For some strange reason, whenever I use photoshop now, zooming in and zooming out is clunky and not as smooth as it used to be, I can't use finger gestures as easily, and I've tried fiddling with just about everything in an attempt to fix it all, going as far as fiddling with Performance options, purging my cache, and even resetting all of my preferences, but none of it seemed to work. I couldn't tell for the life of me what's going on here, so I need some help. Could anyone possibly point out what could be going wrong and have a solution to fix it?
UPDATE: Okay, so this is really bizarre. I actually bothered to go back and install a slightly older update of Photoshop, and it works perfectly fine for some reason. Everything is at full functionality, there's no lagging issues or anything present, just the same photoshop I was using before the update. Did something happen with the update that makes photoshop too demanding of my graphics card or something, or is there something I need to update on my computer?
