Hello together, i have a working eGPU setup now with the help of you in this forum and especially with help of Tech Inferno Fan ... so thx for it. Last little problem i have is that after chainloading from Setup 1.x software into Windows 8 (8.1) with the deactivated dGPU my Windows have to (re)install the nVIDIA drivers every time and wants another reboot. After that all is fine in the device manager until i do a reboot without the eGPU and work with the regular rig setup. Nex time i start Windows with the eGPU ... "you have to reboot the system to finish ....". Sombody knows what to do and can help me with this? My rig is a Lenovo T530 with HD4000 + nVIDIA NVS5400 + eGPU nVIDIA 760. Is'nt it possible to run the dGPU with the Quadro Optimus drivers and the eGPU with the regular Geforce driver like i do? Do i have to install one driver for both cards? Thanks & greets from Dresden
