Do not update your NVIDIA drivers to 344.75 driver.

I’m always interested in your reports regarding GPU drivers, so if anyone is having problems, please reply here.

I have an nVidia 520 GT here and 344.75 works just fine (had Cubase running in cycle on a mid-sized mixing project for over 5 hours now). But different GPUs might behave differently.

Thank you all and have a nice week-end.
