System Information
I have a windows computer

I have 16 GB of ram and Nvidia GEFORCE GTX 870M
Blender Version
Broken: Blender 2.74-2.7x
Worked: Blender 2.70
I am a Minecraft GFX Designer and when I started to use blender 2.78, everything was working perfectly fine. Running smooth and works well. Then, I heard of Timy's rig that allows me to do Minecraft GFX and I found out that blender 2.78 does not work. I went to the old downloads website and downloaded blender 2.70. Later, the version was too old for some addons that I needed and then when I downloaded blender 2.75, everything was laggy. There were just 5 seconds delays. I found a solution by right-clicking blender and run with integrated graphics. Which seems to have fixed the problem but it is still laggy. I tried almost everything I can do to fix this issue and it does not look like that many people are experiencing the same issue that I am facing. I uninstalled the program and installed it countless times. Restarting my PC does nothing.
I just start up my blender and it lags as heck.
PLEASE HELP ME!!!

Hi, it seams lag is result of auto update display driver on Windows.

If you have side-by-side GPU's, switch to your integrated graphics, and performance will be restored. That's a workaround; I'd be grateful for a solution, because I have the same problem.
Yes, I know that the integrated graphics is the solution but for some reason I see in brackets default. When I open it with that as default, it still has the same issue. When I run blender with the integrated graphics by physically right clicking it and click run with graphics, it works fine. Do you always run blender with that extra right click?
Nope. Never did until the driver changed on the 10th. Now I invoke Blender from the taskbar, where the default is set to use NVidia, and if the program is laggy I close out and invoke it again from the desktop icon with a right-click so I can select the integrated GPU and get to work. That's how I've been informally testing to see whether the problem has been resolved.
If it's the responsibility of us end users to throw rocks at the window until the problem gets noticed by the appropriate people, then I would be grateful if someone would give us directions to the right window.
Oh, I forgot to answer your other question. To set NVidia as the default, you have to go into the NVidia control panel (right click anywhere on desktop) and select ""Manage 3D settings" from the panel on the left. From there you can specify which programs you want to always run under the NVidia GPU.

Please do not set priority of tasks yourself, especially not to high priorities!
And please search for similar reports before creating new ones.
And please do not change editing policy either!
