I'm running on Windows 10 and my graphics card is: Intel(R) HD Graphics 520
Broken on version Blender 2.78
What happened was lately, i was using blender and everything was smooth and things were fine, until seconds later my software suddenly got really slow, so i waited for a few days and went back to my computer to see if it works and when i did, nothing; it is still very slow, so slow that it may be 1 frame per 4 or 5 seconds. I have been looking for solutions all over the internet but there's no luck.
This error or glitch just happened for no reason, all i can tell you is: I was using blender and everything was fine until minutes later, it got very very slow out of no where.
