Hello! I recently changed my pc to one with i7-4770 and I am waiting for my video, using the integrated graphics. All drivers seem to be up to date and I allocated 512 using RAM. I have 8 RAM, so 512 VRAM uses 4 GB. Is it safe to increase it up to 1GB VRAM using all the 8 RAM? PLEASE HELP I AM DYING INSIDE WITHOUT 1 VRAM.
