D3 - Mouse Broadcast Not Instantaneous?

New ISBoxer here. Great software, thanks for making it - surprisingly easy to use with a bit of reading/watching.

When I am shift-moving (I don't click move), there is a noticeable lag (say 150ms or so) between when I move my mouse on the foreground character and when the background character moves. This can result in annoying separation of characters going through doors, around corners, etc.

I am running two characters on a single laptop (Aorus X3 - Intel i7/Nvidia 870M). Native res is 3200x1800. I am running my D3 instances at 1280x800x60 (Windowed (Fullscreen)). I have everything off (including VSync, AA and Max Fore/Background FPS) and am using the lowest available fx settings etc.

I have tried limiting framerates in foreground and background at 10, 30 and 60 and it makes no difference. Similarly, I've tried various of the CPU strategies in the CPU wizard, but it makes no difference. I've tried it at the lowest resolution available (800x600), but it makes no difference. I've tried wired and wireless mice, and it makes no difference.

Any ideas appreciated - if this lag is normal, I'd love to know...!

Many thanks for your help.

In CPU Wizard at initial setup, I tried using 30/30 max FPS, but every time I go into CPU Wizard now it is reset to 60 foreground / 30 background - it doesn't matter if I change it and save it, it reverts back to 60/30 when I open CPU Wizard again. I have FPS foreground and background limit set to 30 in the Inner Space configuration (is this relevant?!). While I can change the max foreground and background FPS settings if I edit the character set parameters directly, it does NOT show up when I then run CPU wizard (ie CPU wizard shows 60/30 again).

The CPU Wizard doesn't read what is already set on your Character Set, it just starts off with a set of default values when you first open it.

Similarly, if I try to set the CPU strategy to "round robin", it never seems to save via CPU wizard - is there some other way to set round-robin CPU strategy rather than trying to use CPU wizard?

You can manually adjust framerate limits and CPU affinity in the Performance tab found under each Slot of your Character Set.

Is this broadcast mouse "lag" to be expected?

It is not.

Is it likely related to this "stuck" 60/30 fps differential or not being able to use CPU round-robin and - if so - any ideas how I can force 30/30 and/or CPU round robin strategy in the CPU Wizard?

It could easily be related to framerates, and as I mentioned before, the CPU Wizard uses a default set of startup values, but is actually applying any changes you make to your Character Set through it.

You may also want to monitor what your hardware is doing during all of this to see if a potential bottleneck is causing the delay - http://isboxer.com/wiki/HOWTO:Tweak_you ... ottlenecks

MiRai, thank you very much for your prompt reply, it is much appreciated. I actually figured the wizard was starting on default values, so I've now tried various framerate limits (10 up to 60) and different CPU strategies - but none of it has changed the lag.

Given it still lags even with a 10 framerate limit, isn't it unlikely to be a framerate issue?

The lag is apparent in the login screen - it's not something that only appears when the CPU and/or GPU are especially stressed.

It was my first guess, sure, but it could be anything really.

At this point, I'll say that a diagnostic may provide more insight as to what may be happening. However, while the instructions say to get a diagnostic running outside of Inner Space, I would suggest providing one outside of Inner Space, as well as one with your Character Set fully launched on the login screen (and maybe with Repeater enabled) so that we might compare the two to see if anything sticks out.

Ok, I will do the diagnostics. What do you mean by "with Repeater enabled"? Thanks again.

Broadcasting turned on, which is usually the default for D3.

You might also want to share your config, because your Window Layout might be creating 3200x1800 windows despite what your ingame settings are using. viewtopic.php?f=22&t=13

Here is the paste file from the diagnostic for game crashes (Diablo III.exe):

Here's the paste file from the diagnostic for game crashes (InnerSpace), without any D3 instances being loaded:

Here's the paste file from the diagnostic for game crashes (InnerSpace), with both D3 instances being loaded:

Anything strike you? Cheers!

First, you can try going into the registry editor (Win+R > then type in 'regedit'), navigating to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers, and removing anything listed for Diablo III.

If that doesn't fix the issue, then you can begin shutting down the numerous programs which could be interfering with something. Some programs, like AVG, will require a full uninstall and restart of your machine.

MiRai, thanks again for your sugegstions. I've removed a couple or registry entries in that folder related to D3, and I also removed all those programs you highlighted (and more) - but the lag remains. It's not just the mouse, even text inputs have a slight delay to them between whatever the foreground and whatever background character you're using. It seems very "deep" and almost hardware related to me, only because of all the things I've tried, none of them have made a lick of difference. So odd! Anyone else got ideas or any other off the wall theories?

Thanks as always.

Hmmm, I tried installing ISBoxer onto another laptop and runninng 2 D3 instances there, and saw the same "mouse lag". However, perhaps I am overstating what I'm seeing and this slight laginess isn't abnormal? Here's a phone video of what I'm talking about - you can see that the foreground pointer (top centre - large) moves slightly more quickly/precisely than the background pointer (on the bottom left - small).

Thoughts? Look normal to you? Thank you.
