So I’ve been using PS CS6 to work with concept art for a while now, and since I formated my PC, I’ve been having some issues with the OpenGL, it seems that my photoshop doesn’t recognize it or something (or my graphic card, I’m not sure). Thing is; sometimes my PS starts smoothly, with everything working just fine, but when I close it and re-open it, some funcions like the canvas rotation or propper anti-aliasing on broken zoom values (like 33,33%) just stop working (“could not complete your request because it only works with OPENGL enabled document windows”).
Right now I’m using windows 7, 64 bits, 16GB Ram and Intel® HD Graphics 4000. I’ve tried reinstalling the drivers multiple times but it just goes the same: It works, but it’s still VERY instable (like, for each 20 times I open my PS CS6, only one is actually working properly).
You might try posting this on a Photoshop forum as you’re more likely to find others that have hit exactly the same problem or could give you targeted Photoshop troubleshooting tips.
I do notice that your GPU is listed here:
[li]Photoshop graphics processor (GPU) card FAQ [/li][/ul]
as explicitly unsupported. This seems to be an older list (as it doesn’t include the absolute latest GPUs for each vendor), and even it says they don’t support your 2012 Intel GPU as of its writing.
If it were me, I think I would just pick up an NVidia GPU card and install it with the latest NVidia graphics drivers. Their drivers are robust, well tested, and very stable, and you’re likely to see much better performance with it than the Intel GPU embedded in your CPU chip.
