I have a intel core i7 2600. My screen resolution is 1920x1080 @ 60Hz via vga port. Motherboard Gigabyte H61M-S2P-B3. Ram 1x Dynet 4GB @ 1333MHz and 1x Corsair 2GB @ 1333MHz. Total 6GB of Ram. I dont have any dedicated graphics card. So I use built in one. But it seems my photoshop struggles to work With my processor Built in graphics. It only take 5 to 10 second to open and Saving a big photo is also fast (There is no problem with Disk speed). But I have some problem with screen flickering. I always work on 8 bit/channel and RGB or CMYK color(I didn't use 16 bit or 32 bit). I don't know what is 8bit, 16bit and 32 bit channel on photoshop. I am designing a 1600 by 3000 pixel template. With 8 bit RGB color. I have searched online for "photoshop cs6 black screen flickering issues" and found some solution. one of them say just change the image mode 8 bit to 32 bit from the image menu. like this:
the problem is I have faced some problem to follow the solution. First, when I click on 32bit/Channel photoshop tells me to merge all the layers. Like this:
But I can't do this because I need layers as they are now. So I clicked on "Don't Merge" button and then photoshop tell me to Flatten visible layers and discard hidden layers. Like this:
I Don't want to make layers flat and discard hidden layers. So I pressed cancel.
