Default Graphic problems with Catalyst 3.6 and OpenGL (Jedi Knight II)

Hi NG!

I just dug up Jedi Knight II and started playing it. This is so far my first
OpenGL game for a while. The last time I played it I had a Geforce 4. Now I
own a Radeon 9700 Pro and the game gives me some weird problems with the
character shadows. Not the shadows on the ground but the shadow effects on
the bodies. It's hard to explain but some polygons that are in the shadow
are bright and some polygons in the light are dark. It looks quite
irritating.
Has anyone a clue what can be done? The latest patch is already installed.
Is this a common OpenGL problem?

Thanks for your help!
Chris

I found that exact problem with Star Trek : Elite Force 2 as well. If shadows
are on, the shadow effects on the faces are incorrect. It looks like the
polygons are getting lit wrong, causing weird black triangles to travel where
the shadow is supposed to be.

Guess it's only with OpenGL games this happens..

I'm using Omega 3.6 cats btw with a 9700 pro.

Good to be not alone, but this sucks! If it even happens with new games and
also with the Omega drivers is this a major ATI OpenGL problem or what?

My Jedi K 2 works with Omega's modified version of 3.6

There an option in the game menu for different "types" of shadows, I seem to
remember one looking very much worse than the other.

Yes, there are three types (None, Simple and Volumetric). It's the
volumetric one that makes the problems. I switched back to simple shadows
and now it is at least playable but it looks really bad for todays
standards.
Has anyone got the volumetric shadows in JK2 working with a Radeon and
Catalyst?

There is a thread on Driverheaven that has pictures of my issue with Star Trek
Elite Force 2. I think it's the same problem you are discribing with Jedi II.

I just checked. There's a tad bit of misdirection in some of the shadows.
But, not enough to really annoy me It seemed very minimal. I'm using
the 3.6 Cat's on a 9700np.


Well, of course that a very personal opinion but it is annoying enough for
me ;-) Especially in third person (light saber) mode the shadows on Kyle
look awfull. Also shadows of enemies can be seen through walls or walkways
(that's almost a way of cheating) so I had to switch to simple shadows.
Let's wait for Cat 3.7 or higher. The only fear I have is that the problem
will also exist in JK3 which is comming soon :-(

Yes, that's exactly my problem. I hope there will be a fix for it soon. I
want to play JK3 WITH volumetric shadows!
