GPUs used - quality modes and VRAM usage

The graphics cards tested

In this article, we'll use the setup of the following graphics cards at properly good PC graphics quality. The quality mode, as shown, always has Vsync disabled. The graphics cards used in this test are: 

The glacier engine promises some pretty good rendering quality with high framerates, later this year DirectX Raytracing support will be added, we have not heard anything about further optimizations such as DLSS. 

Graphics memory (VRAM) usage

How much graphics memory does the game utilize versus your monitor resolution with different graphics cards and respective VRAM sizes? Well, let's have a look at the chart below compared to the three main tested resolutions. The listed MBs used in the chart are the measured utilized graphics memory during our testing. Keep in mind; these are never absolute values. Graphics memory usage can fluctuate per game scene and activity in games. This game will consume graphics memory once you start to move around in-game; memory utilization is dynamic and can change at any time. Often the denser and more complex a scene is (entering a scene with lots of buildings or vegetation, for example) results in higher utilization. With your max quality settings, this game tries to stay at almost an four to 6GB threshold. Mind you, the VRAM results are based on ultra quality in-game. VRAM behaviors are tested with the RTX 3090 as it has 24 GB of graphics memory available.

Utilized graphics memory will vary a lot per scene and where you are in the game. As you can see the Hitman III VRAM requirements are very low. Even a 6GB graphics card at Ultra HD will suffice.
