Hey there,
I resiliently bought a new laptop (Acer f5-573G-50VW) with windows 10. It has a intel i5-7200U 2.5ghz processor, a gtx 950m, 8gb ram and a ssd so everything should be good right ? Well, it’s not 
I open blender and I get 5 fps when I try to rotate around the cube. if I click on a button it takes 2 seconds to open the menu or do something. So my new PC is way slower than my old one.
Please if anyone knows something help me 
Blender Version: 2.78c
Is this computer this slow outside of Blender?
If so, it’s either a faulty/slow hard drive or bloated OS. Windows 10, is very, very bloated.
But again, 8GB of RAM and an i5 processor should be fine.
Use task manager and see if your hard drive usage is maxed.
maybe bad drivers. make sure you are using the nvidia, not the intel, also.
dont use driver auto updates.
My computer is normal outside of blender, only blender is slow.
And my hard drive and the other system components are no were near max performance
I just update my nvidia drivers. But how can I make sure blender is using them and not the intel one?
if you go into the nvidia control panel, under 3D settings, there should be a Preferred Graphics Processor. set this to High Performance Nvidia and NOT auto. if you want to save battery, then set this to Intel Integrated.
NOTE: running the Nvidia GPU from battery could perform worse than the Intel
PS: for another large performance boost, make sure shader cache is OFF and threaded optimization is OFF. setting the texture quality to High Quality will slow things a bit for games, but it will look super pretty.
This has already been discussed to death in this forum…
Make sure to download and install the latest graphics driver from the nVidia website.
Win 10’s auto-update feature installs a defective driver version.
Manually updating the drivers fixed my problem. Thanks for the help

Still going to try that for optimization, thanks
