The running background processes aren't an issue. As you may see on the attached file, they have very little consumption when out of game, except for the 43% memory usage, which in game goes up to about 80% or so. I've fired up the MSI Afterburner OSD to see if anything was bottlenecking performance and found that GPU was fine, I don't really recall how much usage, CPU was also okay with around 35-50% usage, and RAM, although around 80% or so usage shouldn't be an issue since it didn't max out. HDD was also tested with about 3 different disk software (CrystalMark,HDTachometer, WD Digital Data Lifeguard, both Quick and Extended tests) which were all found out to be clean, HDD is okay too. I can't really see what could be causing this except for maybe a connection issue (I don't see how connection would affect map loading but it's never out of the picture). If there was a way to check in-game ping it'd be great so if you can tell me anything about that it'd be gladly appreciated. Apart from all that I'd only blame it on the game as there are atleast hundreds or thousands of other users with this problem, which EA should really look into fixing, maybe on patch or update, or maybe just making the map load as a whole (as GTA V does) before the user is able to play, atleast I wouldn't mind it.
Further input will be appreciated, thank you 🙂
Edit: I have turned Shadowplay OFF and ON and on both occasions the bug still happened so that's not an issue, as with the GPU drivers, they've been reinstalled and updated and it's still happening. Turning down video settings also doesn't help.
