Hi Sherbyna,
The game is graphically more demanding.
4GB of VRAM should be enough, but everything should be set to lowest graphical preset. Unfortunately I can't tell how well will the game run, but I saw some players playing it on some older notebooks with lower specs.
The game will most probably look a little "rough", screen resolution should be reduced and frame-rate would most probably won't reach fully smooth values...
If the game run slower on start, give it a little more time to load resources (everything should be ready as the game intro cutscene finish, but move camera around a little to trigger loading of additional resources)
The game is available for free so my best advice is to download it, start it (no game installation required) and set everything in settings to low. Try if the game is acceptably playable for you.
*first loading might took a little longer
Hopefully you will be able to run and enjoy it.
