Can't select items and the framerate is slow for ME3

The inability to activate objects and doors is linked to low framerates. Fix the framerate, and you can open doors.

To check your hardware, on your keyboard press the windows logo + R. This will open a dialog box. In this dialog box, type dxdiag and then press enter. At least, that worked on previous versions of Windows. In any case, find a program called dxdiag and open it.

You'll see most of your relevant hardware specs on the main page and the graphics hardware is on the display tab.

At this moment, it seems to me the most logical conclusion is that your PC isn't made for gaming and is too far below the system requirements to be playable. When you come back and post your hardware specifications, we might be able to narrow it down a little.

Also please specify if you have a laptop or desktop PC.

It's an Acer Laptop, not totally sure what model. I also didn't know how much or how little you needed so I just copied and pasted. I've not had any problems with my high graphic mods for minecraft or when I play League of Legends or a few other HQ graphic games. I don't know why it wouldn't be alright for mass Effect when I'm running it low quality.

Ugh...
Thanks. I was told this computer HAD an AMD card in it is why I purchased it in the first place.
That was very helpful, thank you.

If there's an AMD sticker on the laptop, you likely have an AMD processor. That was their main business before they took over Ati.

It may also be possible that there is indeed an AMD GPU in there but that the PC is using the integrated graphics instead. If the laptop came with an AMD driver CD, install it.
