Memory guide

How much RAM, and how fast?

Capacity decides whether textures stream smoothly or freeze the game. Speed decides how steadily the CPU can feed the GPU. Both are modelled here.

Capacity by preset

Measured with a 24GB graphics card so VRAM never interferes. System needs about 3.5GB. "Stutters" means freezes of 80 to 250 ms in the simulator.

Frame ceiling is the most FPS the memory can feed regardless of GPU. Jitter is the random frametime wobble that drags 1% lows below the average.

Try it

Watch the stutter that only the smaller kit produces at 1440p Ultra.
