VRAM Usage - Image quality vs performance - and comparison

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, we already addressed this bit of course. But let's have a look at the chart below. The listed MBs used in the chart is the measured utilized graphics memory during our testing. 

The game will eat up and fill your VRAM as much as it can with a bit of reserve. Above some random cards ranging from 6 GB up-to 11GB, all of them utilizing a close maximum VRAM available, that's including the measurements at 4K Ultra HD, well .. a screen resolution of 3840x2160. With the graphics memory filled you are not going to notice anything weird, the game runs very smooth overall. 

Image quality modes

Let's have a peek at the best and worst image quality differences and the performance effect of them. The game offers four preset quality modes ranging from low to ultra quality. We'll be comparing them starting at medium, mostly backgrounds like mountains, vegetation, shadows, and water effects are responsible for the biggest differences.

Let's again take the GeForce GTX 1660 Ti as an example, this is a pretty nice mainstream to high-end card that could benefit from a different quality mode.  We'll take WQHD, or (Wide) Quad HD as-as resolution of choice:

So from Ultra to medium quality, there's a ~40% performance bracket to play with image quality wise relative to performance.

This game offers four preset quality settings modes. Differences in low and normal quality modes are mostly based on settings like shadows and number of ambient effects, from there onwards with the high and highest ultra quality modes, texture quality. Pretty much any modern age graphics card can run at least high-quality settings, maybe even ultra quite well. The ultra-quality preset is obviously the best-looking mode available which is our aim as a PC gamer. 

Quality comparison

The recently introduced image slider system seems to be appreciated so below you can compare three quality modes (Medium compared towards Ultra Quality). We'll try and update these later with better scenery.
