"Call stack" when starting the game

[fabio]

Whenever I start the game I get the following "Call stack":

Pressing 'C' let however the game start.

I am using r7139 on a Ubuntu karmic. Let me know if I should provide more infos.

Greetings! Looks like it's just warning that your graphics card is a bit old. If possible, we strongly recommend running on at least GF3-class hardware.

[Philip Taylor]

Alternatively, it might be that your graphics card is fast enough but you don't have ​S3TC support enabled - you should be able to run driconf and enable the "enable S3TC texture compression" option, or install libtxc_dxtn.

[fabio]

I have an Intel i945G/GZ card. The driconf trick worked, thanks.

But what's the mean of the "Call stack"? What limitations the game will have without S3TC support? Why not letting the game start without the "Call stack" or simply make the game quit? Or is the call stack only printed in debug mode?

(sorry for the late reply, but I though that having defined a mail address I would have get notification of reply but that didn't work)

[Philip Taylor]

Without S3TC support, the game will uncompress all of its textures before using them, which causes it to use between 4 and 8 times as much memory (and video memory) and will probably slow it down a lot.

We definitely should handle this situation more gracefully - I've filed #313 for that. At the moment it's just using the standard error reporting system, which does all the irrelevant call stack stuff.

(Hmm, email notifications really ought to work - I got one for your comment. Do you see one for this comment? (Might it get marked as spam or something?))

[fabio]

Thanks for the reply.

(and yes, I got the notification for this reply)
