Windows 7: Acer Laptop: Switchable Graphics using i7 & AMD Radeon

I would like to mention that I have run an OpenGL benchmark program on my system (3D Mark 11) - dynamic switching mode (since that's all I have), set to High Performance. While the results are nothing to brag about, being OpenGL didn't cause the system to crash the way it did in the video. My guess is that this is due to improved drivers.

I did see something in the first video that gives evidence to what I suspected and mentioned earlier. When using dynamic switching, setting to High Performance or Power Saving might not matter. The system appeared to use what it believed was appropriate. In the video, the performance suggested that in his test it used the Radeon GPU both times. This suggests that if the system doesn't feel it needs the Radeon, it could very well ignore the High Performance setting. If this is true, it definitely needs to have the manual control returned to the CCC.

I did this, and here is what happened on my system:

3DMark graphics benchmark program now refuses to run - it claims it can't find any DirectX 11 compatible hardware.

World of Warcraft's reported frame rate dropped from over 50 fps to under 20fps.

Fortunately I created a System Restore point just before installing it.

UPDATE: The System Restore didn't complete properly, so I did a manual Driver Roll-Back. While I was doing that, I noticed that the AMD Radeon driver had been disabled by the new Intel driver. This would strongly suggest to me that the Radeon is being used for WoW.

Yes you can read in the link that for acer there is only a way to force intel on it, not yet for amd.

Seems like HP ( I know, shocking right...) is the only one who released a bios to disable the intel card.

From what I've read, there really isn't an "intel card." What would be disabled are the graphics capabilities built into the CPU (i3, i5 or i7).

Antialising Sucks

Got the same Acer AS 7750g-9657 but everytime I put any Game with Antialising x2,x4 or x8 is like the game goes sooo slow.
So wut can be the problem here, Im driving crazy, I got another laptop ASUS with less video and all games runs great with maximun antialising.

Im start think about that the main problem is this Dynamic Switchable Graphics.
Any ideas how to improve this problem.

amd has issues with switchable graphics, opengl programs are being run by intel hd instead of the amd graphics. Hp and some other laptop manufacturers have released a new bios update, to disable the intel hd. so that your laptop will only use the amd graphics. sadly enough acer has done nothing so far it seems. (i have contacted them many times)

Anyone had any luck with this. Wish I had seen this thread first, but I also purchased a 7750g-9657, specifically for video djing. Unfortunately it will not run video on the secondary monitor correctly. My guess was because it wasnt switching to the ATI card, and was pleased to find this thread to confirm it.
