Never saw this program in action and I'm trying to find better solution for gameplay recording than current Fraps (I admit I hate it) so I'm wondering something and best idea for me right now before buying Mirillis Action! is to ask someone who use it for some time...

Rig that would probably host Mirillis Action! is quite capable: Core i7 OC @ 4GHz, 24GB of RAM, Intel 520 SSD 120GB for sistem + additional HDD for data storage, GTX 660 2GB GDDR5... and I think if it's possible for Mirillis Action! to record gameplay directly to RAM memory (not to HDD or SSD) to some kind of temporary buffer storage (let's say 12GB of that 24GB), virtual RAM storage drive or something like that and when gameplay recording is complete to "throw" that recorded material from RAM to HDD? Is this possible in any kind of recording software like MA, to buffer whole recording session (few minutes of recording) only to RAM and later to send it to HDD (I don't want to bother SSD with jobs like this) or that function still don't exist in MA and similar recording software? Or maybe better solution is to use MA in conjunction with some kind of third-party software (for creating virtual storage drive out of RAM)?

Blutaar, fVic's, someone...?

There is not need to record to RAM, even when recording to normal HDD there is not loss in FPS. I have this program and it works like a charm.
