Vegas pro 10 not starting on Nvidia geforce GT 650M
I got this new laptop about a month ago from novatech and it has: Intel core i7 3610QM 8GB RAM 1TB HDD (idk what RPM it is) Nvidia Geforce GT 650M
But for some reason Vegas isn't starting on my 650M but starting on Intel HD 4000 instead This is very annoying as it takes ages to render even in AVC, it almost renders in real time because i just rendered a 720p video which is 9.5 minutes long and it took 10 minutes. My friend has a gtx 580 and he can render extremely fast, so i got a 650 because i thought it would be almost as fast.
I've already set my prefered GPU to the 650m but still it uses the HD 4000, and Ive even tried setting the 650 to launch only with vegas but still it runs with the 650M.
