Test System

Benchmark scores in other reviews are only comparable when this exact same configuration is used.

We used the press review version of Metro Exodus. We also used the latest drivers from NVIDIA and AMD, neither of which has a game ready driver available yet.

Graphics Memory Usage

Using a GeForce RTX 2080 Ti, which has 11 GB of VRAM, we tested the game's memory usage at the highest settings.

VRAM usage at Ultra can be described as "acceptable" for lower resolutions, with 3 GB at 1080p. Every recent graphics card from this segment should be able to handle memory requirements. For higher resolutions, memory requirements are very modest—all modern graphics cards that can drive these resolutions have 8 GB of VRAM or more.

It's interesting to see that enabling RTX has a constant, resolution-independent VRAM cost of around 1 GB, which can be explained by the additional memory consumed by the data structures to store the geometry, which are used to accelerate ray-testing.

Enabling DLSS only adds another 250 MB of VRAM use, which is pretty much negligible.
