I have 10.5.2 installed on my hp dv6521 with geforce 8400 M GS (Full QE/CI).

OpenGL Extension Viewer tests shows that card is 5 times slower on Leopard than on Vista. (Mean values during the tests are around 120, but on Vista around 600)

Is there any explanation, tweak or anything else?

 

P.S I had some improvement when i sleep the computer and run the test again but still not close to the performance in windows!?

hello ,turn off the "beam sync" option,and try again.

easy way :use a small tool from xcode package,it's a long time so i forgot the name,sorry.

or you may try this code in your terminal window:

sudo -s

 

[type your password]

 

chmod -R 755 beamsync

 

chown -R root:wheel beamsync

 

./beamsync -d

 

reboot your box,then you have it .
