[Guide] Decrease CPU & GPU usage while botting [D3Prefs.txt]

Hello.
First of all, this isn't new at all. I haven't seen a "guide" posted here about it though. There might be one, I don't know. If it is, feel free to delete this thread or whatever.

1) Download View attachment D3Prefs.txt (Updated 5/12/12 22:31)
2) Navigate to: C:\Users\%username%\Documents\Diablo III\
3) Replace the D3Prefs.txt with the one you just downloaded
4) Start Diablo III
5) Enjoy.

My results with the tweaked D3Prefs:
Before (%) - After (%)
CPU: 85-95 - 35-40
GPU: 50-60 - 25-30

The graphics might not be the best, but who cares? It's not like you're playing anyway...




If this helped you out, feel free to +rep me and like this post, thanks!

Credits to Mileno @ OC for posting the D3Prefs.
I did edit it a little for better performance though.​

 

88 downloads on the D3Prefs, 1 like and not a single comment?
Awesome.

 

Hey man, there is a thread about bot crashing in which they tell you to modify the D3Prefs.txt file. It is nice to just be able to download and replace it though, so thank you. If I hadn't already followed the other instructions on it I would be downloading and using this.

 

set DisplayModeBitDepth to "16". rest looks just fine. ty

 

doesnt really help.

 

Spork, it should definitely help. You need to ensure that the line that Stahlwart mentioned is changed as he has said in his post. If you do this, and shrink your windows to their smallest size possible (800x600) then your CPU/GPU usage should go way down. The game looks like complete ass, but thats why it runs so easily.

 

Why does that surprise you with the community we have? : - )

Anyways, I've downloaded it and I'll give it a shot, cheers.

 

I'll try with that and see if there's any difference on my side.
If it is, I'll update the attachment in the first post.
Thank you.

 

It definitely decreases load on GPU. It changes the color from 32 bits to 16 bits. Looks like hell but runs like a champ.

 

Can Blizzard check your D3Prefs file?

 

I'm not sure if Blizzard tracks user hardware and software configurations. Some games do so they know how the game runs on different settings and hardware setups.
However, even if they can, they cannot do anything to you for playing with crappy graphics.

 

i did what giles posted in the support forum. working fine

 

Interesting, will be checking this out sometime soon for sure! thanks

 

your D3Prefs.txt starts game in FULLSCREEN.. maybe edit that..

Change it to window mode, 800x600 and change also settings.

 

Any reason these settings include high physics, shadows on, and a few other options that can be turned down \ off?

I used your prefs and changed to windowed, 16 bit, no shadows, low physics, etc on my own and had a giant increase in efficiency, but I am curious is there was a reason they were left on.

 

Updated the file attached in the first post.

 

Btw, if you are using this for a computer with an unsupported video card, you need to run Diablo once with these prefs, then go edit your hardware class back to 1.

I couldn't figure out why this wouldn't start on my laptop, then I realized it had moved my class back to 0. I think it did that when it edited my resolution.

 

Guess it's time to dust of my old laptop then :>
Didn't think of that, thanks

 

I am using Yar , but it doesnt seem to resize ur configuration to smaller windows . as supposed to my normal config
