I currently installed Wine and I'm successfully playing Diablo III. However, when I check my FPS, it's around 40 FPS. My computer is an ASUS X550LB with 8GB of RAM and an NVidia GeForce 740M. I believe the specs are alright and should run a game like Diablo III at around 50 - 60 FPS. How do I check if my NVIDIA video card is activated?
EDIT: Whenever I run
lspci | egrep '3D|VGA'
this shows up:
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
04:00.0 3D controller: NVIDIA Corporation GK208M [GeForce GT 740M] (rev ff)
Is there anything wrong there?
