AH, that might explain it, though. The 750m is not a performance card...basically the low end Nvidia mulitmedia card, why ever they even made it, I don't know. It's data bandwidth is a 10th of the 900 series, for example, making it really rough on something like Verve or even games.
I'm afraid it simply can't quite handle that.
I don't know what else to tell you, as sorry as I am about that.

...Geforce GTX950M is supposedly working fine!
I wonder, if somebody else on the forum has any experiences with laptop graphics to make a good suggestion for an alternative? It's definitely worth it to scour the graphics card thread on here:
