My blender is so laggy that its unusable, any suggestions So, two days ago I shut down my computer for a few hours. When I turned it back on and opened Blender, it was extremely slow and still is. (I've tested Unreal Engine and it runs smoothly). All the solutions I found involve Nvidia processors but I use Intel and I've had no luck finding issues.

Processor: Intel(R) Core(TM) i3-8130 
Laptop: LENOVO
OS: Windows 10


Any suggestions would be appreciated.
I found the answer. Might be a bit confusing.

So when I turned my computer back on it said my driver was not compatible, so I looked online. I got a file called "opengl32.dll" which let me open blender, thats when I found the lag.

I recently updated my graphic drivers and the lag was still happening, so I removed the "opengl32.dll".

So pretty much, I had to update my graphics driver and not add in that file. Thank you for the answers though :)
