[tehs]

Hello, having really near unplayable low fps the last week its ok when doing solo content like Mushin (50-60) but when i am in a dungeon or doing anything with 4 or 6-man the game gets unplayable i get 15-20 fps on bosses and it drops down to 1-5 when they are activating red circles or do other fancy stuff , support has been no help AT all

windows 10 64-bit
4096MB RAM
Processor: Intel(R) Core(TM) i5-4430 CPU @ 3.00GHz (4 CPUs), ~3.0GHz 
Graphics: Nvidia GeForce GTX 750 Ti

Even reducing all settings to the lowest changes nothing absolutely nothing so please help me i want to have fun playing this game again

Maybe get more ram? At least 8gb should be plenty. Update graphics drivers? Also clicking "Ctrl F" to hide other players will greatly help.

Get more ram, install win7. If you dont want to get a new cpu, theres not much you can do.

 

Unpark cores

For my computer since I run 6 GB of RAM and a 512 MB graphics memory cache card, The least I can recommend is turning your graphics to around 3 to2 on all settings and disable motion blur and run in a 1200 - 800-ish window size if your PC supports that.

General Basic Things To Help Your Game Performance

• Disable Windows Aero Theme if on 7, If on 10 just use generic basic windows theme
• Set Windows to Performance over Quality
• Unpark all your cores ( THIS IS A MAJOR WAY TO BOOST FRAMES )
• Don't let your AV scan during Gameplay, if you have one it and it is scanning it takes up a lot of resources.
• Stop any processes you do not need to free up some memory

• Get an SSD ( Won't help Frames will help the "flow" of game/loading )

• Use the Latency Fix http://us.battle.net/d3/en/forum/topic/5578595314 ( has possibility of reducing ping by 10-15 or more depending on your location from server )

• Lower Resolutions = better performance

• When Fighting in large PvP / Boss's you can try to lower everything in game to lowest of low if you are having 10-15 frames but it probably won't do much

• Press Alt+Enter a few times to enter True Fullscreen mode, game performs better in it
