So I downloaded Arma 3 latest update ( with 64 bit version). Wow my FPS is gonna be slightly better now? No? I run arma 32 bit on 40 fps. When I start it up with 64 bit my fps is 10. MY system is 64 bit I have i7 4720 and 8gb of ram. Can anyone tell me if there is anything wrong with my pc or?
Are you running A3 on a laptop?
If so, it seems like your laptop is running A3 using the integrated graphics (Intel HD Graphics 4600) instead of your discrete graphics card (GeForce ???/Radeon ???).
To tell your laptop to run A3 using your dGPU (not your iGPU), try right-clicking the shortcut to A3 and see if you don't get some option to "Run this application with ???"
