I really need some help here. Every time I try to render lighting effects I get the message "could not apply the workspace because there is not enough memory (RAM)".
First, this message popped up: "The 3D features requires that "Use Graphics Processor" is enabled the performance preferences (it is). Your video card must meet the minimum requirements and you may need to check that your driver is working correctly." That goes away after one time, but the lack of RAM one still persists.
Everything was working perfectly the other day and I haven't changed anything since I got the message. I restarted the computer, uninstalled/reinstalled PS CC 2015, and updated my graphics driver but obviously, nothing has worked. I have 4GB of RAM by the way and am using Windows 8.1. The graphics card is old and weak, but like I said it was doing its job a few days ago.
Please help. I feel like tearing my hair out.
