Re: R400/T400/T500/W500: Switchable graphics issues with Win 7

2010-11-29, 14:01 PM

I have reinstalled my t500 on a new HDD (Momentus XT hybrid SSD...which seems to be running quite well BTW!)

 

Switchable graphics installed fine.  ran all updates. Installed the latest switchable graphics drvers and do not seem to see any real issues yet.

 

I complained in my previous post about the switchable modes not switching automatically.    I have read on the Lenovo site about that particular feature being disabled intentionally. 

 

But I have to wonder, modes did switch automatically using the ATI drivers v 10.8.(I did not try any of the newer ones)  They seemed to work well.   (perhaps, I have not pushed them as hard as some of you out there...I'm not a big gamer)

 

Has anyoneone who installed them had a problems with the ATI drivers?  What is so specific (or better) about lenovos implementation of those drivers?

 

Can anyone (or Mark) offer some input?   

 

Thanks

ATI's drivers never explicitly provided support for ATI/Intel switchable graphics (not even in 10.10).

The issue with ATI 10.8 or 10.9 was that if you ran the ATI version only, you wouldn't actually power off the discrete GPU leading to terrible battery life and lots of heat (62C idling).
