Blender is unable to used without a significant delay in any action (up to four seconds). There is no option to run through graphics processor. My drivers are up-to-date and my graphics card is brand new.
What version of blender?
/ 8gb ram (7.89 available) / gtx 1050
Is this on an empty startup?
Check you haven’t got some insane levels of subsurf, bevel etc. Try turning simplify on and set everything to minimum to see if that has an effect to point you in the direction of the cause.
