I recently updated to 2.78 due to getting a new graphics card that was not supported by 2.77, but I've run into an issue with pose mode. Previously on 2.77, I could run it at full speed in material view, but since 2.78, it dips into the low 20s or high teens FPS when moving objects. It goes as far as locking up the programme if I try to type in scale factors.
I know that switching to texture/solid mode is a workaround for this, but I would much rather know if there is a way to actually fix this issue.
