I am experienceing a couple of oddities that I discovered after my last Photoshop update. One is the perspective warp feature remains greyed out no mater the layer state whether it be a smart object, rasterized, etc. The other is the red visual display of brush size and hardness when changing on the fly appears to have gone away.
Thank you for the feedback. I know on a previous Photoshop update the function I meantioned in regards to the brush view displaying in red had gone away but a later update had resoved that issue. This is what I see when navigating to the Performance section of the preferences as you suggested. The "Use Graphics Processor is greyed out. Would downloading a driver update from NVIDIA help you think?
