Hey no need to apologise! I'm running a Radeon Vega 8 in a laptop so I wouldn't usually be surprised if it used up a bunch of power, but this little dude can run most games from 2015 decently. I've tested the game on a much more capable Nvidia card and it uses around 400mb of VRAM. Could be some extraneous processes running in the background of the game? Thanks for your reply :D
