I have a rMBP and I just installed Parallels the other night and was very excited to play Saints Row 3 that I bought from the steam summer sale. I try to play it and it gives me an error "Failed to create graphics device". I've looked online for this problem and a lot of people have had this problem and they just upgraded there graphics card. I looked up the updates for NVIDIA 650M cards and found a beta update and I tried to install it on parallels, but it gave me an error and wouldn't let me upgrade. Anyone know what I should do?
