# GPU and VRAM

Resolution is a VRAM decision first. Size the tier, then tune speed.

## Facts (2026-10-13)

- **8 GB:** Native resolution, Stable titles
- **12 GB:** Beta open worlds, higher resolutions
- **16+ GB:** 4K reference configs with headroom
- **Rule:** VRAM first, GPU speed second

## VRAM tiers

| VRAM | Resolution | Scope |
| --- | --- | --- |
| 8 GB | Native | Stable titles, capped |
| 12 GB | Raised | Beta open worlds |
| 16+ GB | 4K reference | Quality modes with margin |

## Why VRAM decides first

Translated titles hold console-sized texture working sets plus pipeline overhead. When VRAM exhausts, the driver pages to system RAM and frame times collapse regardless of GPU speed. That is why [Marvel's Spider-Man 2](/library/marvel-s-spider-man-2-ps5-emulator) dips downtown on 8 GB cards while lighter titles hold.

Size the tier first: pick resolution by VRAM, then tune quality by GPU speed. The envelope is in [Minimum and recommended](/hardware/minimum-recommended).

## Tier guidance

- 8 GB: native resolution, Stable titles, frame cap on. Start with [Stable titles](/compat/stable-titles).

- 12 GB: Beta open worlds at raised resolutions; downtown districts and dense effects hold.

- 16+ GB: 4K reference configs such as [Demon's Souls](/library/demon-s-souls-ps5-emulator) quality mode with margin.

All tiers need current drivers and a passing [Vulkan check](/reference/vulkan-check). Build: [Download Meridian](/download).

## FAQ

### Why does resolution hurt more than quality settings?

Resolution scales the VRAM working set directly. Quality settings scale GPU math. Exhausted VRAM pages; slow math just slows.

### Can system RAM substitute for VRAM?

No. Paged VRAM collapses frame times. Size resolution to physical VRAM.

### Which title tests VRAM best?

[Marvel's Spider-Man 2](/library/marvel-s-spider-man-2-ps5-emulator) downtown traversal — two passes, second is the measurement.
