CRT-O.

I installed turbojpeg. Still jpeg compression gives choppy performance. With yuv 
compression, and VGL_READBACK unset, I got decent performance (seems faster than 
intel card for 3D performance, i.e. 3D buildings in Google Earth)

Hi..

It seems that it depend on the application, which mode gives the most 
performance..

But thanks for your feedback.. I will add an option in the script...

Are you running with CRT-0 og DFP-0 in the configuration???

You're right. optirun32 Google-earth worked.

Your install scripts use VGL_COMPRESS=jpeg , wasn't yuv supposed to be faster. 
With jpeg compression, google earth was a lot slower (even much slower than on 
intel card). I changed compression to yuv and performance is much better.But 
still feels slower than intel card. I will look at the logs etc and send more 
details soon. I will  install turbojpeg package to see if it makes any 
difference.

Hi..

Thanks for your feedback.. try running optirun32 on google-earth instead.. might 
be an 32-bit application...

I installed your package and was able to run "optirun64 glxgears" on Dell XPS 15 

(L502x). It gives me about 1600 fps. Nice!

But "optirun64 google-earth" returns following error:


[VGL] WARNING: VirtualGL attempted and failed to obtain a Pbuffer-enabled
[VGL]    24-bit visual on the 3D X server :1.  If the application
[VGL]    subsequently fails, then make sure that the 3D X server is configured

Of course,  thanks a lot!

Sunil

Hi all...

The subject says the most:

Prime-NG v.2.0 released.. now with automated installer and 3D support on both 
Intel and nVidia..

I finally got it working, with some help from Pigeon... so thanks to him also...

Hope to get some feedback so that I may improve the installer... I have tested 
it as good as I feel I can.. but the still might be some bugs..
