Black textures and artefacts on faces

Could you post a dxdiag report? The dxdiag report contains valuable diagnostic information about your computer hardware. Here are instructions in how to run dxdiag and save it as a text file: https://help.ea.com/en-us/help/pc/how-to-gather-dxdiag-information/

Here it is ! 🙂

I see your laptop has both onboard graphics (Intel HD 4000) and a dedicated graphics chipset (AMD Radeon HD 7670M). The AMD Radeon is the better of the two. I suspect that the game doesn't automatically switch on the AMD Radeon. This could happen, for instance, if you're running your laptop on battery power or if the laptop is otherwise configured to use little power.

If you were running on battery power before and plugging in the adapter fixes the issue, then you're done. Otherwise, keep reading.

The graphics drivers for your AMD Radeon are outdated (from 2012). The latest drivers version for your GPU is a beta driver from 2016, which you can download here: http://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows%207%20-%2064

I recommend downloading and installing Crimson Edition 16.2.1 Beta.

Once that's all done, I recommend checking out the following page which explains how to make sure the game runs in high performance mode: https://community.amd.com/docs/DOC-1581

Hello ! 

Thanks for the links. I already use the different powers settings, and I always play with adapter plugged in and high performance, but, yes, I haven't check the driver updates. I'm happy to be able to configure my graphic chipset with this new driver. 

Unfortunately, it doesn't change anything in Mass Effect 2...

Do you use any mods?

Make sure Origin is closed

Go to: "Documents\Bioware\Mass Effect 2\BIOGame\Config". 

Rename the "GamerSettings.ini" to "old_GamerSettings.ini" > Start Origin > Test the game.
