Crashing issues with dual graphics
So I've been trying to run Mass Effect 3 on my Lenovo Ultrabook U400. It uses 2 graphics cards working together, the AMD Radeon HD 6470m and the Intel HD graphics family. While this effectively means...

Have you switched to the Radeon GPU before starting ME3? The two GPUs won't work at the same time. The 6470m should be able to handle ME3 just fine.
Keep in mind that usually when running on battery the Intel GPU is selected.
I've tried switching to "high performance", in the radeon catalyst control center, if thats what you mean. For some reason the game actually runs worse then.
- If you right-click on the Desktop you should be able to select the switchable graphics. But if you see the Catalyst Control Center it means the Radeon is active anyway. Are you plugged in or playing in battery mode? You could also try to switch the energy settings of windows to high performance. Have you measured the temperature of the GPU for instance with MSI Afterburner? Maybe it gets too hot and clocks down.
[Edit]Also, if you are running a very high resolution like 1920*1080 it might be too much for the GPU. The slower performance when in high performance mode might indicate a heat problem where the GPU clocks down to prevent overheating, which may also be a possible reason for the crashes- Approved
If i right click on the desktop I have two graphics related options, the first is the control center, and the second is switchable graphics. In switchable graphics I can choose between power save mode and high preformance. I tried setting ME3 to high preformance, but that causes the game to run very poorly (awful frame rate and very laggy). It runs fine if I set it to power save, but then I run into crashing issues every 20 Min or so. I have attempted to find upgraded drivers because the built in ones are from 2011, but because Lenovo has special drivers for the lenovo ideabook U400 there don't appear to be any more recent drivers. also it is running at 1366x768 and I am plugged in whenever I am playing.

also i used MSI afterburner to record my temperature druing a play session, my max temperature was 77c, This was when ME3 was set to power save mode, but I did notice that it quickly rose to 77 and then stayed there, so there was no spike when the crash happens.
