How is everyone? I hope you all do fine...been a while since my last visit.
This may be not related but the latest update of my AV caused some problems with other programs...
Some of them show increased memory usage in Taskmanager, saw this post and thought you guys might face the same issue with skinstudio.
Open Taskmanager and take a look at the processes tab and see if Skinstudio is eating up an abnormal amount of RAM if so whitelist the application in your AV to resolve the issue.
This strangely worked for me for other older apps...
Might be not the case for you but worth a try, otherwise try and run it as Admin... to see if that changes anything.
If your physical memory is full or the capacity close to be fully utilized, the running threads that need memory to do operations may write to your physical hard disk instead if the RAM isnt available, you can observe this if you open Taskmanager --> performance --> recourcemonitor -->then RAM
on the right side there should be a live graph or several, whenevery this shows a "hard error" a thread has requested data (pages) from RAM that has already been paged out to HDD or SSD and now has to be loaded back into RAM.
if this happens often this is an idication that you need more RAM.
