Game is still playable but the fps drops are kinda tedious. Not experiencing anything similiar with other games. This Fps drops happen no matter the graphic settings and no matter what's happening in game (can be perfectly fluid with 1000 mobs on screen and can be stuttering without any mob in sight). Also i get a mini-freeze (1-2 seconds) every now and then.
Well, while your graphics card isn't ideal, it shouldn't be causing you problems, and you shouldn't be getting bottlenecked by your CPU either, which leaves me to ask the question of what generation is your ram? Is that 4 gigs of DDR2 or 3? Either way that's a very small amount of ram, and depending on your OS you could be left with only 2 gigs to play with. Depending on your setup (like what motherboard you have) I really recommend upgrading your ram, it's fairly cheap. You'd be looking at less than $70 for sure for 12 gigs of DDR3.
Sorry lol, i was checking my configuration to give you the info you needed and i just noticed i've got 8 gigs RAM (not 4). I play on win7 64 bit (i have the option to upgrade to win10, but i dunno if its good for gaming).
i5 3570k is a 1155 socket chip, and that architecture only supports DDR3, Bleu42. However, you can still install a 32-bit OS, but that's highly unlikely the case.
4GB suffices in most use-cases. Some games requires larger amounts (although his GPU should bottleneck before his RAM), and some games are more sensitive to the speed of the RAM rather than the amount.
D3 is just poorly optmised, and that's almost exclusively the cause of FPS drops apart from poor hardware specs. Some GPUs have had driver issues, especially AMD (surprise!), so maybe you should try to upgrade your driver. I think they just recently managed to fix the desolate sands bug for instance.
There are some threads over at reddit you could check though, and try each different tip on their own to track what changes actually have an imapct on your performance:
1. Lower your audio setting to lowest (16 channels) in the in-game audio settings. This may sound stupid, but have fixed the FPS drop issue with heavy screen clutter for a lot of players.
2. Tick the Max FPS checkbox in the graphics settings, set it to 60 and tick the Vertical sync checkbox. Also tick the max background FPS chechbox to prevent the system from using excess amounts of power to refresh the background/ambience.
Exactly, i have been only having these issues with diablo, heroes of the storm and even heartstone (fps drops when i open packs). All other games are fine. I'll check out what you said @Fehfeh, but i think i already tried it.
