Since you have a laptop, use BOTH the intel and nvidia graphic drivers as supplied by the laptop manufacturer.

Hello NinjaUmbra, 

 

Thank you for posting on the Intel® communities.   

 

I can see based on the report you provided that you are using the Windows* 10 Insider Preview Build 21313; for these Operating Systems (OS) builds, the driver most likely comes from Microsoft's side through Windows updates. Also, since you are part of the insider group, any feedback or questions should go directly to Microsoft* as this is their request. 


On the other hand, the recommendations provided by the community are correct; you should be using the drivers provided by your OEM. Installing Intel generic drivers will overwrite your OEM customized driver. OEM drivers are handpicked and include customized features and solutions to platform-specific issues.  

 

Regards,
