Hey, can someone tell me how to unlock the DX11 and High Res Textures in settings?
I have my original PC DVD-ROM Limited Edition copy and the game can still patch
itself to v1.9 but I can't unlock DX11 or High Res Textures.

Crysis 2 is my fourth favorite video-game (behind Shadow Warrior 2, Quake III and F.E.A.R.)
I want to play the game (in its complete state) again in 2020 on my new PC.

I'm hoping somebody here can help me.

Cheers!

First of all, you should know this if you want to play:
