Diablo 3 lag

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

Diablo 3 lag

Sorry for new topic. :?
So even with G-sync monitor Diablo 3 stutters as hell for me. :oops:
My specs:
i5 2500k @ 4400mhz
20gb ddr3 1800mhz
Gtx 1070

What have i tried:
1. Limits fps to 130\120\110\100\90...60, with <60 it's nearly unplayable (Background stutters like hell, 30 fps lock looking like slide-show in this game)
2. V-sync on\off both driver and game.
3. G-sync windowed and fullscreen.
4. Max pre-rendered frames 1-8 and use apps default.
5. Disabled overclock on cpu, gpu, memory.
6. Changed motherboard, ram, gpu (580-780-1070)
7. Turn OFF G-sync
8. Game on SSD, tried move it to WD black and even to USB 3.0 flash drive
9. Clear install OS and change os (Win 7, 8.1, 10)
10. Different drivers with G-sync support from R340.52
11. Disabled and minimised all game settings (Video, audio, social)
12. Disabled all background apps.

Looks like G-sync not working at all in this game.
Here is some gameplay video.

Just look on slomo recording, it's pain... :oops:
Some strange moment - while recording via ShadowPlay, it's VERY SMOOTH (Record, not gameplay during recording)
All other games working nice with G-sync.
Can it be fixed or it's game engine problem? :(

Just a test: does switching to 60Hz mode fix it? Do do that, set the "preferred refresh rate" setting in the nvidia panel to "application controlled" and switch to 60Hz on the desktop. Test it with g-sync OFF, in-game vsync ON, nvidia panel vsync "use 3d application setting."

Result: Same. It's looks like frame skipping or smth like that on the BACKGROUND. Character moves smooth in all situations, just look on the video. Stutters only on background, while movement of character is silky smooth. :oops:

Doesn't D3 have two separate frame limiters? One for the background, one for the foreground?

Yeah, it have separate limiters, but foreground limiter is for "while app is minimised".
But i tried to turned it both on\off, set various limits to both and still it's same, while it >60.
When it <60 (50 or lower) it's like hell on Earth. I played many games with 30 fps lock, but even 40 fps in this game is unplayable.
But, but, but... Character have smooth movement, but background...For "Top down" game it's unplayable mess with frames.

@MaxiJazz

You're complicating this a bit. This is a G-SYNC forum...

What we'd be trying to figure out here, is if the stutter is only happening in G-SYNC mode. Does it? Or does it disappear when you disable G-SYNC? From your post, it sounds like it happens with or without G-SYNC.

G-SYNC can't cause stutter, but it can't eliminate all forms of stutter either.

I looked up "Diablo 3 stutter" on Google search, and I got a lot of hits:
https://www.google.com/search?q=diablo+ ... 8&oe=utf-8

It's likely the game itself, G-SYNC or no G-SYNC.

Some games just stutter no matter what you do. G-SYNC can't fix all microstutter or frametime spikes. It only fixes the standalone V-SYNC stutter that happens when your framerate locks to half your refresh rate and back (60 FPS to 30 FPS, 144 FPS to 72 FPS, etc), that's it.

Read my "What are Frametime Spikes" section here for more details on system-caused stutter:
