Just pre-ordered the game a bit ago and while I was already going to do it regardless of my system (a laptop, yeah...I know) in order to support Obsidian and for more games like this to be made, I am a bit worried if I can even play it.
For reference I was able to play POE1 the whole way through expansions included and the only slow down was during a cutscene right before the final boss fight. The loading times however were atrocious though.
I'll post my system specs here if it helps:
Processor: Intel® Pentium® CPU N3540 2.16GHz
GPU: NVIDIA GeForce 920M
Disk Space is not a problem i have almost free 440GB in my HDD
