ATI 8.44.3 - OpenGL Performance issues ??
I run Fedora 8 (32-bit) on a Fujitsu Siemens Amilo M1425 Laptop which uses an ATI Mobility Radeon 9700 with a dedicated graphics memory of 128 MB.
After upgrading to the AMD ATI Proprietary linux driver 8.44.3 (Catalyst 7.12), I have found that there seems to be a problem with OpenGL performance.
Hardware rendering functions well, and I get frame rates of over 3000 with "glxgears", but when I use the OpenGL select mode (Render mode GL_SELECT), and then repeatedly call the "glLoadName(...)" function while generating a mesh, the entire system freezes up with the processor racing to 100% load with even relatively small meshes...
I have not had this issue with earlier versions of the driver....in-fact, this particular scenario used to be faster on the ATI laptop, than on desktops running nVidia Graphics cards.
Is anyone aware of such performance issues with the proprietary drivers?? And would anyone have any suggestions for work-arounds ?
Have a nice day!
