I'm dual booting Windows 7 x64 and Ubuntu 13.04 x64 and have been faced with a very unplayable WOT with only 3-5FPS. I've also clean installed Linux Mint and Ubuntu 12.10 just to see if it Ubuntu 13.04 was the problem. It ran dog slow in all three distros. I also have the latest video card drivers installed(Catalyst 13.4). I've used the latest version of Playonlinux and Wine. I even tried the 1.5.??? World of Tanks version of Wine.

I also found a command that forces the game to run only on one core of the CPU. It crashed by system hard.

My machine specs..

Intel® Core™ i3-2120 CPU @ 3.30GHz × 4
Gigabyte GA-Z68A-D3H-B3 mobo
4GB of Ram
AMD Radeon HD 6870

I have no other issues with Ubuntu. It runs like a champ.

Turn off GLSL for the ATI drivers.

PlayOnLinux -> Configure -> select virtual drive -> Display tab -> disable GLSL support

See if that helps.

Thanks DJYoshaBYD. That did the trick and made the game playable now on low graphics setting. I bumped up the graphics to high and the game went very dark and unplayable. Switched it back to low and restarted the game and it's playable with higher 30 FPS.

Any idea why the graphics would go black?

ATI cards dont play well with linux in general, unfortunately. Thats why I rock Nvidia.

Yes. It'sproblems is because Mesa drivers misses an extension that due to US patent restrictions can not be included with the MESA driver. So what you have to do is install a library called "libtxc_dxtn"

Hi guys,

I have similar problem... ~10fps... (few months ago was better - I have no idea what changed...)
My specyfications:
Intel® Core™ i7-2630QM CPU @ 2.00GHz × 8
8GB of RAM
GeForce GT540M

I am running Ubuntu 13.04 with Playonlinux 4.2.1, wine 1.6-rc5
I have libtxc_dxtn and have disable GLSL support...
Any ideas why I still have 10fps? I tried bumblebee and pirus - without any improvement..
Thanks.

What gfx drivers do you have installed?

I installed "libtxc_dxtn". No change after rebooting. FWIW, I went to Mint 15 hoping that would fix the issue.

I have nvidia-313, but I had nvidia-304 (current) and was the same...

but in Additional Drivers window I do not have any... which is little bit strange

So, delete all of the nvidia drivers that you installed through Additional Drivers or your package manager, and install the newest drivers, by hand, from nvidia. You may not have the 32 bit libraries installed. Installing the newest drivers from Nvidia's site by hand will install these for you.

Is there really a difference when you install newest drivers from nvidia web page comparing to instaling the same drivers from package repository?
I have installed with package rep. nvidia-325 and next day I had like 30-40fps - which was great! But another day it droped to 10fps... I have not installed or change anything in my configuration and I tried different internet connections...
I was also trying optirun or primus (vblank_mode=0 primusrun playonlinux) nothing helps... I have no idea why one day I had 40fps and next one I had 10fps...

This is my output from terminal:

The PoL's "Video driver" component detects the Intel video card first, so that's what is written into the Wine registry.
In the development version of PoL the same component asks which card you want to pick, maybe that will help?
See on the download page how to get the development version.

Thanks,
I tried with dev version and got this:

WARNING. Please use POL_SetupWindow_Init first.


Mmmh I don't get those warnings. And I suppose this is the only case when POL_SetupWindow_menu can return "False", breaking the remaining code logic...
Weird.

Am I right that those messages come from your attempt to install the "Video Driver" component from the "Install components" tab?

Edited by petch

Hmm I do not understand... I don't try to intall "Video Driver" component.
What is "Iinstall components" tab?

Ah, ok found the culpit, that's a debugging feature that calls the function to detect the video cards available... From a place I didn't expect, when the interface window is not open, hence the warning. I Will have to fix this case.
It was never detected for updating the registry, so it's normal my change had no effect on the game.
You can still give it a try, but now I doubt it'll make a difference:
Configure button > (Select world of tanks virtual drive) > Install components tab > Video Driver > Install button

nope... no difference... :(
