Hello so I just bought my own Dell Inspiration 3847 brand new, I downloaded Arma 3 after installing my antivirus software and everything in the campaign runs good. It's at 30 FPS with mostly standard settings but I tried going to multiplayer twice and both times the whole thing just stopped and froze when it was still loading the servers! It got to about 1000 servers then it started to lag and eventually froze. I searched for the i8347 and didn't catch any in these forums so I was hoping to get some info. I'm willing to replace any parts inside the computer because I know people that could help me with it but I'd hope you guys here could tell me what I need to be doing! When I went shopping today I made sure that the desktop could pass the required and even some recommended aspects but maybe it's our old Berlkin internet. I gathered all the info that came with the computer that I know of. The i8347 comes with Windows 8.1 and I even updated it before downloading arma. It has 1 TB of space 7200 rpm hard drive 4th Gen Intel core I5 4440 processors 8GB DDR3 3.1GHz cache And it has the Intel hd integrated graphics
