So I've installed the game, changed the .exe file to enable widescreen, but then I noticed the client is used my Intel integrated card. I tried manually overriding in NVIDIA driver menu, I manually changed the GOG client too, I tried directly from the game folder, selecting "Open with NVIDIA GPU" and still it won't use the NVIDIA card.

Any ideas on what I can try next? Thanks!

PS: Yes, I know that the Intel card can perfectly handle SC3000U. That is not the issue here
