1,7 GB is pretty huge... you might wanna be aware that on 32-bit systems, you physically can't use more than 2GB of memory at once, including what the OS is using. I hope you're dynamically loading and unloading resources during the game rather than loading all 1,7 gig at once at startup, otherwise chances are your game will have lots of random crashes on players with low-end hardware.
(For instance, GameMaker:Studio does this by default, and the GMS1 runner is 32-bit, so it will have this issue for big games even on a 64-bit system)
