When i run rift i have to run it on the lowest possible settings and get lucky if i achieve 15 fps. I know that my computer should be able to run it no problem on those settings. Ive tried to change the allocated RAM for the GUI but cant even find out how much is allocated to it. I'm on a Sony Vaio, windows7, 4G RAM, intel i3, and "Intel graphics media accelerator" as the graphics card, or thats what its told me.

Ive eliminated every problem i can think of except not having enough RAM allocated to the graphics. How can i access and change it if needed, and/or what else could be the problem?
