My Nvidia Geforce GT630 doesn't show up when I go to graphics config

[Titannous]

I don't know a lot, but if I was worried my video card wasn't working properly with the application I would download GPU-Z and check the sensor tab while running dolphin and make sure that it is under a decent load. I would think at least 30-40% usage even with a CPU bottleneck, but that's just my guess. Someone correct me if I am wrong.
