[SOLVED] Weird graphics on freeorion with ATI card

[Rydra]

Hi there,

I have freeorion installed on 2 PCs, laptop and desktop. On laptop (with Intel card) it works and shows fine. On the desktop, with an ATI card, mouse and fleet icons are shown weirdly. I attach screenshots of the issue.

Is there any known issue regarding freeorion and ATI cards?

greetings,

Rydra

I've never seen rendering issues like that before (though there have been various others)... Make sure you have updated video drivers.

As an ATI card owner I'm not aware of that issue. Do you use fglrx or the open source ati driver?

I'm using fglrx (extract from /etc/X11/xorg.conf)

Code: Select all

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        BusID       "PCI:1:0:0"
EndSection

Also my ATI card use legacy drivers on ubuntu as it is a Radeon HD 4350 (I think those are not updated anymore, they are ubuntu-amd-catalyst-install and fglrx-amdcccle-legacy packages, which they are installed on my system)

If you're using the legacy fglrx driver I would suggest to move to the open source drivers. I know when I used the fglrx (a long long time ago…) issues like image corruption as the one in the screenshot were daily business (alongside with the biweekly spontaneous X11 hangups and crashes ;) ).

I uninstalled fglrx and installed the OpenSource ATI drivers and now graphics are shown fine! The downside is that performance of demanding 3D like Amnesia or any other FPS decreased dramatically, but ohhh well... I'll have to balance those situations.

The steps I followed to uninstall and reinstall the ATI drivers are found here: http://wiki.cchtml.com/index.php/Ubuntu ... st.2Ffglrx

I mark this post as solved.

PD: Btw, is it normal that the full research tree and the game in general consumes so much CPU? It's always at 100% and I don't think it requires so much 3D rendering... and graphics are not smooth on ATI OS drivers

You can limit the FPS in the video options tab. It doesn't actually work correctly to produce the requested FPS, but setting a limit should reduce CPU use doing unnecessary rendering.

Limit was already enabled, though I'm already experiencing 20 FPS with ATI opensource drivers(though corrupted graphics, fglrx provided more performance up to those 60 FPS). I think it is a graphics card issue and nothing can be done about that.

I've just fixed this issue by updating the proprietary driver to version 1:13.11~betav9.4-1 from testing, on Debian wheezy.
