Hi I am also having this large disparity betw windows/POL performance
My config is ofc quite a bit older than the above one

P4 3.4 Ghz,
3GB ram,
NVidia 9500GT
OS - Windows 7 / Linux Mint 13

On Windows
In most cases ~40

On Linux
town 15-20
Fight ~5

I havent tried windowed. I dont use compiz (i use the default marco, metacity's lesser known cousin)
Is this disparity expected, esp for my PC or is there a way to get D3 playable in linux?

it seems to be a problem with multicore CPUs, try to bind Diablo 3 on 1 or 2 Cores and it runs much smoother

AMD FX 8150
NVIDIA GTX 560 TI Golden Sample
8GB 1600MHz RAM

without setting CPU affinity 5-20 FPS

With setting affinity ca. 50 FPS

I added the binding to one core to the script:

POL_Shortcut_InsertBeforeWine "Diablo III" 'taskset -pc 0 $$'

I wanted to mention that *undoing* the 'taskset' command fixed this issue for me, so apparently YMMV. I'm running the following:

AMD Phenom(tm) 9150e Quad-Core Processor
GeForce 9400 GT (256MB)
4GB 400MHz RAM

Without setting CPU affinity, I get 20-25 FPT, with it, I get an unplayable game whenever facing more than one or two enemies.

So I simply commented out the 'taskset' line in ~/.PlayOnLinux/shortcuts/Diablo III

Wow, and both with nVidia cards, this is crazy...
So now what should we do?

Removing the affinity also works for me, I think that between August and now that change might be no longer needed due to some patch to the NVIDIA drivers, Diablo III or wine. But YMMV, so check up with a few more people on this...

Blizzard should Perm Ban you for playing in linux, just like did to me. Just saying.

Hello,

I'm using:
Processor: AMD Phenom II X4 945 @ 3.00GHz (4 Cores),
Motherboard: ASUS M4N78 PRO,
Chipset: NVIDIA MCP78S,
Memory: 4096MB,
Graphics: NVIDIA GeForce 9500 GT 512MB (550/400MHz).

In the windows and with 1440x900 the game works normal (20~23).
In opensuse 12.2, the game is playable in 1440x900 (12~15 FPS, slightly slower compared to windows), but in sewer scenarios ( with water and fogs) the FPS is the worst (less than 8 FPS).
I changed the screen to 800x600 the game became playable again (~20 FPS in the water-fog ).

I think my nvidia card driver is ok, but the game is in the limit with my 9500GT. Therefore, there is no way to improve the configuration to achieve a very fast and playable game with this nvidia card.

I am a complete beginner to linux and playonlinux. Don't know coding, compiling, scripting, etc. And i have a small fix

My spec:

Zorin OS 9

Intel Core2Duo E7500 2.93 Ghz

Gigabyte EP45-DS3P

2gb Kingston 1066 CL7 Dual Channel

Gigabyte Nvidia 9800GT 512 mb

 

FPS in town (before fix): 22-30

FPS in dungeon/sewers (before fix): 60-70

-

FPS in town (after fix): 30-38

Wine version: 1.7.15

Didn't test in dungeons / sewers yet

-

I saw a widely used fix for fps issues that helped me.

I hope this helps:

Wine -> Browse C: drive -> users -> (click on your user, not on "Public") -> My Documents -> Diablo III -> open "D3Prefs.txt" and change the following:

DisableTrilinearFiltering "0" -> set it to -> DisableTrilinearFiltering "1"

HardwareClass "1"

 

Forgot to mention that i have all my settings in-game to low (except density which is on medium or something), fullscreen and 1920x1080 rezolution.

Thanks!
