Youtube fullscreen - comp lags like crazy

[electricFuzz]

I just realized that I can't watch vids on fullscreen in my comp, only tried youtube so far. The sound runs smoothly but the picture lags severely.

So far I only tried to unable desktop effects, no difference...

Software
Firefox 5.0
Flash 10.3 (32bit)

Graphic card
ATI radeon 57XX something...

I've seen post here and there but I haven't really got an idea of what's gnarly. Any pointers or help appreciated.

You might need to install the proprietary drivers for your video card if you haven't done so already. Doing so should give you the best results for graphics intensive tasks. I don't run openSuse, so don't know if they have any easy methods of installing them, or not. If they don't, you can probably download the drivers directly from either the video card maker's website, or the ATI website, and then install them.

Well... at least I think I have the proper graphic driver installed. If I bash it out I get this:

01:00.0 VGA compatible controller: ATI Technologies Inc Broadway PRO [Mobility Radeon HD 5800 Series] (prog-if 00 [VGA controller])
        Subsystem: Hewlett-Packard Company Device 1522

        I/O ports at 4000 [size=256]

        Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?>
        Kernel driver in use: fglrx_pci

I got the driver from the ATI site. Honestly, the out put is a little bit like Arabic language to me. However, the card is supposed to be quite powerful. Something like 4 G memory with 1 G designated etc...
