Hi there,
I found out that selecting the preferred GPU for dexpot as the discrete NVS5400M had a huge positive performance impact on my laptop. By default, the nvidia drivers selects the HD3000 for dexpot, I went in the nvidia control panel to force it to the other card.
T430 i5 with HD3000 and NVS 5400M (1GB VRAM) (known as optimus graphics)
I hope it can help!
