but, at 60fps offãthe battery pack, I recorded video that played back without issue.ããThe video I took that had difficulty was taken when the camera was pluggedãinto my car's power vs. the battery. I did not take that intoãconsideration.ããI am testing 90fps from battery source right now so we will see whatãhappens. :)ããon edit - nope that wasn't it after all. Apparently 60fps good, 90fps bad!ããã * SLMR 2.1a * Backup corrupted: (A)bort (R)etry (P)anic (H)ammerãã---ã þ Synchronet þ CAPCITY2 * capcity2.synchro.net * Telnet/SSH:2022/Rlogin/HTTPã
