Im receiving the "3d features require a minimum of 512mb of vRAM. photoshp has detected less than that on your system" message. I have updated my drivers and my specs are: i7 2600 CPU amd radeon 7800 gpu & 16 gb of ram. I can see that openGL is disabled and the graphics processor settings under performance is grayed out.…
check if photoshop is started with the right GPU If you use a laptop, you can right click the .exe and select which GPU you want it to run and you possibly run it with your Intel4000 integrated GPU
