If i may ask - what is your SSD model and is it your main drive [the one that your OS is on].
And do you use the strict pagefile - and by strict i mean set to custom amout so it is not fragmenting itself.

Im curious because moving the game to ssd fixed all those strange issues for me [and by no means - this is not the fix for this issue, hope larian look into this, i would prefer to keep a 30+gb game on hdd that have 1tb space not on ssd with 120gb =P].

My SSD is my C drive with my win 7 ultimate as my OS.
I have set my pagefile to 8192mb, equal to my physical memmory and its a strict set min 8192 and max 8192 [this prevents the page file from fragmentation, sure it does not matter as much on an ssd drive, but i use this trick for around 15+ years, it always worked like charm in terms of os stability and mem management]

My SSD model is ADATA SU800 128GB SATA3. Not the fastes thing man ever prodused but its not a bad one either =P
