really bad camera view lag

my camera view has started lagging really badly today,yesterday was fine. The project im working on is only small, and prior projects have been a lot bigger and have had no issues, I have tried loading these projects today and they are also lagging really bad now.

im using a wacom cintiq companion with a 24hd display.
ive tried reinstalling drivers and have checked all my graphics drivers are up to date

any help would be appreciated

all fixed, had to rollback this recent windows/Wacom update
