After making some cleanup on my SSD (CCleaner) and removed old nvidia drivers to make a fresh install I noticed that Blender runs extremely slow, like 1 fps with a starting cube.
I tried removing Blender and reinstalling, but no help. Everything else runs as it should (unreal engine, Zbrush). The processor usage during Blender is low, but it’s still slow.
The laptop is quite fast (i7HQ, 850M)… no idea what cold happened with my favorite app
****Edit: forcing integrated graphics solves the problem for now. I guess something is wrong with the newest nvidia driver…
we need to sticky this solution for optimus laptops.
The Procedure:
-first get the latest intel HD AND nvidia drivers (make sure to pick the right models)
-uninstall Nvidia related stuff (not the driver) and restart
-uninstall “NVIDIA Graphics Driver XXX.XX” and restart
-uninstall “Intel Graphics Driver” and restart
-(optional) reboot into safe mode and run a graphics driver cleaner. nowadays this isnt always necessary.
-install the intel driver and restart
-install the nvidia driver and restart (check the box that says “clean install” or something like it)
To get the most of it:
-open the nvida control panel to “Manage 3D Settings” and select “High Performance NVIDIA Processor” as your preferred gpu
-set the “Power Management mode” to “Prefer Maximum Performance”
-set the “Shader Cache” to OFF
-(optional) set “Texture Filtering Quality” to “High Quality”
now stop using C-Cleaner. its dangerous and meant for techies, despite the fact they make it seem otherwise. if you really want to make your computer faster, then reinstall the OS from scratch, no partition images. mine is long over due
Thx for the tips. OldNvidia drivers took up 10gb of spaces, so i desperately needed a solution (living on SSD). (DDU, display driver uninstaller) Fixxed the issue, but after reinstall I got this problem, but only with blender. I might try to remove intel drivers too and make an other full install of optimus drivers, but right now I’m just glad it works at all.
