GeForce MX130: open source or proprietary driver?

[printf]

Up until now i only had ATI/AMD and Intel graphics cards on any of my linux machines, or if there was an NVIDIA, it was a desktop, where the driver choice didn't really matter.
I have a DELL Latitude 5591 with an GeForce MX130.
So far the integrated Intel card has been set up, 3D works (tested with Uniengine).
Now I am at the decision of what to use, in which combination: nouveau/proprietary? optimus/bumblebee?
I would prefer the open source route, but i read, that the card switching works only with the closed-source driver.
On my other machine with AMD, i had the script prefixed with DRI_PRIME=1, and I actually would be perfectly fine with turning on the dedicated card only when i know it will be needed, not interested at all in automatically managing workload.
Is optimus/bumblebee needed to be able to switch between the cards at all or is it useful mostly to be able to switch cards to adjust for performance requirements?
Is there a significant difference in performance and stability between the 2 drivers?

The MX130 uses a Maxwell-based GM108 chip (NV110 family). According to the feature matrix: https://nouveau.freedesktop.org/FeatureMatrix.html video decoding acceleration is not supported and power management is work in progress.

Switching between the iGPU and the dGPU might not work reliably: https://wiki.gentoo.org/wiki/Nouveau#Switching_between_Intel_GPU_and_Nouveau

So, you might try the nouveau driver and if you're not satisfied you could always switch to the proprietary nvidia driver (the only problem with the nvddia driver is you have to re-merge it after every kernel change to rebuild the nvidia modules).

I had a lot older card which was fully supported and I still wasn't happy with nouveau. The most common problem - artifacts or even unintelligible content on the screen after wake up. And it wasn't wake up from system stand by, it was wake up from just monitor standby. I didn't even test system standby, because it was a desktop computer, but I would expect even more serious problems.

thanks. will try the official driver then.
it's interesting, because at AMD, it's the open-source drivers that seemed to suite me the best.
