It helped a bit but not much and I'm not playing on a laptop or a potato either. I really hope they address this issue.A minor edit for people with performance issues:
Go to Karryns_Prison_v5g_EN\www\js\plugins and open RemtairyCutIn in notepad or notepad++ (don't forget to make a backup of the file first and place it somewhere outside of the script folder)
Change on lines 6-9 everything to 0 to remove the image shifting during combat cut-ins.

I don't have an estimate how big the impact is on performance of older systems because my own performance was all over the place during testing.
