Everyone with a MOBILE card using 3Dmark05 read this!

Hi,

I wanted to tell you about a little glitch with drivers/3dmark05 that took me a long time to figure out. This may just be with Omega drivers, but I have seen it in Omegas 6.3 and 6.7 (my last 2 sets).

If you have a mobile ATI card, you may be aware of the powerplay option in the ATI control panel. There you have 3 sliders for when powerplay IS ENABLED, for AC, battery, and low battery. There are 3 options for each, "optimal battery life", "balanced", and "optimal performance".

You would expect that no matter what settings you have for the above, if you have powerplay DISABLED, your score in 3Dmark is the same. IT'S NOT!

Even if you have powerplay disabled (no checkmark), but if even one of those sliders is at anything BUT optimal performance, 3Dmark will give a lower score. I don't know how it does this. Clocks are still what they should be with powerplay disabled, so it does some kind of weird half-powerplay mode.

I don't believe this performance issue also happens in games, so feel free to leave the sliders at whatever you wish except for when using 3Dmark05.

Just wanted to warn you guys.

Bump. I'm wondering now if the sliders also affect in-game performance...

First of all, can anyone confirm the above with their system?
