Increasing RAM generally reduces the strain on VRAM because more data can be handled simultaneously.

You're seeing smooth performance despite the hardware specs. The key lies in how the game manages resources under extreme settings. Even with a large VRAM and high-end GPU, factors like CPU load, background processes, and file system efficiency play a role. Since you're on an HDD, faster storage can help reduce latency. Your setup suggests strong hardware, but optimizing startup games or closing unnecessary apps can further boost frame rates.
You need sufficient VRAM as long as it’s available. More system RAM usually doesn’t lower VRAM needs unless specified. All components—CPU, VGA, etc.—must adjust so your frames appear on the screen.
VRAM refers to the memory on your graphics card, right next to the chip. When needed, it allows quick access to data for rendering images. From the card's perspective, system RAM works differently than regular RAM—it's slower. If there isn’t enough VRAM, the game engine must frequently move data between the card and RAM in small portions like 64 MB, 128 MB, 256 MB or 512 MB. When the card needs information not stored in VRAM, it can temporarily take it from VRAM to free space, then send it back via a PCIe slot. The number of PCIe lanes and their type can speed up this process. More RAM helps the game prepare ahead, keeping more data in memory and swapping chunks efficiently. It also increases bandwidth for the memory controller, such as using dual channels instead of single ones or higher-rank sticks.
When performance drops, it usually means you're running low on VRAM instead of RAM. RAM supplies data to the CPU, while everything related to GPU processing moves from VRAM. If you constantly shift data between RAM and VRAM, you create a huge bottleneck that slows things down and causes significant delays. In reality, adding more RAM or VRAM doesn't help if you're already lacking enough. The issue becomes clear once you run out of space.
