Hello all!
I have two PC's with ATI Radeon cards… Radeon HD 4870x2 (Windows Vista x64) and Radeon HD 3650 AGP (Windows XP Pro SP3/Windows 7 RC). Both of them had seen the same problem. When the polygons in the model became more than 2k selection of components becomes very slow. At the same time on computers with geforce cards all works excellent. After week of finding a solution to this problem, the answer I did not find one.
However, the decision was found, and I want to share it with all who have a similar problem arose.
Here is my way:
1) Go to C:\Windows and open file atiogl.xml with your favrite text editor.
2) Find this peace of code:

<!– Houdini –>
<ProfileHoudini>
<OpenGLCaps>0x00008008</OpenGLCaps>
<OpenGLCapsEx>0x00000000</OpenGLCapsEx>
</ProfileHoudini>


3) Replace this lines with code from some other profile. I'm use Softimage XSI profile and all works perfect:

<!– Houdini –>
<ProfileHoudini>
<OpenGLCaps>0x20008000</OpenGLCaps>
<OpenGLCapsEx>0x00000400</OpenGLCapsEx>
</ProfileHoudini>



I hope this information will be useful

Thanks a lot! A problem where I found the solution at first go this time. Had the same issue with my fireGL. But I only deleted the last 8 in OpenGLCaps, like it is in the LigthWave-3D profile.

Selection works fine with this trick. Unfortunately I can't move objects properly in their z-axis anymore when changing the xml file.

Anyone else with this problem?

hoho…

I'm sorry guys…
z-axis handle really does not work with this trick…
I noticed it only after reading schyzomaniac post.

But perhaps we will solve this problem, if you try to use the following values:

<ProfileHoudini>
<OpenGLCaps>0x000083F4</OpenGLCaps>
<OpenGLCapsEx>0x00000000</OpenGLCapsEx>
</ProfileHoudini>


With this values selection and handles works fine on my Radeon HD 3650 AGP (Win XP SP3 & ATI Catalyst 9.3 agp fix).
Tomorrow I will check this trick on my Radeon HD 4870x2 (Vista x64).

P.S. Please specify the names of models for your video cards.

Good luck

Hey. That seems to work fine. Where did you get the lucky numbes from? Which profile?
I'm having a HD2600 Radeaon in my laptop by the way. Never ever ATI again after this one. I don't know how they can screw up their drivers so badly.
Anyway - enough ranting.
Thanks for the tip! It seems to work now.


Daniel

checked on Radeon HD 4870x2 (Vista x64)
All works perfect!

I don't use any existing profile for this values. I'm find it by some calculations.

P.S. Don't forget to fix atiogl.xml after new drivers installation…

You are a genius.

Just tried it with a lower profile ATI HD 4830, and it didn´t solve the problem… maybe you know other magical numbers?

<OpenGLCaps>0x000083F4</OpenGLCaps>
<OpenGLCapsEx>0x00000000</OpenGLCapsEx>

ati hd 5870 v2

also had to use asus drivers.

Anyone else have occasional crashing when trying to do something in Houdini's interface? I can't recall what I was doing, but it is getting on my nerves.

I just updated my Win7 laptop with 11.2 (latest) drivers and made the fix to the reversed normals that was told to me on the Houdini Mailing List and the occasional crashing is bugging me.

Cheers,
Craig

Hi Craig,

I was getting a number of crashes on a few machines with the Catalyst 11.2 driver and after reinstalling with the Catalyst 10.9 driver, the systems were stable so far.

Hope this helps.

Cheers,

I was getting crashes before with 10.10 so I was hoping 11.2 would fix it.

Maybe I should go back to 10.9… :?

Thank you I can work on Apprentice at home. No more loud students in my ears all day!

is still slow , is there a fix for ati 5850?
