I agree that a better GPU would be great but don't use this excuse to save your day because Studio has problems. a better GPU will provide faster results but Studio, in general, can use any graphic cards and still provides a good functionality.
I am fully aware that a GPU would render my image in 1 minute whereas my old graphics card would render it in 5 minutes; that's my own problem. Still, Studio has to work right, slow or fast. This is the point.
Sometime ago, your Support (which used to be fast and now is very slow) blamed my old graphics card for loosing my presets from Impression to Impression 2!
With the latest Studio, is also the old graphics card when I press OK and the image that shows on PS is a blank image?
Come on, guys! There are Studio issues and there are graphics card issues. Let's be clear on this point.
