Very poor performance under Linux

Not sure if this qualifies as a bug, so I'm posting in a new thread...

Today I tried installing Dom3 on my laptop, and since the OS I use 99% of the time with it is Linux, I first installed on Linux.

What I found out was that the graphics were extremely slow - like 1.4 FPS on the lowest setting. And I'm running up to date Linux drivers from the manufacturer (ATI, I believe - I didn't check, but I seem to remember that).

When I switched to Windows (XP), the game ran perfectly fine and fluid.

Did anyone else notice a performance gap between the OSes? (I still have to check on my home desktop, see if it's similar) With Dom2, I never had the same problem - indeed I almost only played Dom2 under Linux.

I just checked what it does under Linux on my home desktop, and the performance is almost as poor - like 2 FPS on lowest setting. Again, the same machine runs the game just fine under Windows (XP Home).

Also, I experienced something strange with the laptop: the power was off, and suddenly the graphic battles showed the same kind of low FPS that the Linux version did. Could there be some setting of the graphics card that says it should run on some low-consumption mode, and that would be how it typically runs on Linux?

Could it be a driver problem ?
I always have problem between Dominion 2 and the ATI card of my previous machines on Linux and Windows 2000.

The desktop is Nvidia, and shows the same kind of problem. And the laptop under Windows works fine when its power adaptor is plugged in.

Sounds like a problem with your video drivers, really. Do glxgears work?

I have the same problem with my ATI graphics, see Post#455756 for a more detailed description.

In my case, glxgears and other games work fine, but DomIII somehow still uses the wrong software libraries (MESA) and hence is real slow. So it is either the fault of the ATI drivers or the distribution. What Linux distribution are you using? And please post if you find a solution (I have given up for now)!

Interestingly, Dom2 does still runs very fast...

glxgears reports between 200 and 300 FPS, depending on whether I'm moving other windows apparently. Works perfectly fine, IMHO.

I haven't tried running Dom2 on this machine (and I lent my copy to a friend, in the not-so-secret hope of converting him into a possible opponent), but it always ran perfectly fine on all machines I installed it on, including a previous laptop.

I'm not sure which distribution I'm running, as it was installed by the sysadmin at work, but it's some version of Red Hat.
