About 4 months ago I bough a GTX 1050ti, yesterday my friend gifted me his RX 590 in favor of a new card he had bought. I being the ignorant man I am, plugged the RX 590 into the Top x16 PCIe Slot, and the 1050ti into the Bottom x16 PCIe slot. I then installed the Radeon Drivers for the 590 and left the Nvidia ones installed. Today I tried to use my Oculus Rift VR. It works only when plugged into the 1050ti, but I need working on the 590 because the 590 is a better card, and will run my games better. It will load on the 590 and then freeze immediately after loading the oculus software, and SteamVR does detect the headset. If anyone has any advice it would be much appreciated. Please help.
