Increaded UMA buffer size -not sure if helping

So I have a crummy asus desktop I'm trying to turn into something useable. It has an AMD A8 APU with a built-in Radeon 7000-something GPU. I also have an Nvidia 430/1g card.

Right now I'm using the APU. I have bumped up the "uma frame buffer size" to 2G since I have extra ram. I'm not sure/can't tell if this is helping anything or not. I can wander around semi-comfortably using a Singularity alpha with ALM enabled and DOF -FPS is around 20, 21. Turning on shadows kills it, though, and drops my framerate down to the single digits.

I'm suspecting this means the framebuffer increase isn't helping -but I'd like feedback and suggestions.

I can get in on either card, but I have to have ALM etc turned off if I want decent framerates.

[edit]Right now I'm using windows 10 creators' update, and I've downloaded and installed the radeon drivers from AMD.
