unity editor (5.5.0f3) stutters, unusable

unity editor (5.5.0f3) stutters more and longer through 2 mins and then becames unusable (running in dx11)
i saw that force opengl helps, it did but when i tried to play the scene unity crashed

What kind of graphics card to you have, ATI or other; does your GPU use switchable graphics?

Nvidia GTX 960 4g, it doesn’t
edit: it actually does happen in opengl mode too

Is it a new install of Unity? Did you try using Unity after completely restarting your computer?

i updated from 5.4, i unistalled my gpu drivers, restarted pc many times

i tried to play a scene on dx11 and on the stats there is CPU main : 2087.5ms

Is the editor taking up most of your memory when running? Or do you have any audio software installed and running such as Nahimic or Sonic Studio (audio drivers can sometimes interfere with the graphics drivers)?

only 3gb out of 8, i have realtek drivers, no software running
but it seems it works now
i have unplugged my gpu from motherboard and plugged it again when i got a bluescreen in one of games i was playing
i guess my gpu or psu is damaged i dont really know

Hmm okay, maybe your drivers need an update? But glad you solved it at least :slight_smile:
