Hello everyone.
Recently i tried my hands on GTA 5, with my PC.
PC specs:
Intel i5 3330 3GHz quad core.
Nvidia GTX 645 1GB
Integrated Intel Graphics
Ram 8GB
The Rig: Alienware X51 R1

When i used the GeForce Experience settings, the Vram usage in GTA 5 displayed 2GB used over available 1 GB. I reduced my settings to bare minimum and now it uses 993MB
out of 1 GB. Still I experience frame rate drops (60-30 FPS). I need a stable FPS.
Any help would be appreciated.

All you can really do is lock your framerate to 30FPS in the Nvidia Control Panel by enabling Half Refresh Vsync, that will make your framerates more consistent hopefully, though you probably will still dip below 30FPS. Other than that, the only other thing you can do is look for the ultra low graphics mods, which disables a bunch of graphical features to improve performance on very weak GPUs. The game will look really ugly, but it might improve performance for you.

That is okay. I know that i need to upgrade my graphics card but is there any other immediate solution to this problem?
I have heard of some techniques to increase your dedicated Vram through BIOS. Is that a solution?

Just one more question guys, what about those Nvidia GeForce Experience settings which make me use 2 GB Vram out of available 1 GB? They are supposed to be optimal settings for my GPU. Then how does it use more than available Vram?
