Ok, so... I tried to install the driver and guess what?
Error: The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer’s manufacturer. Setup will exit.
SO, I went to Intel's FAQ and it told me to download it DIRECTLY from Acer's website, I double-checked it and the newest version for Intel HD Graphics there is version 2104.
So basically I can't play it because Acer is outdated.
I'm very upset about it, but still I thank you because your advice was correct.
I just sent an email to Acer asking for the authorized new drivers, let's see if they will deliver it someday...
Edit: I searched for alternative ways to download it, even though it's not validated, and I found on Intel that if I download the ZIP version of the driver, I might be able to install it (generically) manually.
I'm trying it out now, will come back to tell you if I was successful
Maaaaaaaaan, I'm so upset, theorically the computer installed the new driver, but I didn't believe it.
And still, in the hpl.log it says that I have version 2104 instead of 2361, so I don't know what to do! I reinstalled the game and had no success yet
(Also, I've already rebooted the computer)
