I bought the Digital Deluxe edition of Crysis 3, and want to play through the Crysis 2 campaign first, but I'm getting ridiculously bad DX9 (no high rez textures) performance. When shooting at surfaces my frame rate drops to as low as 30, and I'm running this game on a GTX 590.

I've been told that downgrading to version 1.8 of Crysis 2 solves all the performance screwups introduced in 1.9. How do I do that? I'm thinking of disabling the "Automatically keep my games up to date" option in Origin and then re-downloading and re-installing Crysis 2, and updating it to 1.8 myself. Would that work?

Thanks to those who help.
