Hi all, sorry to bother you. I have the latest Photoshop CC with 3D and the new flame filter, however when I try to use it won't let me check OpenCL - It's grayed out and I can't work out why. I have an Intel HD 4000 card which, to my knowledge, should support the extra PS features. I tried to check for updates but the message I received stated that 'A customized computer manufacturer driver is installed on your computer' basically, I can't run Intels own driver updates. I have an ACER Aspire ES1-512-C50S running 64bit Windows 8.1 and so far as I can tell, everything is up to date. Can anyone tell, from the information I've provided, what the problem may be? Thank you very much and sorry I'm not very tech savvy!
