Gta 5 vram usage high

[Marius love ltt]

I'm playing a reloaded version of gta 5, and was having a pretty decent experience, until my fps started going from a steady 30 to 10-20, even if I play with settings on minimum. So I started digging in my graphics settings and doing som research. Then I noticed that the game said it needed about 2gb of vram out of 1gb (which is weird since I am using an amd radeon r5 m430 2gb). In 1080p with everything either off or normal. But the thing is I see people able to get 1080p with vram hungry things like shadows and textures at high while only needing about 1850mb of vram. I am using a Lenovo ideapad 500 15-acz with an amd a10 8700p  4 core cpu at 2.3ghz (60%being used while playing), an amd r5 m430 2gb dedicated gpu with a core clock of 1100mhz and a memory speed of 1000mhz (with the latest 18.8.1 drivers), 8gb of ddr3 memory and a 5400rpm 1tb hdd.
