metamorphosis demo and ATI driver problems...

category: general [glöplog]
 
Hi all,

some people have noticed that our latest asd demo metamorphosis
( http://www.pouet.net/prod.php?which=50127 )
does not work with the newest ATI drivers.

After working a few days with the following good people:

Troels Østeraa
Hannes 'robotriot' Drexl
Chris 'psonice' Wood

I've found what was wrong. Apparently

glTexImage2D doesn't seem to like GL_COMPRESSED_RGB as internal format any more. Trying to do so will not give you an error or a crash straight away. If you try to use that texture (bind) it will then crash / slow down to a standstill. Weird. Any ideas ?


The new version for people with ATI problems (this one doesn't compress textures at all) is at:

oh try to use the mousewheel while you're at it too ! :-)

thx, it now works perfectly here :)

(I'm using GL_COMPRESSED_RGBA here and it works ok... you know, RGB formats are always tricky)
